SAT Text Structure and Purpose Question

In 2016 Ana Filipa Lopes and colleagues published a study concluding that ocean acidification has a strong effect on the behavior of Atherina presbyter, a species of fish. However, Lopes and colleagues' study relied on a mean sample size of only about 15 fish. In a 2022 review of various scientists' conclusions about the impacts of ocean acidification on fish behavior, Timothy D. Clark and colleagues caution that relying on such a relatively small sample size can increase the potential for biased analysis. Such analysis, in turn, can contribute to reports of exaggerated effects. Which choice best states the main purpose of the text?
