Question Type:
Necessary Assumption
Stimulus Breakdown:
Conclusion: R's performance was as good as B's.
Evidence: Even though B's command of facts was better, we should also consider how reasonable the arguments were, regardless of the underlying facts.
Answer Anticipation:
This feels like a Fill in the Blank assumption. Our author has not said, but is clearly assuming, that ROBERT won the battle of "how reasonable the debaters' arguments were".
Correct Answer:
B
Answer Choice Analysis:
(A) The author needs to assume that Robert was BETTER, not that Britta was BAD.
(B) YES, if R's arguments were equally or less reasonable than B's, then the author would have no reason to conclude that R did just as well as B.
(C) "require" is dangerously strong. The author thinks that "how reasonable your arguments were" is relevant to evaluating your debate performance, but the whole argument is in RELATIVE terms. The author isn't assuming anything about the ABSOLUTE ideas of "a GOOD performance" or "a VERY REASONABLE argument".
(D) There's no reason the author needs to assume that B wasn't in full command of the facts. If she WERE in full command of the facts, it wouldn't change the argument at all.
(E) "requires" is dangerously strong. Again, the author is scoring the debate in RELATIVE terms, who had BETTER command of the facts and whose arguments were MORE reasonable. The author doesn't need to assume that winning requires a good command. He might believe that better command of facts + more reasonable arguments is enough to win a debate, as long as your opponent had worse command of facts + less reasonable arguments.
Takeaway/Pattern: This seems like an easier question, for where it is in the section. A lot of Necessary Assumption questions are just testing this, "go ahead and SPELL OUT THE IMPLIED IDEA".
If I argued, "Dave said we should go to Taco Town, because it's closer. But we should also consider which restaurant is cheaper. Hence, we should go to Fajitaville."
What am I assuming?
Fajitaville is cheaper.
