21. In response to high mortality in area hospitals, surgery was restricted to emergency procedures during a five-week period. Mortality in these hospitals was found to have fallen by nearly one-third during the period. The number of deaths rose again when elective surgery (surgery that can be postponed) was resumed. It can be concluded that ,before the five --week period, the risks of elective surgery had been incurred unnecessarily often in the area.

Which one of the following, if true, most seriously undermines the conclusion above?

(A) The conclusions for which elective surgery was performed would in the long run have been life-threatening, and surgery for them would have become riskier with time.

(B) The physicians planning elective surgery performed before the five-week period had fully informed the patients who would undergo it of the possible risks of the procedures.

(C) Before the suspension of elective surgery, surgical operations were performed in area hospitals at a higher rate, per thousand residents of the area, than was usual elsewhere.

(D) Elective surgery is, in general, less risky than is emergency surgery because the conditions requiring or indicating surgery are often less severe.

(E) Even if a surgical procedure is successful, the patient can die of a hospital-contracted infection with a bacterium that is resistant to antibiotic treatment.

答案是a
这题的大致意思我懂，是说原本只做五周内的小手术，所以呢死亡率就下降了，做了延长期限的手术之后呢，死亡率就上升了，是因为这个延长期限的手术是不必要的
削弱是因为这个延长期限的手术本身就很危险，很容易死人

可是里面的这个,before the five --week period放在这是什么意思啊，大家帮我看看

文章的结论是手术增加了不必要的风险
A的意思是说那些被选择来的手术的病人本来就是有生命危险的,而且会随时间的增加危险增加
