Question

what did not cause many immigrants to leave their native countries?
poverty
political unrest

Explanation:

Poverty often pushes people to seek better economic opportunities elsewhere, so it causes immigration. Political unrest creates an unstable and unsafe environment, leading people to leave. Crop failures lead to food shortages and economic hardship, prompting migration. Harsh climate, while it can impact life, is not a primary or common driver for large - scale immigration compared to the other three factors.
