Which reason best explains why certain areas of southwest Asia have low population density?
A.The semi arid climate makes farming difficult because it produces very little rainfall.
B. The moist climate limits job opportunities because it reduces oil production.
C. The semi arid climate produces heavy rainfall that contributes to devastating floods.
D. The most climate reduces agricultural production by causing water shortages.
The reason that best explains why certain areas of southwest Asia have low population density is option D: The moist climate reduces agricultural production by causing water shortages.
To arrive at this answer, let's analyze the given options one by one:
Option A states that the semi-arid climate in southwest Asia makes farming difficult due to very little rainfall. While this may be a challenge for agriculture, it does not directly relate to population density.
Option B suggests that the moist climate in southwest Asia limits job opportunities by reducing oil production. While oil production is indeed an important economic factor in this region, it doesn't directly explain the low population density.
Option C states that the semi-arid climate produces heavy rainfall that contributes to devastating floods. While heavy rainfall and floods can have an impact on agriculture and infrastructure, it does not specifically address the low population density.
Option D suggests that the moist climate reduces agricultural production by causing water shortages. This option directly explains why certain areas in southwest Asia have low population density. Water scarcity is a significant challenge for agriculture, and when agricultural opportunities are limited, people are less likely to settle in those areas, leading to low population density.
Therefore, the most reasonable explanation for the low population density in certain areas of southwest Asia is option D: The moist climate reduces agricultural production by causing water shortages.
