這一題CR題,看不太懂~麻煩各位了!

Although the surge in consumer spending over the last two years has mostly benefited foreign companies as Uniter States consumers purchased imported products, some United States service industries have benefited as well. Payments to medical doctors, for example, have increased significantly in the past year after a lengthy lull.

Which of the following, if true, would most weaken the authou's assertion that the medical doctors have benefited from the recent surge in consumer spending?

A) Consumers of medical care in the United States tend to postpone treatment for minor medical problems during periods of economic recession.

B) Increases in the cost of malpractice insurance have required doctors to increase their fees accordingly.

C) Preventive measures against catastrophic illnesses such as heart disease have generally improved the health of United States consumers.

D) The number of nonprofit, publicly owned hospitals in the United States has increased over the last year.

E) The average propotion of each medical bill paid by individuals rather than by medical insurance has decreased over the last year.

以上就是 我有問題的題目!  我看了很久  還是找不出這題的因果關係! 所以~ 拜託了!!

這題的解答是 B...  麻煩各位了~~謝謝~~ 

consumer spending↑
        
----> 果(1)foreign companies↑
----> 果(2)some US service industries ex: Payments
to medical doctors↑

问weaken，这题的考法是找出他因来否定掉
        

A) 有点暗示消费者景气不好不想去看小病，所以一直等到景气好时去看，所以医生所赚的钱才会增加。(我觉得有可能咩，不知怎样排除><)

B) 因为医疗不当，所以医生要支付的保险费用提高，因此相对医生对病人收的费用也调高

C) 提到太特定疾病，变成讨论子集合，所以删

D) 医院的增加，不代表医生收入有增加

E) 只是讲费用的百分比的消长，并不是说总额，所以删

PS:我修改因果关系图，让后人方便观看

謝謝囉~

不過針對答案A啊! 我後來再仔細想想! 題目的本意應該是 因為美國的消費者大量採購進口產品,導致國內的服務產業也跟著受 因為美國的消費者大量採購進口產品,導致國內的服務產業也跟著受惠. 接著 再舉醫院為例子!

因此 我認為 答案(A)選項 有偏離主題的嫌疑! 因為跟景氣搭不上關係! 不知道您覺得呢?

哈，这个题的意思是：进口增长(consumer spending) has relationship with service industry. so to weaken,you have to cut the relationship.that mean you have to find the anwer which anwers the service industry is due to other reason than consumer spending.Therefore the answer is B.

因为题目用if true，也就是不用怀疑这选项，当作可以讨论来看。后来我在想想A选项只讲人们延后看医，只有说明a
lengthy lull的情况，但是没有说现在人有跑去看病。

我之所以认为会有关系是因为如果人们过去一段时间不看病，而在景气好时去看医生，所以收入才增加。这是当初我没有办法排除的原因。

请指教

那，你的A选项本身就有IMPLIED PREMISE,就是1, 现在诊费价格不变，2,延后看病的病人造成多的出诊次。P*Q=S  所以造成现在医生收入多，对吧？

但是根据ETS的习惯，所以选项必须是清楚的，一目了然的，没有隐含的在里面。必须要把所有要说的都说清楚。你再看看B中直接讲FEE,是多么清楚。而如果你选A，就默认了要承认你脑袋里隐含的前提。怎么去保证他人能和你默想的前提一致呢？要记住凡是没有提到的不要扩展开你的思维。

明白？
