Official Solution:
Two well-known neighborhood restaurants, Cancan Club and Chez Shay, provide valet parking exclusively for their patrons. At Cancan Club, the service is complimentary and abundant public parking is available close by. Chez Shay’s valet service, by contrast, is optional but costs $10 per vehicle, and virtually no other parking can be found within a three-block radius. The two restaurants are similar in size and attract comparable numbers of diners, and each reserves its valet lot solely for guests. Nevertheless, the valet area at Chez Shay consistently handles more cars than the one at Cancan Club.
Which of the following can most reasonably be inferred from the information above?
A. Patrons of Chez Shay are, on average, wealthier than patrons of Cancan Club.
B. Many diners who use valet parking at Chez Shay also valet their cars when they eat at Cancan Club.
C. Diners at Chez Shay are willing to pay the valet fee rather than search for scarce street parking nearby.
D. Customers choose Chez Shay primarily because they prefer its food to that of Cancan Club.
E. Even if additional free parking became available near Chez Shay, its diners would still choose the valet option.
Inference required: Chez Shay’s valet lot is busier even though it charges $10 and has no nearby public parking. The safest conclusion is that diners there willingly pay the fee rather than hunt for scarce spaces.
A. Patrons of Chez Shay are, on average, wealthier than patrons of Cancan Club. [Incorrect] — The information says nothing about diners’ incomes; higher valet usage alone does not prove greater wealth.
B. Many diners who use valet parking at Chez Shay also valet their cars when they eat at Cancan Club. [Incorrect] — No data indicate overlap between the two restaurants’ customer bases or parking habits.
C. Diners at Chez Shay are willing to pay the valet fee rather than search for scarce street parking nearby. [Correct] — With virtually no other parking within three blocks, the busy paid valet lot shows diners accept the fee instead of looking for nonexistent alternatives.
D. Customers choose Chez Shay primarily because they prefer its food to that of Cancan Club. [Incorrect] — The passage does not compare food quality or diners’ reasons for choosing one restaurant over the other.
E. Even if additional free parking became available near Chez Shay, its diners would still choose the valet option. [Incorrect] — This projects future behavior not supported by the given facts; the current situation involves a lack of free parking.
Key takeaway: Choice C stays within the presented facts, linking the scarcity of nearby parking to diners’ willingness to pay the valet fee.
