In 2016Marta S. Pimentel and colleagues published a study concluding that ocean acidification has a strong effect on the behavior of Sparus aurata, a species of fish. However, Pimentel and colleagues' study relied on a mean sample size of only 12 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. What does the text most directly suggest about Pimentel and colleagues'conclusion?
