and farming. Conscientious objectors filled those roles. In addition, although
they didn't fight, some of these men nonetheless risked their lives as test
subjects in starvation experiments. Their work helped nutritionists
understand how to restore people to health after the devastation of the war in
Europe. Which of the following is an effective summary of this paragraph?
A. The United States suffered from a lack of manpower on the home

B. The United States allows an exception to the military draft,
C. Nutritionists working in Europe after World War II benefited from
the work of conscientious objectors.
