Question Type:
Flaw
Stimulus Breakdown:
Conclusion: We should vote to approve the act.
Evidence: My colleague said the act would deter investment, but she's voted to deter investment in the past, so this can't be her real reason. Since she hasn't given a real reason, the real reason must not be very persuasive.
Answer Anticipation:
Jeez … what a trainwreck. There are like three big problems, all of which could be an answer:
Unproven vs. Untrue (even if we establish that we have no good reason AGAINST voting for this act, the author has provided no good reason to vote FOR this act)
Attacking the Person (You may have committed a behavior in the past that you are now sincerely warning people against doing ... you can't disqualify someone's opinion by saying they haven't always behaved in accordance with that opinion)
Term Shift (near Circular) going from "if it hasn't been revealed, it must not be persuasive".
Correct Answer:
B
Answer Choice Analysis:
(A) There's no personal character trait mentioned, so we can stop reading five words in.
(B) Yes! The reason Attacking the Person is a flaw is because we should address the IDEAS not the source of the ideas.
(C) The author doesn't need to assume that the colleague is in the minority. Even if the colleague is in the majority, the author could still make his crappy argument. Perhaps if this answer read "presumes that the majority opinion in the legislature is not that this act would deter investment", then I would be okay with it.
(D) The author is saying nothing about voters, so no assumptions need be made.
(E) The author doesn't directly acknowlege this specific reason for the colleague's opposition, but since the author thinks the colleague's STATED opposition is not her REAL reason, then the author would not be surprised nor damaged to learn about (E).
Takeaway/Pattern: Instead of taking the colleague's argument head on, (arguing that the act does NOT deter investment, or arguing that EVEN THOUGH it deters investment, its advantages outweigh that disadvantage), the author tried to disqualify that concern by pointing to the colleague's past voting record.
