"The removal of native prairie plants" contributed to the Dust Bowl of the 1930s.
Option: B
Explanation:
The time of extreme dust storms that severely damaged prairie ecosystems and agriculture in American and Canadian states throughout the 1930s is known as "Dust Bowl". It brought massive drought and inability to implement dryland farming practices to discourage aeolian mechanisms exacerbated the occurrence.
Every year the farming process starts with the preparation of the soil for seeding. But farmers had plowed the soil too fine for years, so they helped to create the Dust Bowl. In fall 1939, rain eventually returned to many parts of the Great Plains in considerable amounts, marking the end of the Dust Bowl.
