Answer:
The control group is the 15 young hemlocks trees with fencing around them to prevent deer from eating them.
Explanation:
An experiment is designed to test one or more hypotheses. For that, you need control and treatment groups. The control group is the non-effect group, it is the one from which you compare results from the treatment group. On the other hand, the treatment group is the effect group, it is the one that will be exposed to the "thing" that you want to test the effect of. Because you want to evaluate the impact of deers on the young hemlocks trees, the control should exclude deers.
In this case:
Hypothesis: Because deers eat young hemlocks trees and the population of deer had doubled in the last five years, the mature hemlocks trees are more abundant than the young hemlocks trees.
Control: group of 15 young hemlocks trees with fencing around them to prevent deer from eating them.
Treatment: a group of 15 young hemlocks trees with no fencing around them to permit deer eating them.
