PrepTest 60, Section 2, Question 9
In one study of a particular plant species, 70 percent of the plants studied were reported as having patterned stems. In a second study, which covered approximately the same geographical area, only 40 percent of the plants of that species were reported as having patterned stems.

Which one of the following, if true, most helps to resolve the apparent discrepancy described above?
The first study was carried out at the time of year when plants of the species are at their most populous.
The first study, but not the second study, also collected information about patterned stems in other plant species.
The second study included approximately 15�percent more individual plants than the first study did.
The first study used a broader definition of "patterned."
The focus of the second study was patterned stems, while the first study collected information about patterned stems only as a secondary goal.
