Question

what was the purpose of building crossing structures for pronghorn? this question is worth 2 point(s) to train pronghorn for migration. to provide shelter for animals during winter. to keep animals away from human settlements. to help animals cross safely and avoid being hit by vehicles.

Explanation:

Crossing structures are built to ensure the safety of animals like Pronghorn. They allow animals to move across areas (such as roads) without the risk of being struck by vehicles. This is a common practice in wildlife - conservation and management to maintain animal migration routes and overall population health. Training for migration is not the main purpose as animals have natural migratory instincts. Shelters for winter are usually different structures (like barns for domesticated animals in some cases, but not crossing structures). Keeping away from human settlements is not the key function as crossing structures are about safe passage rather than isolation from humans.

Answer:

To help animals cross safely and avoid being hit by vehicles.
