Question

setting fires in a forest is sometimes used to ______
which phrase best completes the sentence?

• relocate wildlife to other areas
• protect the underbrush from larger fires
• protect the larger trees from larger fires
• kill weaker trees

Explanation:

Controlled forest fires (prescribed burns) are used to clear underbrush, which removes fuel for large, destructive wildfires. This protects mature, larger trees by reducing the risk of intense fires that can harm them. The other options are incorrect: prescribed burns do not relocate wildlife, do not protect underbrush (they remove it), and are not targeted at killing weaker trees as a primary goal.

Answer:

protect the larger trees from larger fires
