Answer 1

Since much of the Middle East is desert, most population centres are along river system.

Step-by-step explanation:

• The characteristics of the Middle East of the presence of negligible vegetation and the existence of barren sandy lands tends to make it a dry and hot desert with a large expanse.
• As the Middle East faces the greatest scarcity of water than any other part of the world, the populations here prefer settling down only in close proximity to rivers.
