Question

why were the british so eager to control egypt after world war i?
they wanted to control the suez canal
they had the most powerful armed forces.
they had plans to install a vast irrigation system in the desert.
they wanted to protect the treasures in the pyramids.

Explanation:

The Suez Canal was a crucial waterway for British trade and military movements. Controlling it was vital for maintaining their global influence and access to resources. The other options are not the main reasons for British eagerness to control Egypt post - World War I. Having powerful armed forces was a means rather than the reason for control. Installing an irrigation system in the desert was not a significant factor in their eagerness to control the whole country. Protecting pyramid treasures was not a driving force for such a major geopolitical move.

Answer:

They wanted to control the Suez Canal.
