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 that 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. 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.

我觉得since topxxxx应该是evidence来支持rumors must be false的，感觉第二个应该是结论，所以选来选去，结果还是选错了：（

你可以这么理解，evidence是不能被反驳的，只有conclusion才行，这题显然也论证了top executives evidently have faith in the bank’s financial soundness这个想法是错的，还是你觉得这句话是对的

main conclusion应该是最后一句since corporate executives have sometimes bought shares...但是文中没有继续对此reasoning

而前面只是简单陈述了一个事实，然后认为“高管表面上对此有信心”，这是第一个小结论；然后增进了一句“可能过于乐观了”，又是一个小结论。
