Answer 1

The reason that best explains why certain areas of southwest Asia have low population density is:

The semi-arid climate makes farming difficult because it produces very little rainfall.

This lack of rainfall limits agricultural opportunities, which in turn affects the population density, as people tend to settle in areas where farming and other economic activities can be sustained.
