the presence of abundant natural resources.
strong environmental regulations.
access to ports for water transportation.

1. what challenge has been created by maquiladoras in mexican border towns?

a decrease in job opportunities
a decrease in manufacturing jobs in central america
an increase in tourism
housing shortages and strain on infrastructure

Explanation:

For the first question: Maquiladoras are foreign-owned factories in Mexico near the US border, focused on assembling goods for export to the US. Proximity to the US cuts transport costs and enables easy export. Abundant natural resources are not their key draw, strong environmental regulations would deter them, and access to ports is not the primary reason for their border location.
For the second question: Maquiladoras bring a large influx of workers to border towns quickly. This sudden population growth outpaces the development of housing and public infrastructure, leading to shortages and strain. They increase job opportunities, do not decrease Central American manufacturing jobs directly, and are not linked to increased tourism.

Answer:

First question: Location near the United States for easy export.
Second question: Housing shortages and strain on infrastructure
