.
A. contains most of the evidence of humanity's African origins.
B. doesn't border the Sahara Desert.
C. is linked to Egypt by the Nile.
D. is politically distinct from other regional countries.
C?
Most of the maps showing sub-Saharan Africa include Sudan.
The correct answer is B. Sudan is omitted from inclusion in the sub-Saharan region because it doesn't border the Sahara Desert. To understand why, we need to look at the definition of the sub-Saharan region and its geographical boundaries.
The sub-Saharan region refers to the part of Africa that lies south of the Sahara Desert. Geographically, the Sahara Desert acts as a natural barrier, separating the countries in North Africa from those in sub-Saharan Africa.
Sudan, on the other hand, is located in North Africa, bordering Egypt to the north. While Sudan is considered part of the continent of Africa, it is not included in the sub-Saharan region because it does not lie south of the Sahara Desert.
Option C, which states that Sudan is linked to Egypt by the Nile, is not the reason why Sudan is omitted from the sub-Saharan region. The Nile River does indeed connect Sudan with Egypt, but the boundary between the sub-Saharan region and North Africa is defined by the Sahara Desert, not the river.
Therefore, the correct answer is B. Sudan doesn't border the Sahara Desert, and that is why it is omitted from inclusion in the sub-Saharan region.
