How do park officials plan to help save the hemlock trees?

A. They will plant more hemlock trees along the creek beds.
B. They will release beetles that feed on adelgids into the environment.
C. They will cover the trees with a white woolly substance to protect them.
D. They will use needles to pump more sap into the trees.

To find the answer to this question, you can start by conducting a search using keywords such as "park officials," "saving hemlock trees," and "conservation efforts." The search results should provide you with information about specific measures taken by park officials to help save hemlock trees. It's important to rely on credible sources such as official park websites, environmental organizations, or scientific studies for accurate and up-to-date information.

Based on the available options, let's break down each choice to determine the most likely answer:

A. Planting more hemlock trees along the creek beds could be one possible strategy, but it may not be the primary focus of the park officials' conservation efforts.

B. Releasing beetles that feed on adelgids into the environment is a common method for controlling these harmful pests, which could be helpful in saving hemlock trees. Adelgids are aphid-like insects that feed on hemlocks and cause significant damage.

C. Covering the trees with a white woolly substance is not a widely known or practiced method for protecting hemlock trees.

D. Using needles to pump more sap into the trees is not a commonly recognized technique to save hemlock trees.

Based on this analysis, option B seems to be the most plausible choice. Releasing beetles that feed on adelgids into the environment is an effective strategy used by park officials and conservationists to combat the destructive impact of the adelgids on hemlock trees.
