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.
