E排除了他因的可能,那么就是支持了题目中说的因为缺少运动所以才导致chronic pain的结果.选项E就是说明有这样一种strategy可以减缓或者防止 a currently asymptomatic herniated or degenerated spinal disk疼痛发作．

Ｃ可是有一点无关的意思哦，病人在 that a spinal disk first becomes herniated or degenerated的时候suffer mild并不代表后来的变化状况。

23.  Chronic back pain is usually caused by a herniated or degenerated spinal disk. In most cases the disk will have been damaged years before chronic pain develops, and in fact an estimated one in five people over the age of 30 has a herniated or degenerated disk that shows no chronic symptoms. If chronic pain later develops in such a case, it is generally brought about by a deterioration of the abdominal and spinal muscles caused by insufficient exercise.

The statements above, if true, most strongly support which one of the following?

(A) Four out of five people over the age of 30 can be sure they will never develop chronic back pain.

(B) People who exercise their abdominal and spinal muscles regularly are sure to be free from chronic back pain.

(C) Patients rarely suffer even mild and fleeting back pain at the time that a spinal disk first becomes herniated or degenerated.

(D) Doctors can accurately predict which people who do not have chronic back pain will develop it in the future.

(E) There is a strategy that can be effective in delaying or preventing the onset of pain from a currently asymptomatic herniated or degenerated spinal disk.

請問一下,這一題答案是 E, 為什麼 c 不行？
