Question 1 Report
The average curve and the marginal curve are U-shaped in the short-run and flatter in the long-run due to________
Answer Details
The reason why the average curve and the marginal curve are U-shaped in the short-run and flatter in the long-run is due to economies of scale. Economies of scale refer to the cost advantages that firms experience as they increase their production output. In the short-run, firms are often operating at less than their optimal capacity and therefore may experience diseconomies of scale as they increase output, which leads to higher average costs and a U-shaped average curve. Meanwhile, the marginal cost curve intersects the average cost curve at its minimum point, which is why it is also U-shaped in the short-run. However, in the long-run, firms have more time to adjust their inputs and can increase the scale of their operations. As they do so, they can experience economies of scale, which lead to lower average costs and a flatter average curve. This means that the marginal cost curve intersects the average cost curve at a lower point than in the short-run, making it flatter. Overall, this illustrates how economies of scale can affect a firm's production costs and how this can be reflected in the shape of the average and marginal cost curves.
Question 3 Report
The money market equilibrium is defined as_________
Answer Details
The money market equilibrium is defined as when the demand and supply of money are equal. In other words, the amount of money people want to hold (demand) is equal to the amount of money available (supply). Think of the money market as a marketplace where people buy and sell money. Just like any other market, when there is high demand for a product, its price (in this case, the interest rate) will increase. When there is low demand, the price (interest rate) will decrease. In the money market, the interest rate is a measure of the cost of borrowing money. If there is a high demand for money, people are willing to pay a higher interest rate to borrow it. This results in an increase in the interest rate. On the other hand, if there is low demand for money, people are not willing to pay a high interest rate, and the interest rate decreases. When the demand and supply of money are equal, the interest rate will be at the level where the quantity of money that people want to hold is equal to the amount of money available. This is the money market equilibrium.
Question 4 Report
Whatever form an economic system may take, choice is essential for members of the community because resources are__________
Answer Details
Scarce. This means that there is not enough of a certain resource to meet the demand or needs of everyone in the community. As a result, choices have to be made about how to allocate these limited resources among different individuals, groups, or uses. When resources are scarce, it is important to make decisions about their use in the most efficient and effective way possible.

Answer Details
Question 6 Report
A rise in the supply of a commodity cause__________
Answer Details
When the supply of a commodity increases, it means that there is more of that commodity available in the market than before. This increase in supply causes the market to shift, leading to a change in the equilibrium price and quantity of that commodity. As the supply of the commodity increases, sellers will want to sell more of the commodity, but buyers may not want to buy as much at the higher price. This creates a surplus, where there is more supply than demand, causing the price to decrease. As the price decreases, buyers are more willing to buy the commodity, and sellers may reduce the amount they are willing to sell, until the market reaches a new equilibrium. This new equilibrium will have a lower price and a higher quantity bought and sold than before the increase in supply. Therefore, the correct answer is: a decrease in the equilibrium price and an increase in the equilibrium quantity bought and sold.

Question 9 Report
Economics is a social science concerned with the proper use and______
Answer Details
Economics is a social science concerned with the proper use and allocation of resources for growth. Economics is the study of how society uses its limited resources to satisfy its unlimited wants and needs. It is concerned with how individuals, businesses, and governments make choices about how to use resources to produce goods and services, and how these goods and services are distributed among the members of society. The proper use and allocation of resources are essential for economic growth, which is the increase in the production and consumption of goods and services over time. This growth is achieved through the efficient use of resources to create more goods and services, which can then be distributed to meet the needs of society. Economics helps us to understand how resources are allocated and used in different economies and how these decisions affect the overall well-being of individuals and societies.

In the case of highly or close complementary goods, the indifference curve is_______
Answer Details
Question 12 Report
An economy in which the whole income is not consumed is referred to as______
Answer Details
Question 13 Report
In the short-run, the monopoly makes_______
Answer Details
In the short-run, a monopoly can make abnormal profit. Abnormal profit is a profit that is higher than the normal profit a company would make in a competitive market. This is because a monopoly has market power, meaning it has control over the price of its product and can set it higher than the market price, leading to higher profits. However, it's important to note that this situation is only temporary and in the long-run, competition and other factors can drive down prices and eliminate the abnormal profit.
Question 14 Report
One of these is not a way by which government encourage industrialization?
Answer Details
Low productivity and inefficiency is not a way by which government encourages industrialization. In fact, it is the opposite. Encouraging industrialization means creating a favorable environment for businesses to grow and increase productivity. Low productivity and inefficiency hinder the growth of industries, making it difficult for the government to encourage industrialization. On the other hand, protection of infant industries, establishment of Nigeria Enterprises Promotion Decree, and establishment of higher institutions are ways by which the government can encourage industrialization. Protection of infant industries involves offering support and protection to new and growing businesses to help them establish and grow. The establishment of Nigeria Enterprises Promotion Decree provides support and incentives for local businesses to grow and expand. The establishment of higher institutions provides a well-educated workforce, which is essential for industrial growth and development.

Question 17 Report
As indifference curve shows equal level of satisfaction at all points, An isoquant shows equal level of_________
Answer Details
An isoquant shows equal level of output. An isoquant is a curve that represents all the possible combinations of inputs (such as labor and capital) that can produce the same level of output for a particular product or service. In other words, it represents all the different ways to produce the same amount of output using different combinations of inputs. So, all points on an isoquant represent the same level of output, and this level of output gives us the same satisfaction or usefulness. As we move along the isoquant, we can produce the same output using different combinations of inputs, but the level of output remains constant. In simple terms, an isoquant is a line that shows the different combinations of inputs that can produce the same level of output.

Question 19 Report
The use of government income and expenditure instrument to regulate the economy is termed______
Answer Details
The use of government income and expenditure instrument to regulate the economy is called fiscal policy. Fiscal policy is a tool used by the government to influence the economy by changing the level and composition of government spending and taxation. The main aim of fiscal policy is to achieve macroeconomic objectives, such as controlling inflation, promoting economic growth and stability, and reducing unemployment. When the government increases its spending and/or reduces taxes, it injects more money into the economy, which can increase consumer spending and business investment. This can help to stimulate economic growth, create jobs, and increase aggregate demand. On the other hand, when the government reduces its spending and/or increases taxes, it takes money out of the economy, which can help to cool down an overheating economy and reduce inflation. In summary, fiscal policy involves using government income (taxation) and expenditure (spending) to influence the economy and achieve macroeconomic objectives.
Question 20 Report
The following are measures of location except________
Answer Details
The measure of location that is not a measure of location is "Range". A measure of location gives us an idea of where most of the values in a data set are concentrated. Arithmetic mean, Harmonic mean, and Geometric mean are all measures of location that give us a single value to represent the center of the data set. For example, the arithmetic mean is the sum of all the values divided by the number of values. The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals of the data values. The geometric mean is the nth root of the product of n values. On the other hand, the range is a measure of spread, which gives us an idea of how spread out the values in a data set are. The range is simply the difference between the largest and smallest values in a data set.

Answer Details
In 1976, there were 8 live births for every 1,000 people in the population of the country. This means that for a population of 10 million people, there would be 8 x 10,000 = 80,000 live births in the country.
Question 25 Report
If AC and MC are represented on a graph, the MC curve will cut the AC curve_______
Answer Details
The MC (marginal cost) curve will cut the AC (average cost) curve at the minimum point on the AC curve. This is because the minimum point on the AC curve represents the lowest average cost of production, and the MC curve intersecting the AC curve at this point indicates that the marginal cost of producing one more unit is equal to the average cost. In other words, at the minimum point on the AC curve, any further increase in production would lead to an increase in the average cost.
Question 26 Report
The determination of price by bargaining between buyers and sellers is________
Answer Details
The determination of price by bargaining between buyers and sellers is called Haggling or Higgling. This is a process where buyers and sellers negotiate the price of a product or service, typically in an informal setting. The buyer wants to pay as little as possible, while the seller wants to get as much as they can. They both compromise and agree on a price that is acceptable to both parties. Haggling is common in open-air markets, street vendors, and in some cultures it's a part of the normal purchasing process. In this process, the buyer and the seller communicate and exchange information about the value of the product or service, and how much each is willing to pay or receive. The price is ultimately determined through a give-and-take negotiation, and both parties must agree on the final price for the transaction to occur.
Question 27 Report
Adam Smith's Theory of value stated that the value of a commodity depended on________
Answer Details
Adam Smith's theory of value stated that the value of a commodity depends on the amount of labour expended on its production. Smith believed that in a market economy, the value of a good or service is determined by the amount of work required to produce it. According to his theory, the more time and effort that goes into making a product, the more valuable it becomes. This idea is known as the "labour theory of value." In simple terms, the value of a product is determined by the effort and time put into making it. The more effort and time required, the more valuable the product is considered to be. This theory is considered to be one of the foundations of classical economics and is still widely studied and discussed today.
Question 28 Report
Restrictive monetary policy is designed to curtail aggregate demand and to overcome________
Answer Details
Restrictive monetary policy is designed to overcome inflation. Inflation is when the overall price level in an economy is rising, and the value of money is decreasing. The central bank can use restrictive monetary policy to reduce the amount of money in circulation and decrease aggregate demand, which will in turn help to curb inflation. For example, the central bank may increase interest rates, which makes borrowing money more expensive and reduces consumer spending. It may also sell government bonds, which reduces the amount of money available in the banking system. This type of policy is called restrictive because it restricts or slows down the growth of the economy, which helps to control inflation.
Question 29 Report
The arithmetic mean of 5, 8, 10, 15, 24 and 28 is_______
Answer Details
To find the arithmetic mean of a set of numbers, you need to add up all the numbers and divide the sum by the total number of numbers. In this case, we have six numbers, so we need to add them up and divide by 6. Adding up the numbers, we get: 5 + 8 + 10 + 15 + 24 + 28 = 90 Then, we divide the sum by the total number of numbers: 90 / 6 = 15 Therefore, the arithmetic mean of 5, 8, 10, 15, 24 and 28 is 15.
Question 30 Report
Most of the National debts is "dead weight" in the sense that is____
Answer Details
Most of the national debt is "dead weight" in the sense that it is not covered by any real asset. This means that the debt is not backed up by any tangible property or valuable resource. Instead, it is simply a financial obligation that the government owes to its creditors, who have loaned the government money. The government must pay back this debt with interest, which can add up over time and become a burden on the economy. This type of debt is sometimes referred to as "dead weight" because it does not contribute to the growth or development of the economy, but instead represents a financial obligation that must be met.
Question 31 Report
An economy system that uses what is regarded as the "Market mechanism" is called_______
Answer Details
Capitalism is an economic system that uses the market mechanism. In a capitalist economy, individuals and businesses own and operate the means of production, and the prices of goods and services are determined by supply and demand in the marketplace. In simple terms, this means that people are free to produce and sell whatever they want, and consumers are free to buy whatever they want, at prices that are determined by the market. This creates an economy that is driven by competition and innovation, and is often associated with growth and prosperity. It is important to note that capitalism can take on different forms, ranging from a more laissez-faire approach with minimal government intervention, to a more regulated form with a larger role for the government in managing the economy.
Question 32 Report
The release of a liquid petroleum hydrocarbon into the environment is_______
Answer Details
An oil spill is the release of a liquid petroleum hydrocarbon into the environment. This can occur in a variety of ways, such as from an oil tanker that leaks or a pipeline that ruptures. The oil can contaminate the water and harm wildlife, as well as damage the natural environment and disrupt human activities such as fishing and tourism. It is important to take measures to prevent and clean up oil spills to minimize their impact on the environment and local communities.
Question 33 Report
Consider the diagram below which shows a demand curve (d).
Total expenditure on a commodity is represented by the area TUVW. Consumer's surplus is represented by__________
Answer Details
Consumer's surplus is represented by the area above the demand curve and below the market price. In the diagram, this would be the area represented by VWX. Consumer's surplus measures the difference between the amount that consumers are willing to pay for a good and the amount they actually pay. In the diagram, consumers are willing to pay more for the good up to the market price, represented by the height of the demand curve. The area VWX represents the amount by which they are benefiting from the market, as they are paying less than they would be willing to pay. So, the answer to the question is the area VWX represents consumer's surplus.
Question 34 Report
A contractionary monetary policy is used to control__________
Answer Details
A contractionary monetary policy is used to control inflation. Inflation is a sustained increase in the general price level of goods and services in an economy over time. It occurs when there is too much money chasing too few goods, leading to an increase in demand and upward pressure on prices. A contractionary monetary policy is a type of economic policy used by central banks to reduce the money supply and increase the cost of borrowing, with the aim of slowing down the economy and reducing inflationary pressures. This can be achieved through several measures, such as raising interest rates, increasing reserve requirements for banks, and selling government securities in the open market. By reducing the supply of money and making it more expensive to borrow, the central bank aims to reduce spending and investment in the economy, which can help to lower inflation. A contractionary monetary policy is the opposite of an expansionary monetary policy, which is used to stimulate economic growth by increasing the money supply and lowering interest rates.
Question 35 Report
The last link in the channel of distribution is____________
Answer Details
The last link in the channel of distribution is the Consumer. The channel of distribution refers to the path that a product takes from the producer to the final customer. The producer creates the product, and it is then sold to a wholesaler, who sells it to a retailer, and finally, the retailer sells it to the consumer. The consumer is the end user of the product and is the last link in the chain of distribution. In other words, the consumer is the person who ultimately buys the product and uses it for their own purposes. The channel of distribution is important because it helps to ensure that the product reaches the end user in a timely and efficient manner.
Question 36 Report
In a perfect competition, the market price is determined by_______
Answer Details
In a perfect competition, the market price is determined by the market supply and demand junctions. This means that the price is set by the intersection of the supply of goods and services offered by producers and the demand for those goods and services by consumers. When there is a high demand for a good or service, the price will go up, and when there is a low demand, the price will go down. This is because producers will raise their prices when there is high demand in order to make more profit, and they will lower their prices when there is low demand to try to sell more goods. On the other hand, consumers will be willing to pay more for a good or service when there is high demand and they will be less willing to pay when there is low demand. The market price is a result of the negotiation between producers and consumers, and it reflects the balance between supply and demand in the market.
Question 37 Report
The demand for labour is a________
Answer Details
The demand for labor is a "derived demand". This means that the demand for labor is not a direct demand for labor itself, but rather it is derived from the demand for goods and services that labor can produce. In other words, businesses hire workers because they need them to produce the goods and services that they sell. For example, if a business sells pizzas, it will need workers to make the pizzas, deliver the pizzas, and serve the customers. The demand for labor in this case is derived from the demand for pizzas. If the demand for pizzas increases, the demand for labor to produce and deliver the pizzas will also increase. Therefore, the demand for labor is closely tied to the demand for the goods and services that labor produces, and it is derived from that demand.

Answer Details
Question 39 Report
Effective demand for a commodity is desire for that commodity backed by_______
Answer Details
Effective demand for a commodity is the desire or want for that commodity backed by the ability and willingness to pay for it. This means that a person not only wants the commodity, but also has the means to purchase it and is willing to part with their money in exchange for it. For example, if someone wants to buy a new car but does not have the money to pay for it, their desire for the car is not effective demand. Similarly, if someone has the money but is not interested in buying a car, their willingness to pay is not effective demand. Effective demand requires both the desire for the commodity and the ability and willingness to pay for it. It is the combination of these two factors that drives the demand for goods and services in the economy.
Question 40 Report
The determination of wages in a labour market depends on the_______
Answer Details
The determination of wages in a labor market depends on the interaction between the demand for and supply of labor. In simple terms, employers demand labor to produce goods and services, while workers supply their labor to earn wages. The wage rate is then determined by the equilibrium point where the demand for labor meets the supply of labor in the market. When there is a high demand for labor and a low supply, wages tend to increase because employers are competing for a limited number of workers. On the other hand, when there is a low demand for labor and a high supply, wages tend to decrease because there are more workers than jobs available. Other factors such as government policies, economic conditions, and the skills and qualifications of workers can also influence the wage rate, but the main determinant is the interaction between the demand for and supply of labor in the market.
