Which option gives the correct cause-effect relation between population growth and service capacity?

Correct answer: If population grows faster than services, pressure rises

The correct answer is A. Service capacity means the number of people that schools, hospitals, water systems, transport, housing, and other facilities can adequately support. Step by step, population growth increases demand for these services. If facilities expand at the same pace, demand and capacity can remain more balanced. If population grows faster than capacity, more people must share the same classrooms, hospital beds, water supply, roads, or homes. This can cause overcrowding, longer waiting times, shortages, and pressure on public systems. Option B is wrong because a larger population usually increases service needs. Option C is wrong because population size directly affects demand. Option D is wrong because slow capacity expansion can create shortages, not always benefits. Memory cue: faster demand growth than supply creates pressure.
