Several quesions about 2015 GMAT OG, reading comprehension, anone who can answer for me, a thousand thanks!!!


PG 27-------Q2,

The primary purpose of the passage is to
(A) present findings that contradict one explanation
for the effects of a particular advertising
practice
(B) argue that theoretical explanations about the
effects of a particular advertising practice are
of limited value without empirical evidence
(C) discuss how and why particular advertising
practices may affect consumers’ perceptions
(D) contrast the research methods used in two
different studies of a particular advertising
practice
(E) explain why a finding about consumer responses
to a particular advertising practice was unexpeced

Why does not choose answer (A)? The author first presents "economic signaling theory", and then use Kirmani' opinion and his findings to contadict it, why is A wrong?

Kirmani’s third study, as described in the passage,
suggests which of the following conclusions about a
black-and-white advertisement?
(A) It can be repeated more frequently than a
comparable color advertisement could before
consumers begin to suspect low manufacturer
confidence in the quality of the advertised
product.
(B) It will have the greatest impact on consumers’
perceptions of the quality of the advertised
product if it appears during periods when a color
version of the same advertisement is also being
used.
(C) It will attract more attention from readers of the
print publication in which it appears if it is used
only a few times.
(D) It may be perceived by some consumers as
more expensive than a comparable color
advertisement.
(E) It is likely to be perceived by consumers as a
sign of higher manufacturer confidence in the
quality of the advertised product than a
comparable color advertisement would be.

For this qurstion, why is the answer E is wrong? Since E said that " It is likely that....." I think it's relaively consertive, which corepons with GMAC's tone, in addition, it's possible to be percived like that.




Beg for help~~Thanks a lot~~
