GWD21-Q28:

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.

这道题怎么看都是B, 答案怎么是啊A?

答案是D

想问第一个BF，since后面不是论据吗（evidence）D的说法是说第一个BF是提出下面质疑的中间结论 这里不太明白（虽然A的第2个BF解释是错误的）

盼NN指点
