(A) The abridgment was prepared by Shakespeare.
(B) The abridgment was created to make Hamlet easier to produce on stage.
(C) The abridgment was produced by an actor who had played a role in Hamlet.
(D) The abridgement was prepared by a spectator of a performance of Hamlet.
(E) The abridgment was produced by an actor who was trying to improve the play.
Remove A, B and D as completely loser choices since they cannot be remotely inferred from the passage. Between C and D, C is "most" strongly inferred from the passage (got the roles of character the actor played right and other parts wrong). Spectator could not reproduce "accurately" one part of speech and "slipshod" other parts. He would have been (logically speaking) slightly more balanced.
Also, I have a question on this
AndrewN if you can help - the answers to "must be true" question types should directly be borne out of the passage. The answer choices provided in this question are not directly influenced by the passage (for eg: there is no reason to say that the actor would not have had a copy of Hamlet). Your thoughts?
