Quizplus · Accepted Answer

The second researcher is addressing the problem of external validity, which refers to the ability to generalize research findings to a wider population or real-world settings. The first researcher conducted the study on rats, and there is a question of whether the findings will apply to humans with Alzheimer's disease. The second researcher is addressing this issue by testing the medication on humans with Alzheimer's disease to see if the effects generalize to this population.
