Question

as humans have spread over the landscape, we have invaded the natural habitats of wildlife. highways and roads in particular form barriers preventing wildlife from reaching other parts of their ecosystem. when animals have to cross a highway, they risk being hit by cars and trucks. this is a dangerous situation not only for the animals, but for the people driving as well. one way engineers are combating this danger is by creating overpasses or underpasses for wildlife along their habitual migration paths. what do you think about wildlife overpasses and underpasses? this is a really great idea! how do the animals know to use the overpass?

Explanation:

Wildlife overpasses and under - passes help connect fragmented habitats and reduce animal - vehicle collisions. The first option shows a positive view of this solution, while the second option raises a valid concern about animal behavior and their ability to utilize these structures.

Answer:

Both responses have merit. The first response, "This is a really great idea!" acknowledges the positive aspects of wildlife overpasses and under - passes in mitigating the negative impacts of human infrastructure on wildlife. The second response, "How do the animals know to use the overpass?" is a valid question regarding animal behavior and the effectiveness of these structures in practice.
