Complete Question Explanation
Strengthen—PR, SN. The correct answer choice is (D)
Interestingly, this is the second Strengthen—Principle question in a row. What distinguishes this question from Question 7 is that the principle is explicitly provided in the stimulus. This focuses your approach on the elements of the principle in the abstract. The most efficient approach here is to identify the elements of the principle, compare those elements to the facts in the “Application” portion of the stimulus, and identify an additional fact that would make the principle and the application scenario fit together better.
The principle is a conditional rule, that can be diagrammed as:
BFD = burden of a proposed policy change would fall disproportionately on people with low incomes
PC = policy change should not be made
Comparing the abstract principle to the facts given in the Application, we see that the necessary condition is met. The author concludes the city should not change its policy to permit the reintroduction of rock salt as a de-icing agent. What is missing from the Application is any indication that this change in policy would disproportionately burden people with low incomes.
Do not waste time trying to prephrase precisely how the policy change would burden people with low incomes disproportionately. There are conceivably many ways in which LSAC could establish this burden. Instead, move to the answer choices on the lookout for the one choice that explains how those with low incomes would be burdened disproportionately, especially one that links to the only potential negative impact discussed by the stimulus: corrosion damage to automobiles.
Answer choice (A): This answer choice weakens the application of the principle because it states that lower-income people are less likely to drive cars. If so, they would not be burdened disproportionately by the risk of rock salt corroding their cars.
Answer choice (B): This choice has no effect on the conclusion because there is no evidence in the stimulus that re-introducing rock salt as a de-icer will increase the cost of road maintenance. It is just as likely from the information given that using rock salt is a less expensive option that could reduce maintenance costs.
Answer choice (C): This choice has no effect on the application because nothing in the city’s plan requires the town residents, low-income or otherwise, to purchase new cars.
Answer choice (D): This is the correct answer choice. This choice supports the application of the principle, because if lower-income people are more likely to buy older cars, which are not as well protected from salt’s corrosive properties, then they are more likely to have a car that would be corroded by rock salt on the roads.
Answer choice (E): This choice weakens the application, because it implies that drivers with lower incomes are less likely to come into contact with rock salt, and therefore will be less likely to suffer from corrosion-related issues.
