Why did some colleges close during World War I?

A. Too many riots took place in protest of the war.
B. Women had to quit college to go to work.
C. Too many men had to serve in the war.
D. Funds were redistributed to support war efforts.

The correct answer is C. Too many men had to serve in the war. During World War I, many college-aged men were drafted or enlisted to serve in the military. As a result, colleges and universities saw a significant decline in enrollment and were forced to close or significantly reduce their operations. Some colleges also turned their facilities over to the military for use as training camps or hospitals.
