题目：
Normally, the pineal gland governs a person’s sleep-wake cycle by secreting melatonin in response to the daily cycle of light and darkness as detected by the eye. Nonetheless, many people who are totally blind due to lesions in the visual cortex of the brain easily maintain a 24-hour sleep-wake cycle. So the neural pathway by which the pineal gland receives information from the eye probably does not pass through the visual cortex.
For purposes of evaluating the argument it would be most useful to establish which of the following?
For purposes of evaluating the argument it would be most useful to establish which of the following?
选项:
A、Whether melatonin supplements help people who have difficulty maintaining a 24-hour sleep cycle to establish such a pattern
B、Whether the melatonin levels of most totally blind people who successfully maintain a 24-hour sleep-wake cycle change in response to changes in exposure to light and darkness
C、Whether melatonin is the only substance secreted by the pineal gland
D、Whether most people who do not have a 24-hour sleep-wake cycle nevertheless have a cycle of consistent duration
E、Whether there are any people with normal vision whose melatonin levels respond abnormally to periods of light and darkness

提问：
想问英吉老师一个问题，希望他可以作答。我对本题理解是，d和e，一个说不能维持24小时周期的人，一个说看得见的人，但原文围绕的是能维持24小时周期瞎子说的，所以d和e可以杀掉。但是我觉得这么做不太对，因为英老师课上说，一种支持方法是说它的一个对立面不好，进而反向加强了它的推论。选项说到了瞎子的对立面，就是看得见的人，是不是也不一定错呢？超出原文范围和说它的对立面，我总是容易混淆，请老师帮忙
