The Hemlock Woolly Adelgid is an insect that has accidentally been released in Eastern U. S. forests from Asia. Since it has no natural enemies in the U. S., it is spreading rapidly. A forester studying the abundance of the insect in southern Vermont wants to determine if it has spread that far north. He randomly selects 200 hemlock trees in a large Vermont forest and finds that 46 of them show signs of damage from this insect. To which of the following groups of trees would it be appropriate to generalize the results of the study?
A. All hemlock trees in southern Vermont
B. All trees in southern Vermont
C. The 200 hemlock trees that were randomly selected
D. All hemlock trees in the U. S.
E. All hemlock trees in the forest from which the 200 trees were selected
