Which river runs through Cairo?

Cairo, the capital city of Egypt, is situated on the banks of the Nile River, which is one of the longest rivers in the world. The Nile has been crucial for the development of Egyptian civilization for thousands of years, providing fertile land and a vital water source in an otherwise arid region. Its significance cannot be overstated, as it was essential for agriculture and transportation in ancient times and continues to be important for the economy and daily life in modern Egypt.

The other rivers listed do not flow through Cairo. The Amazon River is located in South America, primarily flowing through Brazil. The Yangtze River is found in China and is the longest river in Asia. The Mississippi River runs through the United States, primarily along its eastern side. Therefore, the only river that flows through Cairo is the Nile, making it the correct choice.
