This stimulus is partly conditional and partly causal, pradhyumanbhutani, so that may be the source of some of your confusion. The first sentence is conditional as indicated by the use of "unless," and it could be diagrammed this way:
CC (complete the complex)
RB (road is built)
The next part is causal: completing the complex will strengthen the economy, which will in turn benefit the residents. We COULD diagram those conditionally, making the causes sufficient for the effects, but we don't have to do that.
Finally, the conclusion is neither conditional nor causal. The author thinks residents should vote for a tax that would pay for the road. Why? Because although the road may not guarantee that the complex will be completed, it would at least allow it to be completed, and completing the complex carries with it those benefits.
Our job is to strengthen the claim that they should vote for the tax, and our prephrase should be something like "people should do things that could help them get benefits." We could be a little more specific than that if we wish: "if building a road might benefit people, then those people should vote for a tax to build the road."
Basically, look for an answer that suggests that there is a good reason to vote for the tax! Strengthen the claim that the residents
should vote for it.
Answer A doesn't help because we don't know if this construction project is necessary. We know it would help, but not that it is required. This answer therefore doesn't apply to the facts in the argument.
Answer B looks like a Mistaken Reversal of what we want. Diagram it and you'll get: Should Vote for Tax
Benefit; we want it the other way around.
Answer C doesn't tell us whether anyone should vote for this tax. It just indicates that a tax is preferable to a debt. But maybe they shouldn't support finding the project at all? We need something that more affirmatively gets people to vote for the tax.
Answer D is irrelevant, because the issue in the argument isn't who
pays the tax, but rather about who should vote in favor of the tax. This answer doesn't give anyone a reason to vote for the tax.
Answer E is correct because it matches our prephrase nicely: if you will benefit (and we know everyone will, according to the stimulus), then you should vote in favor. That helps the argument a lot, and must be our winner.
