Question

Quizplus · Accepted Answer

The hypothesis being tested is that industrial melanism (the darkening of the skin or fur of a species to better blend in with polluted environments) could cause changes in moth coloring. Therefore, to test this hypothesis, the tree trunks can be darkened to mimic the pollution that leads to industrial melanism in the first place. The other options do not directly test the hypothesis and could potentially disrupt the controlled environment of the experiment.
