The sandwich shop owner concludes that making his prices more competitive with the health food restaurant’s prices is the best way to counteract his declining sales. Since the validity of this conclusion depends on the assumption that pricing is the root cause of the declining sales, an assumption that explicitly defines the relationship between price and sales, or an assumption that eliminates an alternate cause for the declining sales, will help justify the owner’s logic.
(A) CORRECT. This assumption eliminates the possibility that the sandwich shop is losing business because people actually prefer the food at the health food restaurant to the food at the sandwich shop. This gives more credibility to the argument that the decline in sales is a result of pricing.
(B) Sales records from six months ago fail to provide any significant information about the relationship between price and the current decline in sales.
(C) While this could possibly provide evidence that the sandwich shop’s prices are higher than normal, it doesn’t prove a connection between price and the recent decline in sales. Also, the neighboring town could have its own set of market factors that are completely different from the factors affecting sales in the owner’s market.
(D) Rather than eliminating an alternate cause for the decline in sales, this could possibly offer an alternate cause. If the sandwich shop does not offer healthful food items, consumers may be opting for the healthier restaurant next door. This would certainly weaken the owner’s conclusion, not justify it.
(E) This information fails to establish a relationship between the owner’s pricing and the decline in sales.
