Set Impact Limits Practice Test

A hiking trail is experiencing habitat loss because visitors step off the path and crush plants near a creek. Evidence: Rangers mapped two areas where the ground is bare and widened by about 1 meter compared with last year, and most damage is near a scenic overlook. Constraints: The park can install only 30 meters of fencing this season, and rangers can check the area only twice per week. The goal is to reduce plant damage while keeping the trail open. Trade-offs are required.

Which limit is most realistic given the context?

A farm is trying to reduce soil erosion (habitat loss and muddy runoff) into a nearby creek. Evidence: After heavy rains, the creek turns brown, and the farmer sees small gullies forming on a sloped field. Constraints: The farmer has only one weekend to install any changes before planting, and only enough straw to cover about half the slope. The goal is to reduce sediment reaching the creek while still planting the crop. Trade-offs are required.

Which claim ignores the limits in this situation?
