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?
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
答案:
B
提问：
根据最后一句得知:neural的路径可能不会路过视觉的cortex. 如果只看最后一句与下面的选项就完全搭不上边，所以读了题干所有的句子，然后就有点乱在说啥，选项判断不出来哪个有关。
