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.

An assumption if proven wrong, will negate the conclusion.
Conclusion here is: Thank you letters increases -> tip increases.
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
- even if it does not have same impact on the regular and occasional patrons, it doesn't matter. It is not mentioned who will be impacted much or who will not be impacted at all.
B. Regularly seeing “Thank you” written on their bills would not lead restaurant patrons to revert to their earlier tipping habits
negating: Regularly seeing “Thank you” written on their bills would lead restaurant patrons to revert to their earlier tipping habits. Hence, tip will not increase.
C. The written “Thank you” reminds restaurant patrons that tips constitute a significant part of the income of many food servers
- does not remind - no conclusion whether tip needs reminders or not.
D. The rate at which people tip food servers in Pennsylvania does not vary with how expensive a restaurant is
?? Out of context.
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.
- I had earlier chosen this. But later I realized it is almost what is mentioned in the passage, and hence not unstated assumption.

This is my first answer explanation. Not sure how convincing I might sound, but would appreciate if you will hit kudos to keep me motivated.
Should there be any flaw, please let me know.
