Quizplus · Accepted Answer

It is important to test elderly men and women for the effects of caffeine as it is a population that commonly consumes caffeine and may experience age-related cognitive decline. This study would provide insight into the potential benefits caffeine may have on cognitive function in the elderly. Testing pregnant women or teenagers would likely be unethical as there may be potential risks involved for these populations.
