19. The correct answer is (E). The argument asserts essentially that it was the
marketing campaign, and not some other factor, that was responsible for the high
number of sales of the new version of ActiveWeb compared to competing products. One
way to support the argument is to rule out one or more other factors that might have
been responsible for this phenomenon instead. By implication, choice (E) provides just
this sort of evidence. While favorable third-party reviews of ActiveWeb would serve to
weaken the claim that the marketing campaign was the cause of the sales results,
unfavorable reviews would accomplish just the opposite.
