Complete Question Explanation

Parallel Reasoning. The correct answer choice is (E)

The author concludes that Chen’s plan is better because Ripley’s plan is supported by a self-interested party. This is a Source argument: Ripley’s plan may still be superior to Chen’s, regardless of how selfish her supporters are, or have been in the past. A quick scan through the five answer choices reveals that only answer choice (E) engages in reasoning of the same type. Answer choice (E) is therefore correct.

Answer choice (A): Here, the rationale for opposing a particular plan of action is that this plan is not in the best interest of the city. There is no mention of any alternative plan whose adoption is unadvisable due to the suspect nature of that plan’s supporters. This answer choice is incorrect.

Answer choice (B): For this answer to parallel the argument in the stimulus, it would have to conclude that the school board should not support the plan for a new high school, because the consultants in favor of it were highly paid.

Answer choice (C): The rationale for adopting the mayor’s budget is that it addresses the needs of the city as a whole, unlike the city council’s (which protects special interest groups). If true, this would be legitimate grounds for support of one proposal over another. There is no Source argument flaw in this answer.

Answer choice (D): The rationale for choosing Nomura over Miller is not who Miller’s supporters are (or have done in the past), but rather who Nomura’s supporters are. Since the author is not using the suspect nature of an opponent’s supporters as evidence that Nomura should be elected, this answer choice is incorrect.

Answer choice (E): This is the correct answer choice. See discussion above.

Can you further explain why (E) is correct?

The author's argument is this:

There are two proposals (X and Y). X is better than Y because the prime supporter of Y is someone who is self-interested and basically doesn't care about the town's well being if it conflicts with his needs. [Note: I know the author doesn't address the supporter as an individual, but it makes it easier to understand for me].

For (E) though, there is only one proposal and the author discusses the functionality of that proposal ("it will function well") because its main opponent is the government, who only protects the interest of the city. To me, (E) sounds close to the author's argument structure. What through me off was the one vs. two proposal element I mentioned earlier[/indent]

I chose (C) because it had the two proposals, or options, element and the author was basing 'preferably ' on the fact that the city council only addresses/protects special interests.

Hi Andriana!

In answer choice (E), it's a little more subtle but there are still 2 options/proposals: 1) build the light-rail system or 2) don't build the light-rail system. So it parallels the structure of the stimulus nicely.

This stimulus is another example of a Source Argument. The author tries to attack a proposal based on who supports the proposal, rather than on what the proposal actually does.

In answer choice (C), the argument actually addresses the proposal itself rather than just the supporter of the proposal. It says that the mayor's proposal is preferable because the proposal better addresses the needs of the city as a whole. In the stimulus, we never actually learn which proposal better addresses the needs of the city. Instead, the author makes assumptions about which proposal would be better based on the supporter of one of the proposals.

Hope this helps!

Best,
Kelsey

Hi, the reasoning for why A) is incorrect is there is no mention of an alternate plan, but this is also the case in E. In both cases the alternatives are implementation of the plan or not.

Hi questions,

You are focused a bit on the wrong part of the explanation of answer choice (A). The key aspect of answer choice (A) is missing is the source argument. There's no attacking the source of the proposal because there's no information given about the regional planning commission. In answer choice (E), however, we have a clear source argument. All we know about the opponents of the light rail system is that it's the city government which has a history of ignoring the suburbs. We don't know anything about the city government's REASONS for opposing the light rail system, just like in the stimulus we don't have any information about the reason Smith Stores supports Ripley's plan. We only know facts about Smith Stores, and not about their reasoning.

Hope that helps!
