One reason that best explains why certain areas of Southwest Asia have a low population density is the harsh and inhospitable environmental conditions in these regions. This includes extreme temperatures, lack of water sources, limited arable land for agriculture, and frequent droughts, making it difficult for people to settle and sustain a livelihood in these areas. Additionally, conflict and political instability in some parts of Southwest Asia can also contribute to low population density as people may be forced to flee or avoid settling in these areas.
