Which pressure can increase in urban areas due to population growth?

Correct answer: Pressure on housing, transport, and water services

Direct answer: A is correct. When the population of a city grows, more people need homes, roads, public transport, drinking water, drainage, electricity, schools, and health services. If these facilities do not expand at the same pace, existing systems become overcrowded and service pressure increases. A is therefore a realistic and direct urban effect of population growth. B is wrong because population growth does not normally change the depth of the sea. C is wrong because the number of city residents does not determine the height of mountains. D is wrong because moonlight is not an urban service whose supply is used up by people. The question asks about pressure on services, so focus on facilities that cities must plan and provide. Memory cue: more urban residents mean greater demand for houses, movement, and basic services.
