Answer

Brief Explanations:

Plants on hillsides have root systems that hold soil in place. Removing them (either by removing plants in general or clearing trees) eliminates this anchoring effect, making soil more prone to sliding, which can lead to landslides. Human activities don't directly increase rain - storm frequency and they can increase fire risk in some cases. Also, human activities do impact landslides.

Answer:

A. Removing plants from hillsides eliminates the root structures that anchor soil. B. Clearing trees from hills increases the frequency of rainstorms. (Incorrect as human activities don't directly increase rain - storm frequency) C. Human activities tend to reduce the risk of fires. (Incorrect as human activities can increase fire risk in some cases) D. Landslides are not impacted by human activities. (Incorrect as human activities do impact landslides) So the answer is A.
