How did the environment of Arabia serve as a form of protection during much of the region's history?

A.Its fertile oases enabled farmers to grow enough food for themselves and for sale.

B.Its extreme heat and arid conditions kept invaders from attacking settlements.

C.Its landlocked location prevented traders from bringing in foreign goods.

D. Its mountainous regions kept farmers from Mesopotamia from moving in for better land.

B.Its extreme heat and arid conditions kept invaders from attacking settlements.

Does anybody know if they are correct?

B. Its extreme heat and arid conditions kept invaders from attacking settlements.

The correct answer is B. The extreme heat and arid conditions of the Arabian environment served as a form of protection during much of the region's history.

To arrive at this answer, let's go through the options one by one:

Option A suggests that fertile oases enabled farmers to grow enough food for themselves and for sale. While this statement is true, it does not directly relate to the protection provided by the environment.

Option C suggests that the landlocked location of Arabia prevented traders from bringing in foreign goods. However, Arabia has many coastal areas and was an important center for trade throughout history, so this option is incorrect.

Option D suggests that the mountainous regions of Arabia kept farmers from Mesopotamia from moving in for better land. While there are some mountainous regions in Arabia, they are not significant enough to have prevented farmers from Mesopotamia from moving in completely, so this option is also incorrect.

This leaves us with option B, which states that the extreme heat and arid conditions of the environment kept invaders from attacking settlements. This is the correct answer as the harsh desert climate, with its scorching heat and limited water sources, acted as a natural barrier, making it difficult for invaders to cross the desert and conduct successful military campaigns. This provided a level of protection to the region throughout its history.

So, the correct answer is B. Its extreme heat and arid conditions kept invaders from attacking settlements.
