GWD 21-28

Since it has become known that several of a bank’s top executives have been buying shares in their own bank, the bank’s depositors, who had been worried by rumors that the bank faced impending financial collapse, have been greatly relieved. They reason that since top executives evidently have faith in the bank’s financial soundness, those worrisome rumors must be false. They might well be overoptimistic, however since corporate executives have sometimes bought shares in their own company in a calculated attempt to dispel negative rumors about the company’s health.

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

A.     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.

B.     The first summarizes the evidence used in the reasoning called into question by the argument; the second is an intermediate conclusion supported by the evidence.

C.     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.

D.     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.  (E)

E.      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.

这题答案是e，我选d，请问e怎么解释，是不是答案错了。

有谁能解释一下D 吗？我怎么觉得一个都不对？当然如果勉强要选的话，我会选D,至少第二个Bold face是main conclusion，可第一个怎么是intermediate conclusion 呢？我怎么看怎么觉得应该是evidence 之类的。

有谁能帮帮我吗？还有一个星期就考了，我竟然还这样？！

我也选的D，原来都是用关键字的方法基本不读原文做的，但是现在读了原文觉得 those worrisome rumors must be false才是main conclusion～～

请教NN对不对呢？

如果第一个是中间结论，那么前提是什么呢？
