In a study conducted in Canada, servers in various restaurants wrote “Thank you" on randomly selected bills before presenting the bills to their customers. lips on these bills were an average of three percentage points higher than tips on bills without the message. Therefore, if servers in Canada regularly wrote “Thank you” on restaurant their average income from tips would be significantly higher than it otherwise would have been.

Which of the following is an assumption on which the argument relies?


A. The “Thank you" messages would have the same impact on regular patrons of a restaurant as they would on occasional patrons of the same restaurant.

B. Regularly seeing “Thank you" written on their bills would not lead restaurant patrons to revert to their earlier tipping habits.

C. The written “Thank you" reminds restaurant patrons that tips constitute a significant part of the income of many food servers.

D. The rate at which people tip food servers in Canada does not vary with how expensive a restaurant is.

E. Virtually all patrons of the Canadian restaurants in the study who were given a bill with “Thank you” written on it left a larger tip than they otherwise would have.

Another way to look at the question is "could the average from tips still increase if this assumption were not true?"
A. Even if the increase came only from occasional patrons, then average of tips would still be higher. This assumption is not needed.
B. Correct. If effect is a function of the rarity of seeing thank you, then regularly writing thank you would not increase average tips. This assumption must be met for the argument to hold.
C. This assumes that knowing that tips are part of the income for servers will lead to higher tips. There is not enough information about this requirement for the argument to hold.
D. Even if initial tipping rates differ, the increase could be shown to be applicable across restaurants and rates, particularly if restaurants of different expense levels were included in the study. There is not enough information to fully evaluate the need for the assumption.
E. The assumption is not needed; as with A, if a small portion of patrons left much larger tips, the average would still be higher.
The correct answer is B.

B-> is the perfect assumption for the conclusion.
-> if servers in Canada regularly wrote “Thank you” on restaurant their average income from tips would be significantly higher than it otherwise would have been.
