One randomly selected group saw a speaker lecture on environmental ethics to a large, attentive audience, and a different randomly selected group saw the same speaker give the same lecture, with identical mannerisms, but to a smaller, less attentive audience. The first group called the speaker thoughtful and assured. The second group called the speaker vague and long-winded.
The information above can best serve as part of an argument against which of the following claims
A．The same social behavior can appear quite differently to different people when it is viewed in different social contexts.
B．If the second group had seen the speaker lecture to a more attentive audience, its judgment of the speaker’s personal qualities might well have been different.
C．People’s judgments of a speaker’s personal qualities are based primarily on what the speaker says and the mannerisms with which the speaker says it.
D．A listener’s convictions about a speaker’s claims can be influenced by other people’s reactions to those claims.
E．(E) A randomly selected group can sometimes arrive at a consensus about the personal qualifications of a speaker in a particular social situation.
