Which situation was not an effect of the Dust Bowl?
A. Crops and livestock were lost.
B. Storms caused widespread property damage.
C. Many people faced health problems.
D. Migration to Oklahoma increased.

D) Migration to Oklahoma increased

This is false because people left Oklahoma for places like California in search of work. The dust storms caused crops and livestock to be lost, and farmers lost their livelihoods and farms in part of it. Another factor was the depression that made prices too low, causing many people to become homeless and starve. The dust storms created many health problems as well. So this is why choices A, B and C are effects of the Dust Bowl, while choice D is not.
