两道不懂 求NN解答GWD-9-Q37:

Researchers took a group of teenagers who had never smoked and for one year tracked whether they took up smoking and how their mental health changed. Those who began smoking within a month of the study’s start were four times as likely to be depressed at the study’s end than those who did not begin smoking. Since nicotine in cigarettes changes brain chemistry, perhaps thereby affecting mood, it is likely that smoking contributes to depression in teenagers.

Which of the following, if true, most strengthens the argument?

A. Participants who were depressed at the study’s start were no more likely to be smokers at the study’s end than those who were not depressed.

B. Participants who began smoking within a month of the study’s start were no more likely than those who began midway through to have quit smoking by the study’s end.

C. Few, if any, of the participants in the study were friends or relatives of other participants.

D. Some participants entered and emerged from a period of depression within the year of the study.

E. The researchers did not track use of alcohol by the teenagers.
答案选A，解释是说因果倒置，脑子转不过来，令不清了伐。

GWD-9-Q40:

Agricultural societies cannot exist without staple crops. Several food plants, such as kola and okra, are known to have been domesticated in western Africa, but they are all supplemental, not staple, foods. All the recorded staple crops grown in western Africa were introduced from elsewhere, beginning, at some unknown date, with rice and yams. Therefore, discovering when rice and yams were introduced into western Africa would establish the earliest date at which agricultural societies could have arisen there.

Which of the following is an assumption on which the argument depends?

A. People in western Africa did not develop staple crops that they stopped cultivating once rice and yams were introduced.

B. There are no plants native to western Africa that, if domesticated, could serve as staple food crops.

C. Rice and yams were grown as staple crops by the earliest agricultural societies outside of western Africa.

D. Kola and okra are better suited to growing conditions in western Africa than domesticated rice and yams are.

E. Kola and okra were domesticated in western Africa before rice and yams were introduced there.

这道题我用了取非削弱来看，可还是不太理解，选A

九段泡面高手

第一题：A选项说本来就抑郁的人不会比任何人更有学抽烟的倾向！这就保证了人们是因为抽烟才抑郁的（这就是题目想支持的 尼古丁 影响抑郁），排除了 “因为抑郁才去抽烟” 这个可能性。

第二个我记得我以前选对了，但是今天读完我也迷糊了??

GWD错7个多么??那看来我真的很弱了??算了算了，看来我verbal撑死也只有38的烂水平
