Question

Why do most people in the Sahara tend to live along the Nile River or the Mediterranean coast?
A.
because of the lack of available water resources in the region

B.
because most of the region's population works in the mining industry

C.
because the thick vegetation in the inland areas of the region limits development

D.
because there is no way to conduct trade in the region except via waterways

Answer 1

A. Because of the lack of available water resources in the region.

Most people cluster along the Nile and Mediterranean coast where water, fertile land, and more favorable climate allow agriculture, settlements, and trade — the interior Sahara is too arid for large populations.
