Which of the following measurements, if subsequently completed, would provide data to explain the researchers' result?

A) Measure the number of ant females.
B) Measure the relative sizes of the treehoppers.
C) Measure the relative abundance of jumping spiders.
D) Measure the relative sizes of different ant species.
