Critical Reasoning

Sales of a new chocolate bar were considerably boosted recently by an advertisement that featured a classic rock song. The candy manufacturer's decision to also use classic rock songs in commercials for its older and more popular products, in the hopes of boosting profits, is NOT based on the assumption that ___________________.

A. thanks to the new advertising strategy, all of the company's older products will sell at least as well as the new chocolate bar.
B. sales of a particular product can be increased by a memorable or catchy advertisement campaign.
C. use of classic rock songs will be more commercially effective than the advertising techniques currently used by the company for its older products
D. the majority of customers who buy one kind of candy bar from the company will not stop buying other candy bars made by the same company.
E. the licensing costs associated with using classic rock songs in commercials will be substantially offset by the increased profits resulting from those commercials.

D?

An assumption is a claim that MUST BE TRUE in order for the conclusion to be true, given the other claims. The conclusion of the manufacturer is that they will boost profits by using classic rock songs in commercials for older, more popular products.

A. thanks to the new advertising strategy, all of the company's older products will sell at least as well as the new chocolate bar.

In the stem, it is stated that the older products are more popular. If the these sell at least as well as the new chocolate bar, it is possible for sales to drop. Therefore a boost in profits does not necessarily follow, and this is not an assumption relied on by the manufacturer's decision.

Is the question about finding "all assumptions supporting EXCEPT one."

Confused

D cannot be an assumption. OA?

All assumptions will lead to one conclusion - gain in money...

Only A has a okay okay go for money...

+1 for A

Well... my initial answer was D.

But I think if we apply negation method, A sounds ok. If A is not true, assumption fails...If the company does not assume to boost sales of candy, why do they try the same strategy for an other product?

Definetly A

+1 to A
