119. (28734-!-item-!-188;#058&003375) (GWD 17-Q30)
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.
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.
Ans:B 這題我雖然最後會選B~~不過A選項我有疑問~~想請教大家~~! A選項說 Thank you~這messages對 常客或是偶而來的客人有相同的影響~~我覺得~既然Thank you 都會有相同影響~~那不管是哪一種客人來~~都會付出高於3%的tips~~所以感覺似乎可以當成assumption~!! 但是我把B選項套進A選項後~~感覺如果B選項~~弄成相反的意思 B. Regularly seeing “Thank you” written on their bills would lead restaurant patrons to revert to their earlier tipping habits.代進去A選項後~~就會使A不成立~~因為即使Thank you的作用對兩種客人都相同~~選項中沒說作用是好還是壞~~所以他們都可能反而會因為看到Thank you 而不願意多付錢~~避之唯恐不及~~導致A選項不成立??!! 不知道大家怎麼排除A選項的?? 還是說A選項根本是不相關阿?? 請大家指點迷津一下囉~~謝謝~!!

是不是regular和occassionally这两个概念原arguement并没有提到，属于og里面的irrelevant之类的。我最初也选的A，因为根据OG的推理方式就是，因为几家参观在随意抽取的账单上有谢谢你这几个字，导致客人多付3%的小费。根据这个依据，所以做出了每张账单上都印上谢谢你的字样，这样就会收入增加。
如果这样推理的话，那么唯一推理的过程就是
谢谢你三字-导致客人产生多付的行为-导致收入增加
并没有提到常客和稀客之间的区别，而且这个题目提到的是randomly selected似乎跟常客稀客并没有特指。不知道这样理解对否。因为有可能是稀客的行为，那么A说这个谢谢你对常客和稀客产生同样的作用，有点延伸。
