a. california
b. canada
c. pennsylvania
d. florida

A California.

Explanation:

In the 1920s in California, the term (often used in contempt) came to refer to very poor migrants from Oklahoma (and nearby states). The Dust Bowl and the "Okie" migration of the 1930s brought in over a million newly displaced people; many headed to the farm labor jobs advertised in California's Central Valley.

nothing certain is known about what happened, but it seems that the country declined gradually, perhaps due to bad government, or, more likely, due to a series of bad harvests, which resulted in widespread and recurrent famine.
