At which capital do the Blue Nile and the White Nile combine to form the Nile?

• A. Khartoum
• B. Cairo
• C. Lagos
• D. Juba

Answer: (A)

The correct answer is Khartoum because it is the city where the Blue Nile and the White Nile converge to form the Nile River. The Blue Nile originates from Lake Tana in Ethiopia and flows north, while the White Nile flows north from Lake Victoria. Their meeting point is significant both geographically and historically, as the Nile is the longest river in the world and has been crucial to the civilizations that developed along its banks.

Cairo is located further downstream, where the Nile flows through Egypt, but the confluence happens before it reaches this city. Lagos, on the other hand, is located in Nigeria and is not associated with the Nile River. Juba serves as the capital of South Sudan and is located along the White Nile but does not represent the convergence point of the two major tributaries. Thus, Khartoum is the key location for this important geographical event in the Nile River system.
