77,How do the airlines expect to prevent commercial planecrashes? Studies have shown that pilot error contributes to two-thirds of allsuch crashes. To address this problem, the airline have upgraded their trainingprograms by increasing the hours of classroom instruction and emphasizingcommunication skills in the cockpit. But it is unrealistic to expect suchmeasures to compensate for pilots’ lack of actual flying time. Therefore, theairlines should rethink their training approach to reducing commercial crashes.

Which one of the following is an assumption upon which theargument depends?

A.      Trainingprograms can eliminate pilot errors.

B.       Commercialpilot routinely undergo additional training throughout their careers.

C.       The numberof airline crashes will decrease if pilot training programs focus on increasingactual flying time.

D.      Lack ofactual flying time is an important contributor to pilot error in commercialplane crashes.

E.       Communicationskills are not important to pilot training programs.

参考答案：D

思路：xxx的program不能补充pilots’ lackof actual flying time.结论：thererfore,rethink approach to prevent commercial plane crash. 中间有思维跳跃，actualflying time 与plane crash 什么关系？

A.       削弱，programcan eliminate…, so do not need rethink approach

B.        无关。题中是preventplanes crashes的training.

C.        加强。

D.       将actual flyingtime 与(pilot error in) plane crashes 联系起来。对assumption取非：actualflying time is not an important contributor to pilot error in commercial planecrashes. 削弱结论。符合ETS假设定义。

E.        加强。

我的问题是: C选项,他给的解释说是加强,什么意思啊?加强了什么,为什么不能选?thanksss
