The correct responses that encourage Mexican workers to come to the United States and how these workers affect Mexico's economy are:
- Many of these workers send money home to family members in Mexico.
- Mexican workers sometimes leave Mexico to find better work opportunities.
The other statements are misleading or incorrect. The migration of workers does not lead to a complete decline in Mexico's agricultural sector, and the motivations for migration are typically related to employment opportunities rather than investment in American real estate or escaping tropical weather conditions.
