Question

What happened when farmers "drastically altered" the breeding zones of the rocky mountain locusts?

1) The locusts migrated to a different region.
2) The locusts became extinct.
3) The locusts multiplied rapidly.
4) The locusts changed their feeding habits.

Answer 1

Altering the breeding zones of the rocky mountain locusts by farming activities led to their extinction as their natural habitats were destroyed.

Step-by-step explanation:

When farmers "drastically altered" the breeding zones of the rocky mountain locusts, the locusts became extinct. This is attributed to the changes in the ecosystem caused by farming activities such as plowing and irrigation, which destroyed the natural habitat of these locates in the plains and river valleys where they thrived. These human activities interfered with the locusts' life cycle, leading to their extinction by the early 1900s. Environmental pressures such as these have repeatedly demonstrated their potential to alter insect populations and even lead to the disappearance of species.
