89. 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 fi nancial collapse, have been greatly relieved. They reason that, since top executives evidently have faith in the bank’s fi nancial soundness, those worrisome rumors must be false. Such reasoning might well be overoptimistic, however,since corporate executives have been known to buy 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 fi rst describes evidence that has been taken as supporting a conclusion; the second gives a reason for questioning that support. (B) The fi rst describes evidence that has been taken as supporting a conclusion; the second states a contrary conclusion that is the main conclusion of the argument. (C) The fi rst provides evidence in support of the main conclusion of the argument; the second states that conclusion. (D) The fi rst describes the circumstance that the argument as a whole seeks to explain; the second gives the explanation that the argument seeks to establish. (E) The fi rst describes the circumstance that the argument as a whole seeks to explain; the second provides evidence in support of the explanation that the argument seeks to establish. ===================================================== 我认为这题有俩结论： 1.bank’s depositors: those worrisome rumors must be false 2.author:Such reasoning might well be overoptimistic, however(main conclusion) 答案A：第一个BF支持“一个”结论（注意是一个结论，显然支持第一个结论，但不是主要结论）第二个BF是作者的结论，即主要结论，用来反对第一个结论的 此题的逻辑思路：一个背景证据 推出结论1 接一个结论1的理由，作者提出结论2来反对结论1，并提出了自己的理由
