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

>> "If-then" question: If "regular" thank you => "regular" tips = this is what happened "after" regular thank you. This implies "before" regular thank you, the tipping was irregular.

Hence, we have to find a answer choice that would mean: "regular" thank you =/ "regular" tips. This can be the case if patrons do not care about the new thank you and continue their "before thank you" tipping habits.

Thus, clear winner is B

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 Pennsylvania does not vary with how expensive a restaurant is
E. Virtually all patrons of the Pennsylvania restaurants in the study who were given a bill with “Thank you” written on it left a larger tip than they otherwise would have.

B is correct.

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 --> great, but that doesn't help us

B. Regularly seeing “Thank you” written on their bills would not lead restaurant patrons to revert to their earlier tipping habits --> CORRECT; this helps ensure tips will remain higher than before

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

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

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

Negation of four CHOICES -- A, C, D, and E -- does not cause the conclusion to fall apart.

Even if the rate at which people tip varies with the level of restaurant, the study showed that tips were 3% higher - percent is a relative value, regardless of the base. So whether they used to tip 10% or 15% before the "Thank You" experiment, they still tip 3% higher, on average, after.

The conclusion specifically ties the act of seeing "Thank You" on the bill to tipping more. Only choice B causes this link to break down - seeing "Thank You" would no longer cause customers to tip more.

Initially went with E,

i have one doubt regarding Option B

B says "earlier habits" an earlier habit can a patron giving less tip or more tip if the tip is less then the servers are earning more and if the tip is more then the servers earn more........

so can anyone justify the above reasoning

Here, "earlier tipping habits" = 3 percentage points lower than after seeing the handwritten notes. Hope this makes sense!
