Researchers studying artificial sweeteners have long claimed that the perception of sweetness is determined by the activation of a single type of receptor on the tongue, called a sweetness receptor. They have also claimed that any given individual molecule of substance can activate at most one sweetness receptor and that the fewer molecules that are required to activate a receptor, the sweeter that substance will be perceived to be. Now the researchers claim to have discovered a substance of which only one molecule is needed to activate any sweetness receptor.
Which one of the following conclusions is most strongly supported by the researchers’ claims, if all of those claims are true?
(A) The more sweetness receptors a person has on his or her tongue, the more likely it is that that person will find sweet sensations pleasurable.
(B) In sufficient quantity, the molecules of any substance can activate a sweetness receptor.
(C) No substance will be found that is perceived to be sweeter than the substance the researchers have discovered.
(D) A substance that does not activate a sweetness receptor will activate a taste receptor of another type.
(E) The more molecules of a substance that are required to activate a single sweetness receptor, the more bitter that substance will be perceived to be.

Using POE:
A) Not mentioned anyhwere.
B) Not Mentioned .
C) Can be inferred since the sentence says that one molecule can at most activate one receptor and researchers claim to have found that one molecule. Lets wait and see more options though.
D) Not mentioned
E) Bitter word is not mentioned anywhere in the paragraph.
SO using POE the closest and the only answer appears C)

From Manhattan Prep:
We know the following:
1. The fewer molecules that are required to activate a receptor, the sweeter that substance will be perceived to be.
2. The researches claim to have discovered a substance of which only one molecule is needed to activate any sweetness receptor.
If all the researchers' claims are true, then there is nothing that has fewer molecules required to activate a receptor. One is the minimum, while still having some. If nothing has fewer molecules required to activate a receptor and the fewer molecules required the sweeter the substance is, then nothing can be found that is sweeter than this particular substance. Best expressed in answer choice (C).
It's kind of like the following crude analogy. If the taller you are the better at basketball you are, and Steve is the tallest basketball player ever, then Steve must be the best basketball player ever.
(A) is out of scope. Pleasurable is unsupported.
(B) is unsupported. We don't know that any substance can activate a sweetness receptor.
(D) is not necessarily true. Other types of receptors are simply not discussed.
(E) would make sense since the fewer the receptors required, the sweeter the substance is. But it doesn't have to be true that the more receptors required, the more bitter something is. Bitterness is unsupported by the stimulus.
