I think the correct answer should be D.
B can not be inferred from the passage. Lower level of serotonin might not be the only cause of depression. Lack of sunlight might cause something else which in turn causes depression.
E is not correct as Seronotin is only one type of neurotransmitters. So raising this particular type of neurotransmitter, as indicated by the passage, will boost mood. We can not infer that raising other neurotransmitters will do the same.
Please double check the answer and confirm.作者: gu946 时间: 2003-7-11 13:50
