Population Distribution Practice Test

A secondary source describing global population patterns states that settlement is often clustered rather than evenly dispersed. The source cites examples such as river deltas, coastal plains, and transportation hubs where economic opportunities concentrate, producing dense settlement corridors. Which choice best identifies the spatial pattern described?

A secondary source on population distribution explains that people tend to cluster in environments with reliable freshwater, moderate climates, fertile soils, and accessible terrain. It contrasts these areas with deserts, dense rainforests, and high mountains, where settlement is more difficult and costly. Which factor-based explanation best matches the source?
