answer?

@Lucas, Good job—(E) is the correct answer! (E) says, "be thinner in the portion of the glass that is under the pressure of the object than in those portions of the glass that are not under that pressure" (E) most logically completes the argument because we know from the stimulus that the glass will flow away from the object, so (E) is the correct answer choice. Does this answer your question? Let us know if you have any other questions!

I take it that "glass is fluid" is a counter-intuitive claim designed to fool us and waste our time, and that we ought to simply assume that it is true regardless of our apprehension of doing so.

I agree that this is something we should take as true, but not because it is trying to fool us. but because its a premise.
