Complete Question Explanation
Flaw in the Reasoning, CE. The correct answer choice is D.
The stimulus makes a classic correlation-causation error, and it pays to spot it before you dive in on the answer choices. The premises establish, via two comparative claims, a correlation between two things: (1) Joshi's reelection campaign's financial support from property developers (which is stated to be higher than any other city councilor); and (2) Joshi's voting record in favor of property developers (which is stated to be more favorable than any other city councilor). From this correlation, an erroneous conclusion is drawn that one of these things must be causing the other, in other words the conclusion says that the financial support from the developers (their campaign contributions) must be influencing (a clear causal indicator term) Joshi's city council votes (his voting record favoring the property developers).
In many mistaken correlation-causation arguments, there is a possibility that the cause and effect relationship runs in the opposite direction from what the author has concluded. That is true here as well. It is entirely possible that Joshi (for independent reasons like his ideology or his past) often votes in favor of property developers. And since property developers notice this and like it, that leads them to give him campaign contributions. Such "reversed causation" doesn't have to be true. But it is a possibility that the argument hasn't ruled out, thus it undermines the conclusion, which was stated with certainty. We need to look for an answer choice describing an error in causal reasoning (our prephrase).
Answer Choice (A): The argument doesn't refer to the events in question occurring sequentially, so this cannot be the correct answer. In other words, we cannot tell from the premises whether the contributions to Joshi's campaign preceded Joshi's votes favoring property developers.
Answer Choice (B): This answer choice describes an error of conditional reasoning. There is no conditional relationship explicitly stated in the premises, making this answer very unlikely to be correct. Furthermore, the argument's structure clearly shows (because there are two premises) that the author is not treating just one thing by itself as "sufficient" to prove the conclusion.
Answer Choice (C): The conclusion does not make a "moral judgment." The question of influence is one of fact (was there causation or not?) and does not imply moral judgment (i.e. a "right" or a "wrong"). We're very likely to read the conclusion as a moral condemnation, but that's only because of our outside assumptions. When a claim merely refers to influence without more, one cannot tell whether the person making that claim thinks the fact of influence is right or wrong.
Answer Choice (D): This is the correct answer choice. This answer choice fits our prephrase. The argument presumes that one thing (campaign contributions) caused another (Joshi's voting record) when there is a possibility (since nothing in the argument rules it out) that the campaign contributions could be an effect of Joshi's voting record.
Answer Choice (E): Answer choice E describes a "circular reasoning" flaw. Because none of the premises restate the conclusion's claim about "influence," this cannot be the correct answer.
