select the correct answer from each drop - down menu.
the death rate decreased after the 1950s because medical care improved in several nations. also began dropping dramatically.
wars
infant mortality
food production

Explanation:

Improved medical care is a direct factor reducing death rates. Wars, by contrast, typically increase mortality through conflict-related deaths, so a drop in wars would contribute to a lower death rate. Infant mortality is a component of death rate (not a separate factor that "drops" to reduce overall death rate), and food production improvement would support lower death rates but is not listed as needing a "drop"—the blank requires a factor that decreased to reduce death rates, making Wars the correct choice.

Answer:

Wars
