4. GWD21-Q4:

Which of the following most logically completes the passage?

Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed.  The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases.  A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses.  Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since ______.

1. the patients who are correctly diagnosed with this test as not having appendicitis invariably have medical conditions that are much less serious than appendicitis
2. the misdiagnoses produced by this test are always instances of attributing appendicitis to someone who does not, in fact, have it

3. all of the patients who are diagnosed with this test as having appendicitis do, in fact, have appendicitis

4. every patient who is diagnosed with this test as having appendicitis has more than one of the symptoms generally associated with appendicitis
5. the only patients who are misdiagnosed using this test are patients who lack one or more of the symptoms that are generally associated with appendicitis

为什么答案是B呢？谢谢

In the argument given, the two boldfaced portions play which of the following roles?

1. The first summarizes the evidence used in the reasoning called into question by the argument; the second states the counterevidence on which the argument relies.

2. The first summarizes the evidence used in the reasoning called into question by the argument; the second is an intermediate conclusion supported by that evidence.
3. The first is an intermediate conclusion that forms part of the reasoning called into question by the argument; the second is evidence that undermines the support for this intermediate conclusion.
4. The first is an intermediate conclusion that forms part of the reasoning called into question by the argument; the second is the main conclusion of the argument.

5. The first is an intermediate conclusion that forms part of the reasoning called into question by the argument; the second states a further conclusion supported by this intermediate conclusion.

答案AD哪个更好呢？谢谢

4. GWD21-Q4:

B) 被误诊断为有盲肠炎的病人实际上没有盲肠炎（于是刀下多了几条冤魂～～手术量比实际量要高）

C) 被诊断为有盲肠炎的病人都确实有盲肠炎。（推理，2%的误诊只会将有盲肠炎的病人误认为没有盲肠炎，从而导致手术量比实际量要低）

若是C)的情况，那么说明随着诊断准确率的提高，没必要的手术量应该会下降。在有机器前，手术量是比实际量要高的。但是看清楚了题目问的是为什么没必要的手术量没有下降，很显然C)不是正确的答案。

其他选项应该不需要一一分析了吧

28. GWD21-Q28:

top executive evidently have faith in the the bank's financial soundness这个很显然不是evidence因为已经是一种主观判断。但是这句话又只是起到承上启下的作用所以还不是main conclusion，得出他是intermediate conclusion之后用来被作者argue并提出真正的conclusion: Thye might well be overoptimistic。

综上得出，选项D是正确答案。
