参考答案

正确答案：C
解析：本题考察推理能力，问“医生的睡眠问题暗示了什么”。短文第二段“…in the morning after 24hours of sleeplessness，a person’s motor performance is comparable to that of someone who is legallyintoxicated．Curiously，surgeons who believe that operating under the influence is grounds for dismissal often don’t think twice about operating without enough sleep．”也就是说医生们虽然认为醉酒开刀应该受到严惩，但对于在睡眠不足的情况下做手术却并不加以认真考虑。由此可见。“医生们大都忽略了他们自己的睡眠问题”。
