Complete Question Explanation
Resolve the ParadoxX. The correct answer choice is (B)
This stimulus describes the study of a particular community’s elderly. For some reason, those elderly who moved to the community in the last five years are healthier than those elderly who spent their lives in the community. A resolution would help to explain why the health of one group is better than that of the other. Because this is a ResolveX question, the four incorrect answer choices will provide some resolution, and the correct answer choice will not.
Answer choice (A): This answer choice would provide some explanation for the disparity in general health between the two groups. The group of movers was a self-selecting sample—they all chose to move. If those with the means to relocate tend to be in better health, this would explain why we would expect the group who had moved to be healthier as a group than those who had lived in the community for their whole lives (based on the information presented in the stimulus, there is no way to assess whether or not any of the life-long residents have the means to relocate).
Answer choice (B): This is the correct answer choice to this ResolveX question, because it is the one which fails to provide an explanation for the difference in health between the two groups. The stimulus deals only with two groups of elderly, so the proportions of young versus elderly do not come into play.
Answer choice (C): Like incorrect answer choice (A) above, this choice would also help to explain why the elderly who had lived in the community for longer might be expected to be in worse physical health (having dealt with low-quality health care for their entire lives), than those who have lived in the community for five years or less, having had access to potentially better quality health care.
Answer choice (D): If changing one’s environment tends to be beneficial, then this would help to explain why the elderly who had had such a change in the last five years might have reason to expect better health in general than those had live in the community for their entire lives.
Answer choice (E): This choice would help to explain why those recent movers are in better health as a group, in much the same way as answer choice (A) above. This was a self-selecting sample—that is, this group is comprised of people who were able to move. The same cannot be said for the elderly who lived in the community for their entire lives. Since this provides some resolution to the paradox, it is one of four incorrect answer choices to this ResolveX question.
