any strong reason to eliminate C?
Conclusion: The best way to increase its profits is to release new records very rarely and spend much of its time touring.
Premise: Most popular bands make most of their money on merchandising rather than on record sales.
Unstated Assumption: Touring is somehow connected to merchandise sales and profits more than is releasing new records.
C. Tours are the best ways of exposing fans to new band merchandise.
This answer looks pretty good, but the truth is that we really don't know what drives merchandise sales. Does exposing fans to merchandise result in their buying the merchandise? Whether exposing fans to merchandise results in sales is not clear, and whether the Turtles would tour in order to expose fans to merchandise is not clear. So, arriving at the argument's conclusion does not require assuming that tours are the best ways of exposing fans to new band merchandise, because the argument does not even state that exposing fans to merchandise is the purpose of touring.
So, while choice (C) really seems to be correct, and while I don't think an official question would include an answer choice as close to correct as (C) is, we can eliminate (C).
Now, for contrast, let's consider choice (A).
A. Fans of the band will not discontinue attending concerts and buying band merchandise if the band does not frequently release new material.
Without a doubt, concluding that releasing new records very rarely and spending much of its time touring is the best way for the band to increase its profits requires assuming that fans of the bands will not discontinue attending concerts and buying band merchandise if the band rarely releases new records.
The correct answer is (A).
