   We only have information about sweetness, so we can't derive anything about who take pleasure in the sweetness and how much.

   Why this is right

   This is close to what we were anticipating. Since this new substance has hit the mathematical limit (the fewer the molecules required to activate a receptor, the sweeter it's perceived to be), and you can't be fewer than 1 molecule, or else you're not even present, this would be the maximum perceived sweetness.

   The more molecules of a substance that are required to activate a single sweetness receptor, the more bitter that substance

   This answer would be fine if it said "the more molecules it takes, the less sweet it's perceived to be" (although you won't really ever see an answer just flipping one individual fact and regurgitating it). This is playing off a leap, that the logical opposite of sweet is bitter, or that "less sweet" = "more bitter". Bitter and sweet are not logical opposites. I don't even know if sour and sweet are logical opposites. I think the tongue just has different taste capacities: sweet, salty, bitter, sour, umami (maybe that's it?)
