Lorenzo Oconnor · Answer 1

The correct answer for this question is D - the best way to describe the purpose of a control sample is to compare its results to those of the experimental sample. The control sample is compared to the results in which the independent variable was changed, which therefore allows a scientist to better understand the effect of the independent variable.
