ADVERTISEMENT: You cannot buy a more potent pain-reliever than RELIEF without a prescription.
Which of the following statements is inconsistent with the claim made by the advertisement?
(A) RELIEF is not the least expensive non-prescription pain-reliever one can buy. ---->
We only know that no pain-reliever (PR) without prescription is more potent. No info that we can invalidate this statement.(B) Another non-prescription pain-reliever, TOBINE, is just as powerful as RELIEF. ---->
Again, it might be possible since we are not given any information about the competing products. Hence, can be a possibility.(C) Some prescription pain-relievers are not as powerful as RELIEF. ---->
This is also possible, we can think of some less potent version of PR.(D) An experimental pain reliever more powerful than RELIEF is available free-of-charge to subjects who participate in a study. ---->
So this option talks about a PR that is more potent than RELIEF but the scope is related to field of studying the product but not marketing/selling it(E) A non-prescription pain-reliever more powerful than any other, including RELIEF, is available for purchase without a prescription. ---->
Now this is clearly against the information that is stated in the question stem. We are told that RELIEF is at the top of chart when we talk about potency of PR. However, there can be other PR of same potency but we surely can say that no PR that can be obtained without prescription is more potent than RELIEF as it is stated in the argument. Hence this is inconsistent with the information given in the stem.
