That sales can be increased by the presence of sunlight within a store has been shown by the experience of the only Savefast department store with a large skylight. The skylight allows sunlight into half of the store, reducing the need for artificial light. The rest of the store uses only artificial light. Since the store opened two years ago, the departments on the sunlight side have had substantially higher sales than the other departments.
Which of the following, if true, most strengthens the argument?
A) On particularly cloudy days, more artificial light is used to illuminate the part of the store under the skylight.
B) When the store is open at night, the departments in the part of the store under the skylight have sales that are no higher than those of other departments.
C) Many customers purchase items from departments in both parts of the store on a single shopping trip.
D) Besides the skylight, there are several significant architectural differences between the two parts of the store.
E) The departments in the part of the store under the skylight are the departments that generally have the highest sales in other stores in the Savefast chain.

Explanation
The passage compares sales of items in the sunlit part of the store with sales of items
in the artificially lit part of the store and concludes that since the former are greater
than the latter, the presence of sunlight increases sales. The assumption underlying this
argument is that the only significant difference between the two parts of the store is the
presence of sunlight—otherwise, the inherent popularity of goods sold in different
locations, or some other factor, might account for the increased sales. Choice B helps
rule out the possibility that other factors might be involved, by showing that sales are
no greater when the sunlight is taken out of the equation. Therefore it is the correct
answer. Choices D and E both suggest that factors besides sunlight might explain the
discrepancy between sales; therefore they weaken rather than strengthen the
argument, and so are incorrect. Neither Choice A nor Choice C point to differences
between the two areas of the store; therefore they are both incorrect as well.
