Question 1 Report
The diagram shows a waste-management system proposed for a medium-sized city in Costa Rica. Household waste is separated at a collection point before different materials are sent to a recycling centre, compost facility or landfill. The council wants to reduce the amount of waste buried in landfill each year.
(a) State the destination for food scraps in Fig. 1. [1]
(b) State two environmental advantages of recycling materials rather than sending them to landfill. [2]
A city transport officer used Fig. 1 to explain a proposed bus rapid transit route in Dar es Salaam. Buses would have a lane separated from general traffic for much of the route. The plan links a high-density housing area to the CBD and to a market where many commuters work or trade.
(a) State the type of transport shown by the central route. [1]
(b) State two ways this scheme could reduce traffic congestion. [2]
Answer Details
Waste management
(a) Food scraps should be sent to the compost facility. [1]
(b) Recycling conserves raw materials because fewer new resources need to be extracted. It also reduces the amount sent to landfill, which can reduce methane emissions and pollution from waste disposal. It may also use less energy than manufacturing products from new materials. Any two valid advantages gain credit. [2]
Bus rapid transit
(a) The route is bus rapid transit, a form of public bus transport. [1]
(b) The scheme can encourage commuters to leave cars at home and carry many passengers in one vehicle. Its dedicated lane avoids delays caused by general traffic, making buses a more reliable alternative to driving. Any two valid points gain credit. [2]
