Chantelle notes that the HIV/AIDS epidemic contributes to food shortages in some countries. Why might this be the case?

a. HIV-infected food passes on the virus.

b. Money that could be spent on food is spent on medications.

c. The virus kills many working-age adults who might otherwise contribute to food production.

d. The epidemic pushes scientists out of those countries into nations where they can conduct food research without worrying about it.

e. The epidemic has sparked a general strike throughout many of these nations, which has contributed to a lack of harvesting.
