JAMB UTME - Home Economics - 2025

Answer Details

Maintaining a clean and hygienic home environment depends on implementing a regular cleaning schedule. A consistent routine ensures that all areas of the home - kitchen, bathroom, living spaces, and bedrooms - receive attention at appropriate intervals. Daily tasks (washing dishes, wiping surfaces, sweeping floors), weekly tasks (mopping, vacuuming, laundering), and periodic tasks (deep cleaning appliances, washing windows) are planned and carried out systematically rather than left until problems become visible.

A regular schedule prevents the buildup of dust, grease, bacteria, and allergens that contribute to poor indoor air quality, pest infestations, and the spread of illness. It also distributes the workload evenly, preventing the overwhelm of having to tackle a heavily soiled home all at once.

The other options do not address hygiene effectively. Investing in expensive furniture has no bearing on cleanliness - an expensive sofa accumulates dust just as readily as an affordable one. Having a large storage space helps with organisation but does not ensure that surfaces and living areas are sanitised. Using strong chemicals for cleaning can actually be counterproductive: harsh chemicals may damage surfaces, irritate skin and airways, and pose health risks to household members, especially children. Effective cleaning relies on appropriate products and consistent application, not chemical strength.

Answer Details

The placenta is a temporary organ that develops in the uterus during pregnancy and serves as the vital interface between the mother and the developing foetus. Its primary function is to supply oxygen and nutrients from the mother's blood to the foetus and to carry waste products (such as carbon dioxide and urea) from the foetus back to the mother's circulation for disposal.

This exchange occurs across the placental barrier, where maternal and foetal blood come into close proximity without mixing directly. Oxygen and dissolved nutrients (glucose, amino acids, vitamins, and minerals) diffuse from the mother's blood into the foetal blood through the chorionic villi, while waste products move in the opposite direction.

While the placenta does produce hormones (such as progesterone and human chorionic gonadotropin) that help maintain pregnancy, this is a secondary function - not its primary one. The question asks specifically about the primary function, which is the life-sustaining supply of oxygen and nutrients to the foetus. Cushioning the foetus from external shocks is the role of the amniotic fluid, not the placenta. The placenta supplies the foetus, not the mother, so the option referring to providing nutrients to the mother misidentifies the direction of transfer.

Answer Details

Resources in Home Economics and management are classified into two broad categories: material (tangible) resources and human (intangible) resources. Material resources are physical, concrete items that can be seen, touched, counted, or measured. Human resources are the skills, knowledge, attitudes, energy, and relationships that people bring to a task.

Office equipment - such as computers, printers, desks, and filing cabinets - is a material resource because it is a tangible, physical asset that can be purchased, inventoried, and used directly in carrying out work.

The other options are all human or intangible resources:

• Employee skills are a human resource - they represent knowledge and abilities that reside in people, not in physical objects
• Business partnerships are a relational or social resource - they represent connections and agreements between organisations, not physical items
• Company culture is an intangible resource - it comprises shared values, norms, and practices that cannot be physically measured or stored

Exam tip: To classify a resource, ask whether it can be physically touched or counted. If yes, it is material. If it exists as a quality, skill, or relationship, it is a human or intangible resource.

Answer Details

Water spots form when water droplets evaporate and leave behind mineral deposits on a surface. Stainless steel is particularly prone to this problem because its smooth, reflective finish makes even small mineral residues highly visible. Unlike granite, laminate, or ceramic tile, stainless steel shows water marks, fingerprints, and streaks very readily.

A stainless steel sink is exposed to water constantly during dishwashing, food preparation, and general kitchen use. If the surface is not dried after each use, calcium and magnesium deposits from hard water accumulate and create dull, cloudy patches that detract from the sink's appearance. Regular drying with a soft cloth after use is the standard maintenance practice recommended for stainless steel surfaces.

Granite countertops, when properly sealed, resist water spotting. Laminate countertops have a matte or textured finish that does not show water marks prominently. Ceramic tile is glazed and generally sheds water without visible spotting on the tile surface itself, though grout lines may stain over time for different reasons.

Exam tip: When a question asks about surfaces prone to water spots, think about which material has the most reflective, smooth finish where mineral deposits become visible - stainless steel fits this description precisely.

Answer Details

Glass surfaces such as windows and mirrors require careful cleaning to avoid scratches, streaks, and damage. The recommended approach is to spray a suitable glass cleaner directly onto the surface and wipe it with a microfiber cloth. Microfiber cloths are made of extremely fine synthetic fibres that trap dirt and absorb moisture effectively without leaving lint or streaks behind.

Abrasive cleaners and rough sponges scratch glass, permanently damaging the surface. Vigorous scrubbing with a damp cloth alone does not effectively dissolve grease or grime and tends to redistribute dirt rather than remove it, often leaving visible streaks. Paper towels shed fibres that cling to glass, and harsh chemicals can etch or damage glass coatings, frames, and surrounding surfaces.

Spraying cleaner directly onto the surface and wiping with a microfiber cloth is the correct method because it combines effective soil removal with a lint-free, streak-free finish while preserving the integrity of the glass.

Answer Details

A slow cooker (also called a crock-pot) is a countertop electrical appliance that cooks food at low temperatures over an extended period, typically 4 to 10 hours. Its primary benefit is hands-off cooking and the tenderisation of tough cuts of meat.

The hands-off nature means that once ingredients are placed in the pot and the desired setting is selected, the cook can leave the appliance to work unattended. This is particularly convenient for busy households, as meals can be prepared in the morning and ready by evening without constant supervision. The low, slow heat is ideal for breaking down the collagen in tough, inexpensive cuts of meat (such as chuck, brisket, or shanks), converting it into gelatin and producing tender, flavourful results that would require hours of careful monitoring with conventional cooking methods.

The other options contradict the fundamental characteristics of a slow cooker. It does not offer quick cooking time - slow cooking is inherently a long process. It is not designed for high-heat searing; the temperatures are too low for browning. Limited cooking capacity is inaccurate - most slow cookers have generous capacities ranging from 3 to 8 litres, suitable for family-sized meals.

Answer Details

The primary role of human resources (HR) in an organization is to recruit, train, and develop employees. The HR function centres on managing the people who make up the workforce.

HR's core responsibilities include:

• Recruitment and selection: identifying staffing needs, advertising positions, screening applicants, conducting interviews, and hiring the right people for each role.
• Training: ensuring employees have the knowledge and skills needed to perform their jobs effectively, through induction programmes, on-the-job training, and professional development courses.
• Development: supporting career growth through mentoring, performance management, succession planning, and opportunities for advancement.
• Employee welfare: managing compensation, benefits, workplace health and safety, and employee relations.

The other options describe functions of different departments within an organization:

• Managing financial assets is the responsibility of the finance or accounting department.
• Procuring raw materials is handled by the procurement or purchasing department.
• Maintaining physical infrastructure falls under the facilities management or operations department.

Human resources is sometimes called "people management" because its central concern is always the human capital of the organization.

Answer Details

Kitchen utensils and equipment should be sanitized after each use. This is the standard food safety practice because utensils come into contact with raw and cooked foods, each of which may carry bacteria, allergens, or other contaminants.

Sanitizing after each use prevents cross-contamination, which occurs when bacteria from one food item (especially raw meat, poultry, or fish) are transferred to another food via a shared utensil, cutting board, or surface. Pathogens such as Salmonella, E. coli, and Campylobacter can survive on surfaces for hours or even days if not properly cleaned.

The sanitizing process involves first washing the utensil with hot soapy water to remove visible food residue, then rinsing, and finally applying a sanitizing solution (such as a dilute bleach solution or commercial sanitizer) or using very hot water. The utensil should then be air-dried.

Sanitizing only daily, weekly, or monthly leaves utensils contaminated between cleaning sessions, creating opportunities for bacterial growth and foodborne illness. In a busy kitchen where utensils may be used multiple times a day with different foods, after-each-use sanitization is essential.

Answer Details

The question asks which principle of home management emphasizes planning and organization. The correct answer is that all of the listed principles inherently involve planning and organization.

Time management is fundamentally about planning how to allocate the limited hours in a day. It involves creating schedules, prioritizing tasks, setting deadlines, and organizing activities in a logical sequence to make the most efficient use of time.

Problem-solving requires an organized, systematic approach: identifying the problem clearly, gathering relevant information, generating possible solutions, evaluating alternatives, and implementing the chosen solution. Each step demands planning and structured thinking.

Decision-making involves planning by requiring individuals to identify goals, evaluate available options, consider consequences, and select the course of action that best meets the family's needs and resources. Effective decisions depend on having organized information and a clear framework for evaluation.

Since all three principles rely on planning and organization as core components, no single option captures the full answer. Time management plans the use of time, problem-solving organizes responses to challenges, and decision-making plans the selection of the best course of action.

Answer Details

When shopping online, protecting personal and financial information is critical because data transmitted over the internet can be intercepted by malicious actors. The most important step a consumer can take is to verify that the website uses HTTPS (Hypertext Transfer Protocol Secure) and displays a lock icon in the browser's address bar. HTTPS encrypts the data exchanged between the user's browser and the website's server, making it extremely difficult for third parties to read sensitive details such as credit card numbers, passwords, and personal addresses.

Verifying the website's HTTPS and lock icon in the address bar is the correct answer because it directly addresses the security of the data transmission channel before any sensitive information is entered.

The remaining options all represent risky behaviours. Saving login credentials on public computers exposes accounts to anyone who uses that computer afterwards. Public Wi-Fi networks are often unencrypted, making it easy for attackers to intercept data. Sharing sensitive information on social media makes it publicly accessible and can be exploited for identity theft or fraud.

Answer Details

Food contamination in the kitchen occurs when harmful microorganisms, chemicals, or foreign materials enter food and make it unsafe for consumption. Among the options listed, poor personal hygiene is a well-established and common source of food contamination.

When food handlers fail to wash their hands properly, especially after using the toilet, touching raw food, sneezing, or handling waste, they transfer bacteria such as Salmonella, E. coli, and Staphylococcus aureus to food. Other hygiene failures include touching food with open wounds, not wearing clean clothing, or coughing and sneezing over food.

The remaining options describe practices that prevent contamination rather than cause it:

• Properly stored food keeps items at safe temperatures and prevents cross-contamination.
• Clean utensils eliminate surfaces where bacteria could transfer to food.
• Sanitized equipment removes pathogens from preparation areas.

Maintaining good personal hygiene is considered the first line of defence in food safety. Hand washing with soap and warm water for at least 20 seconds before and during food preparation is one of the most effective ways to prevent foodborne illness.

Answer Details

The primary purpose of storing food in airtight containers is to prevent moisture and pests from entering. Airtight containers create a sealed barrier that blocks external moisture (which promotes mould growth and bacterial proliferation) and prevents insects, rodents, and other pests from accessing the food. This protection is essential for maintaining the quality and safety of stored dry goods such as flour, rice, sugar, cereals, spices, and pasta.

When food is exposed to air, it also absorbs ambient moisture from the environment, which can cause clumping, staleness, and accelerated spoilage. Pests such as weevils, ants, and pantry moths are attracted to food odours and can contaminate supplies if containers are not properly sealed.

The other options describe functions that airtight containers do not perform. Airtight containers do not keep food warm or hot - they are not insulated and are designed for room-temperature or refrigerated storage. They do not add flavour to food. While airtight storage does extend shelf life compared to open or loosely covered storage, it does not do so indefinitely - all food eventually deteriorates regardless of the container, due to factors like natural enzymatic breakdown and oxidation.

Answer Details

The defining characteristic of a randomized controlled trial (RCT) is that participants are randomly assigned to treatment or control groups. This randomization is what distinguishes an RCT from other types of research studies and is the feature that gives it its name.

Random assignment means that each participant has an equal chance of being placed in either the treatment group (which receives the intervention being tested) or the control group (which receives a placebo or standard treatment). This process eliminates selection bias and ensures that any differences in outcomes between the groups can be attributed to the intervention rather than to pre-existing differences between participants.

The other options describe features that may be present in some RCTs but are not their key defining characteristic:

• Studies conducted in a laboratory setting describes the location, not the design. RCTs can be conducted in hospitals, communities, clinics, or any appropriate setting.
• Researchers blinded to participant groups (blinding) is a valuable methodological feature used in many RCTs, but it is an additional design feature, not the fundamental defining element.
• Participants selected based on specific criteria describes inclusion and exclusion criteria, which apply to many study designs, not just RCTs.

Answer Details

A classic red flag for a potential scam is when a company demands immediate payment or threatens negative consequences if you do not comply quickly. Scammers use urgency and fear as psychological pressure tactics - they want victims to act before they have time to think critically, verify the offer, or consult others. Common threats include claims that an account will be closed, legal action will be taken, or an exclusive deal will expire immediately.

Legitimate businesses generally provide reasonable timeframes for payment decisions and do not threaten customers to force hasty transactions.

The other options describe practices that are not inherently suspicious. A free trial with no strings attached can be a legitimate marketing strategy. Payment via credit card or secure online platforms is standard and actually offers consumer protection through chargeback mechanisms. A seller providing clear and transparent product information is a sign of a trustworthy business, not a warning sign.

Exam tip: In consumer education, the key scam indicators to remember are pressure to act immediately, requests for unusual payment methods (wire transfers, gift cards), offers that seem too good to be true, and reluctance to provide verifiable contact information.

Answer Details

When selecting a housing location for a family, the most important consideration is the safety and security of the neighbourhood. A safe environment protects family members - especially children and the elderly - from crime, accidents, and other hazards. Security influences every aspect of family well-being: children can play outdoors, family members can move freely, and the household can function without constant anxiety about personal safety.

In Home Economics, housing decisions are evaluated based on how well they meet the family's fundamental needs. According to Maslow's hierarchy of needs, safety and security are basic needs that must be satisfied before higher-level concerns (such as aesthetics or luxury) become meaningful. A beautiful house in a dangerous area fails to serve its most essential purpose as a shelter and safe haven for the family.

The other options describe secondary considerations. Luxurious amenities (swimming pools, gyms) are desirable but not essential. Proximity to entertainment venues is a convenience, not a priority for family housing. The aesthetic appeal of the house itself relates to personal taste and can often be improved over time, whereas the safety of the surrounding neighbourhood is largely outside the homeowner's control.

Answer Details

A pressure cooker works by sealing the cooking vessel and trapping steam inside. As the liquid heats up, steam builds pressure, which raises the boiling point of water from the normal 100 degrees Celsius to approximately 120 degrees Celsius. This higher temperature cooks food significantly faster than conventional methods.

A key characteristic of pressure cooking is reduced liquid requirements. Because the sealed environment prevents steam from escaping, very little liquid evaporates during cooking. The moisture stays inside the pot, circulating as pressurised steam. This means the cook needs to add far less water or stock compared to conventional boiling, steaming, or braising, where liquid continuously evaporates.

Lower temperatures is incorrect - pressure cooking uses higher temperatures than normal boiling. Longer cooking times is the opposite of what happens - the elevated pressure and temperature dramatically shorten cooking times. Increased nutrient loss is also incorrect; pressure cooking actually preserves more nutrients than many conventional methods because the shorter cooking time and reduced exposure to water limit the breakdown and leaching of vitamins and minerals.

Answer Details

Meal planning is the practice of deciding in advance what meals will be prepared and eaten over a given period, typically a week. One of its key benefits is reduced grocery bills.

When meals are planned ahead, the household can create a precise shopping list based on actual needs. This eliminates impulse purchases, reduces the likelihood of buying duplicate items, and allows for strategic use of bulk buying, seasonal produce, and sales. Because every purchased ingredient has a planned use, far less food is wasted, which translates directly into monetary savings.

The other options describe outcomes that meal planning is specifically designed to prevent. Increased food waste is the opposite of what planning achieves, since ingredients are bought with specific meals in mind. Greater reliance on takeout contradicts the purpose of planning home-cooked meals. More spontaneous meals is the antithesis of planning itself.

Exam tip: Meal planning questions typically test the link between advance preparation and resource efficiency, whether in time, money, or nutrition.

Answer Details

Synthetic fibers such as polyester and nylon are manufactured from chemical compounds derived from petroleum. One of their principal advantages is that they are durable and easy to care for. These fibers resist stretching, shrinking, and wrinkling, and they dry quickly after washing. Garments made from polyester and nylon can typically be machine-washed and require little or no ironing, making them practical for everyday use.

The remaining options describe characteristics that are either inaccurate or represent drawbacks rather than benefits. Synthetic fibers are not biodegradable - they persist in the environment for decades, which is actually an environmental concern, not an advantage. They are not always expensive; in fact, synthetic fibers are generally more affordable than natural fibers like silk or wool. While some synthetic fabrics can pill or snag under friction, this is a disadvantage of the material, not a benefit.

Exam tip: When asked about benefits of synthetic fibers, focus on their practical qualities - durability, wrinkle resistance, quick drying, and low maintenance cost. These are the properties that distinguish them favourably from natural fibers in everyday use.

Answer Details

Cake flour is the flour best suited for making delicate pastries and cakes. It has the lowest protein content among common flour types, typically between 7% and 9%. This low protein content means less gluten is formed when the flour is mixed with liquid, producing a tender, fine-textured crumb that is ideal for cakes, biscuits, and delicate pastries.

Cake flour is also more finely milled than other flours and is often bleached, which further weakens the gluten structure and allows it to absorb more sugar and fat. This results in a moist, soft product with a light texture.

The other flour types have higher protein contents that produce more gluten development:

• Bread flour has the highest protein content (12-14%), creating strong gluten networks needed for the chewy texture of bread.
• All-purpose flour has a moderate protein content (10-12%) and works for a range of baked goods but does not produce the same delicate results as cake flour.
• Whole wheat flour contains the entire grain (bran, germ, and endosperm), making it denser and heavier - unsuitable for delicate baking.

Answer Details

A key benefit of studying Home Economics is enhanced decision-making and problem-solving skills. Home Economics (also called Family and Consumer Sciences) covers a wide range of practical disciplines including food and nutrition, textiles and clothing, home management, child development, and consumer education. Across all these areas, students are constantly required to analyse situations, weigh alternatives, manage resources, and make informed choices.

For example, when planning a family budget, a student must identify income sources, prioritise needs over wants, allocate funds, and evaluate trade-offs. When planning a balanced meal, the student must consider nutritional requirements, available ingredients, cost, preparation time, and dietary restrictions. These exercises build transferable skills in critical thinking, resource management, and decision-making that apply well beyond the classroom.

The other options misrepresent the outcomes of studying the subject. Reduced interest in nutrition and health is the opposite of what the course promotes. Increased dependence on others for household tasks contradicts the subject's core aim of building self-sufficiency. While the subject involves some science (nutrition, textiles) and maths (budgeting, measurement), improved academic performance in science and maths is not a direct or primary benefit of studying Home Economics.

Answer Details

A serger, also called an overlocker, is a specialised sewing machine designed to finish the raw edges of fabric. It uses multiple threads (typically three or four) to simultaneously trim the seam allowance, stitch the seam, and encase the raw edge in thread. This prevents the fabric from fraying and unravelling, producing a neat, professional finish similar to what is seen on commercially manufactured clothing.

To finish seams and prevent fraying is the correct answer because this is the serger's primary and defining function. While a regular sewing machine can construct seams, it cannot efficiently finish raw edges the way a serger can.

Sewing heavy fabrics is better served by an industrial or heavy-duty sewing machine, not specifically a serger. Creating buttonholes requires a buttonhole foot or a specialised buttonhole machine. Sewing straight lines is a basic function of any standard sewing machine. None of these describes the serger's distinctive role in garment construction.

Answer Details

Perishable foods such as meat, dairy products, and eggs must be stored at 40 degrees F (4 degrees C) or below to slow the growth of harmful bacteria. This temperature range keeps food out of the danger zone, which is between 40 degrees F (4 degrees C) and 140 degrees F (60 degrees C), where bacteria multiply rapidly.

At refrigerator temperatures of 40 degrees F or below, bacterial growth is significantly slowed (though not stopped entirely), allowing perishable foods to remain safe for their recommended storage periods. This is the standard guideline endorsed by food safety authorities worldwide.

Storing perishable foods at room temperature or at 60 degrees F (15 degrees C) and above places them squarely in the danger zone, where bacteria like Salmonella, E. coli, and Listeria can double in number in as little as 20 minutes. While freezing (below 0 degrees C) does preserve food for longer periods, the question asks about the recommended storage temperature for regular use, not long-term preservation. Refrigeration at 4 degrees C or below is the correct standard for day-to-day storage of perishables.

Answer Details

A solution is a homogeneous mixture in which the solute particles are evenly distributed throughout the solvent at the molecular or ionic level. Because the dissolved particles are extremely small (typically less than 1 nanometre), they cannot be seen with the naked eye or even under a standard microscope.

Key properties of a solution:

• Particles are uniformly distributed and do not settle over time.
• The mixture appears clear and transparent (though it may be coloured).
• Particles cannot be separated by filtration.
• It does not scatter a beam of light (no Tyndall effect).

Comparing with the other mixture types:

• A suspension has large, visible particles (greater than 1000 nm) that settle out over time. Examples include muddy water and sand in water.
• A colloid has intermediate-sized particles (1-1000 nm) that are evenly dispersed but can scatter light (the Tyndall effect). Examples include milk and fog.
• An emulsion is a specific type of colloid where two immiscible liquids are dispersed in each other, such as oil in water. The droplets can sometimes be visible.

The question describes particles that are both evenly distributed and invisible, which specifically matches a solution.

Reduced grocery bills is a key benefit of meal planning. When meals are planned in advance, the household can create targeted shopping lists that include only the ingredients needed for specific meals, which directly lowers food spending.

Meal planning reduces grocery costs through several mechanisms:

• Eliminates impulse buying: Shoppers with a clear list are less likely to purchase unnecessary items.
• Reduces food waste: Ingredients are bought with specific uses in mind, so less food spoils or goes unused. This translates into financial savings because money is not spent on food that ends up discarded.
• Enables bulk buying and sales shopping: Planning ahead allows the household to take advantage of discounts, buy in bulk when appropriate, and substitute cheaper ingredients where possible.
• Fewer takeout orders: Having a plan and prepared ingredients at home reduces the temptation to order expensive restaurant or takeout meals.

The other options describe outcomes that are the opposite of what meal planning achieves. Meal planning provides structure rather than spontaneity, decreases food waste rather than increasing it, and reduces dependence on takeout rather than increasing it.

Answer Details

Nutrition and dietetics is the study of how food and nutrients affect health, growth, and disease prevention. Among the subjects listed, Biology is most closely related to Home Economics in this area because biology provides the scientific foundation for understanding how the human body digests, absorbs, and metabolises nutrients.

Key biological concepts that underpin nutrition and dietetics include:

• The structure and function of the digestive system (mouth, stomach, intestines, liver, pancreas)
• Enzyme action in breaking down carbohydrates, proteins, and fats
• Absorption of nutrients through the villi of the small intestine
• Cellular respiration and how the body converts glucose into energy
• The role of vitamins and minerals in metabolic processes
• Deficiency diseases and their biological mechanisms

While chemistry deals with the chemical composition of food molecules, and mathematics is useful for dietary calculations, neither is as directly linked to the biological processes of nutrition as biology itself. Physics has minimal direct relevance to nutrition and dietetics.

Answer Details

Cooking in bulk and freezing meals is an effective time-saving strategy in meal preparation. This approach, often called batch cooking, involves preparing large quantities of food at once and storing portions in the freezer for future use. On busy days, a pre-made meal only needs to be reheated, eliminating the need to cook from scratch each time.

Batch cooking saves time in several ways: ingredients are washed, chopped, and measured once for multiple meals; the kitchen is cleaned up only once instead of daily; and cooking equipment is used efficiently. It also reduces decision fatigue because meal choices have already been made.

The other options actually increase the time spent on meal preparation. Using a variety of complex recipes demands more planning, more ingredients, and longer cooking times. Shopping for ingredients daily requires repeated trips to the store. Preparing every meal from scratch means starting the full cooking process each time a meal is needed, which is the most time-intensive approach.

Answer Details

An emulsion is a type of mixture consisting of two or more liquids that are normally immiscible (unable to mix homogeneously). In an emulsion, one liquid is dispersed as tiny droplets throughout the other. The classic example is oil and water.

Emulsions require an emulsifying agent (emulsifier) to remain stable. The emulsifier reduces the surface tension between the two liquids, preventing the droplets from merging and separating. Common emulsifiers include lecithin (found in egg yolk, which is why egg yolk stabilizes mayonnaise), soap, and mustard. Without an emulsifier, the two liquids will eventually separate into distinct layers.

Everyday examples of emulsions include milk (fat droplets dispersed in water), mayonnaise (oil dispersed in vinegar/lemon juice, stabilized by egg yolk), and salad dressings.

A colloid is a broader category where one substance is dispersed in another, but the dispersed particles can be solid, liquid, or gas - not specifically two immiscible liquids. A suspension consists of solid particles dispersed in a liquid, and the particles are large enough to settle out over time. A solution is a homogeneous mixture where the solute fully dissolves in the solvent at the molecular level.

Answer Details

A central objective of Home Economics is to promote independence and self-sufficiency in individuals. The discipline equips students with practical life skills - including meal planning, budgeting, clothing care, child development knowledge, and household management - that enable them to function independently and make informed decisions in their personal and family lives.

This objective reflects the broad, empowering nature of Home Economics: rather than creating dependency, it builds competence across multiple areas of daily living so that individuals can manage their own homes, finances, nutrition, and family responsibilities effectively.

The other options misrepresent the field's scope. Focusing solely on food preparation and cooking reduces Home Economics to just one of its many branches. Emphasising material possessions contradicts the discipline's values of wise resource management and prioritising well-being over materialism. Preparing students for careers in science and technology describes the objectives of STEM education, not Home Economics, although the field may incorporate scientific principles in areas like nutrition and textile science.

Answer Details

A dietitian is a health professional who specialises in food and nutrition, applying scientific knowledge to help individuals and groups make appropriate dietary choices for health, disease management, and well-being. This career falls squarely within the domain of Home Economics because the field covers nutrition, food science, meal planning, and the relationship between diet and health.

Home Economics graduates can pursue careers in dietetics by further specialising in areas such as clinical nutrition (advising patients in hospitals), community nutrition (designing public health programmes), food service management (planning menus for institutions), or sports nutrition.

The other options represent careers in fields unrelated to Home Economics. A mechanical engineer designs and builds mechanical systems and machines, which belongs to engineering. An astrophysicist studies celestial objects and the physics of the universe. A software engineer develops computer programmes and applications. None of these professions draws on the core content areas of Home Economics - nutrition, textiles, child development, consumer education, or household management.

Answer Details

An interior designer plans and creates functional, aesthetically pleasing indoor spaces by selecting colour schemes, furniture, lighting, fabrics, and spatial arrangements. This career is directly related to Home Economics because the field includes the study of housing, home furnishing, textile selection, and creating environments that support family well-being and comfort.

Home Economics courses cover principles of design (balance, proportion, rhythm, emphasis, and harmony), colour theory, textile properties, and space planning - all of which form the foundation for a career in interior design. Students who study Home Economics develop the knowledge base needed to pursue specialised training in this area.

The other listed careers do not draw on Home Economics content. A doctor practises medicine, which requires training in the biological and medical sciences. A pilot operates aircraft, requiring aviation and aeronautical training. A lawyer practises law, which requires legal education. While these are all respected professions, none is rooted in the subject areas covered by Home Economics.

Answer Details

Sweeping or vacuuming regularly and using a gentle cleaning product is the recommended method for cleaning and maintaining hardwood floors. This approach removes everyday dirt, dust, and grit that can scratch the floor's finish, while the gentle cleaner handles stains and spills without damaging the wood.

Hardwood floors have a protective finish (polyurethane, wax, or oil) that preserves the wood underneath. Proper maintenance protects this finish and extends the life of the flooring.

The other methods can damage hardwood floors:

• Applying wax or polish daily leads to excessive build-up on the floor surface, creating a dull, sticky film that attracts more dirt. Waxing should only be done periodically (a few times a year at most) and only on floors with a wax finish.
• Using excessive water and soaking the floor is particularly harmful because wood absorbs moisture, causing it to swell, warp, buckle, and potentially develop mould underneath. Hardwood floors should only be cleaned with a damp (not wet) mop.
• Using abrasive cleaners and scrubbers strips away the protective finish and scratches the wood surface, leaving it vulnerable to staining and moisture damage.

The key principle of hardwood floor care is gentle, regular maintenance that removes debris without introducing excessive moisture or harsh chemicals.

Answer Details

The key factor in preventing pest infestations is storing food in sealed containers and cleaning up crumbs and spills promptly. This approach targets the root cause of most household pest problems: access to food and water.

Pests such as cockroaches, ants, mice, and rats are attracted to homes primarily because they offer food, water, and shelter. By storing all food (including pet food, cereals, flour, sugar, and snacks) in airtight, sealed containers, pests are denied the food sources they seek. Promptly cleaning up crumbs, spills, and food residues removes the scent trails and small food deposits that attract and sustain pest populations. Regularly emptying rubbish bins and keeping them sealed further reduces attractants.

The other options describe practices that would either worsen or fail to address the problem. Keeping the home cluttered provides hiding places and nesting sites for pests. Leaving food and trash in the open actively attracts pests. Using pesticides regularly even when no pests are present is not a recommended preventive strategy: it is both wasteful and can lead to pesticide resistance, environmental contamination, and health risks. Prevention through sanitation and exclusion is always preferred over chemical treatment.

Answer Details

A walking foot (also called an even-feed foot) is a sewing machine attachment that has its own set of feed dogs on top of the fabric. These upper feed dogs work in synchronisation with the machine's lower feed dogs, gripping and advancing both the top and bottom layers of fabric at the same rate. This prevents the layers from shifting, bunching, or puckering during sewing.

The primary purpose of a walking foot is to handle thick or bulky fabrics. When sewing through multiple layers of fabric, batting, or heavy materials such as denim, leather, or quilted layers, a standard presser foot pushes down on the top layer while the lower feed dogs pull only the bottom layer. This mismatch causes the layers to shift unevenly. The walking foot solves this by feeding both layers at the same speed.

Creating decorative stitches requires specialised stitch mechanisms or decorative stitch feet, not a walking foot. Sewing stretchy fabrics is primarily managed by a stretch stitch setting or a ballpoint needle. Quilting intricate designs requires a free-motion or darning foot that allows the fabric to move freely in all directions, whereas a walking foot is used for straight-line quilting only.

Answer Details

Regular uterine contractions that intensify over time are the hallmark sign of true labour. These contractions are rhythmic tightenings of the uterine muscles that gradually become more frequent, longer in duration, and stronger in intensity as labour progresses.

True labour contractions are distinguished from Braxton Hicks (false labour) contractions by several features:

• They occur at regular, increasingly shorter intervals.
• They grow progressively stronger rather than staying the same or fading.
• They do not go away with rest, position changes, or hydration.
• They are typically felt in the lower back and radiate to the front of the abdomen.

The other options are not reliable indicators of true labour:

• Decreased fetal heart rate is not a normal sign of labour onset; it may indicate fetal distress and requires medical attention.
• Nausea and vomiting can occur during labour but are not a primary or defining sign. They can also be caused by many unrelated conditions.
• Increased fetal movement is not a characteristic sign of labour onset. In fact, some women report slightly reduced movement as the baby settles into position for delivery.

Answer Details

When comparing prices of different products, the most reliable factor to consider is the unit price - the cost per standard unit of measurement (per kilogram, per litre, per item, etc.). The unit price allows a consumer to make a fair, objective comparison between products that may come in different package sizes, brands, or formats.

For example, a 500g bag of rice priced at 800 naira and a 2kg bag priced at 2,800 naira cannot be compared directly by their total price. Calculating the unit price reveals that the 500g bag costs 1,600 naira per kg while the 2kg bag costs 1,400 naira per kg, making the larger bag better value per unit.

The other options are unreliable bases for price comparison. A brand name does not guarantee better value - premium brands may charge higher prices for equivalent quality. Advertising claims are designed to persuade, not to provide objective cost comparisons. Packaging design appeals to visual preference and does not reflect the actual value of the product inside.

Exam tip: In consumer education, always distinguish between total price (what you pay at the counter) and unit price (what you pay per standard measure). Unit price is the tool that enables genuine value comparison across products of different sizes and brands.

The kitchen work triangle is a design concept that connects the three primary workstations in a kitchen: the sink, the cooker (stove), and the refrigerator. These three points form an imaginary triangle, and the principle states that the distances between them should be neither too short (causing a cramped workspace) nor too long (causing unnecessary walking).

The primary function of this triangle design is to enable efficient movement between workstations. During food preparation, the cook constantly moves between these three areas - retrieving ingredients from the refrigerator, washing and preparing them at the sink, and cooking them on the stove. A well-planned triangle minimises wasted steps and reduces fatigue, making the cooking process smoother and faster.

While a good kitchen layout may also maximise storage space, improve aesthetics, or increase countertop area, these are secondary considerations. The work triangle specifically addresses the flow of movement during cooking tasks, which is why efficient movement between workstations is the correct answer.

Constructing a sleeve involves several stages, but the key step that is unique and specific to sleeve construction is setting in the sleeve cap. The sleeve cap is the curved upper portion of the sleeve that must be eased into the armhole (armscye) of the bodice. This process requires careful alignment of notches, even distribution of ease, and precise stitching to ensure the sleeve hangs correctly and allows comfortable arm movement.

Setting in the sleeve cap involves:

1. Running an ease stitch (gathering stitch) along the cap between the notches to slightly reduce its length to match the armhole
2. Matching the sleeve's notches and seam points to corresponding points on the bodice armhole
3. Pinning the sleeve into the armhole with the right sides together
4. Distributing the ease evenly so there are no visible puckers or pleats
5. Stitching the sleeve to the bodice along the seamline

The other options describe general garment construction steps that are not specific to sleeve construction. Hemming the bottom is a finishing step for the garment's lower edge. Attaching the collar pertains to the neckline. Sewing the side seams joins the front and back panels of the bodice or skirt. None of these is a defining step of sleeve construction.

High-touch surfaces such as doorknobs, light switches, faucet handles, and remote controls are frequently contacted by multiple household members and can harbour bacteria and viruses. Disinfecting with a product containing EPA-registered disinfectants is the most effective method to sanitize these areas.

EPA-registered (Environmental Protection Agency-registered) disinfectants have been tested and proven to kill specific pathogens on surfaces when used according to the label instructions. They are formulated at concentrations sufficient to destroy bacteria, viruses, and fungi, making them far more effective than general cleaning alone.

The other methods are inadequate for proper sanitization:

• Vacuuming removes loose dust and debris from surfaces but does not kill microorganisms. It is appropriate for floors and upholstery, not for sanitizing hard surfaces.
• Spraying a gentle cleaner and wiping with a paper towel may remove visible dirt and some surface bacteria, but general-purpose cleaners are not formulated to kill pathogens. Cleaning removes contaminants; disinfecting kills them.
• Using a dry cloth to dust merely redistributes dust particles and does nothing to eliminate microorganisms from the surface.

The distinction between cleaning (removing dirt) and disinfecting (killing germs) is important: effective home sanitation requires both steps, with disinfection being essential for high-touch areas.
