The only purpose for which a particular type of tape is needed is to hold certain surgical wounds closed for ten days—the maximum time such wounds need tape. Newtape is a new brand of this type of tape. Newtape’s salespeople claim that Newtape will improve healing because Newtape adheres twice as long as the currently used tape does.
Which of the following statements, if true, would most seriously call into question the claim made by Newtape’s salespeople?




(A) Most surgical wounds take about ten days to heal.

(B) Most surgical tape is purchased by hospitals and clinics rather than by individual surgeons.

(C) The currently used tape’s adhesiveness is more than sufficient to hold wounds closed for ten days.

(D) Neither Newtape nor the currently used tape adheres well to skin that has not been cleaned.（C）

(E) Newtape’s adhesion to skin that has been coated with a special chemical preparation is only half as good as the currently used tape’s adhesion to such coated skin.

C是weaken，能 理解，但E是不是weaken呢？Newtape’s salespeople claim that Newtape will improve healing ，E也是反对这句话的呀。

谢谢！

偶觉得e有两个地方与题目讲的不是一回事：skin不等同于wound,题目讲的是时间的长短，而e讲的是好坏，题目对时间的长短和好坏之间的关系并没有描述。

同意，E属于out of scope

E 的确是 out of scope, 楼主你想的太多了, 不要自己加什么assumption在里面, 如果文中说明了adhesion和coated skin 的重要性, 才去考虑E

我认为这个题目中有一个隐含假设就是OLD TYPE用的时间少于10天,所以说NEW TYPE可以比它用的时间长是好事.

问WEAKEN.

直接得出答案C,OLD TYPE已经足够用了,所以用NEW TYPE就多余了。

我是这样理解的，New贴的时间是currently的那种两倍长，而作用只有currently的一半，那其实整体作用不就差不多，也就谈不上improve healing
