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.

Answer: B
不懂~~~>"<~B是什麼意思?
我選D耶~~
假設前提要是小費%不變~~萬一如果小費收的%高到一個程度~~不要說寫THANK YOU了~就算在紙上寫說我比貝克漢還帥~我死都不會再提高給小費了~因為原本的就太高了啊!

題目說 在P這個地方的不同餐廳做試驗 ,有寫"Thank you"的bill 會收到比較多的小費

問假設
B) 客戶不會因為一天到晚看到"Thank you" 就習以為常 之後就假裝沒看到 恢復到以前給小費的習慣 (給比較少)

請問e要怎麼刪除?
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.

感覺也很像是假釋 阿..

e選項取非不反駁結論
所以無效

維尼大，

抱歉我不是很了解你說的。如果我將(E)的答案取非，就變成
"幾乎所有餐廳的顧客看到帳單上有Thank you，給的小費並不會
比他們原本給的還要多"
這樣的話不就反駁了題目最後一句所說
"會寫Thank you在帳單上的服務生所得到的小費比較多"

是我的思路哪裡出了問題嗎?

你取非的句意跟我的不太一樣
e選項加上not
在英文上我覺得比較像是 not virtual all
而不是像你說的 大家都不留比較多的小費 :)

阿 我終於懂了，

謝謝維尼大的幫忙

小弟我認為E基本上是一個無關選項
因為關鍵字"in the study", 現在題目在討論的是未來如果這麼做是否會收到額外的小費, 時間點基本上已經不是在study的時候了,所以時間焦點轉移,是無關之選項!

Open to discuss~

想請問一下, A哪裡錯了呢?

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.

"Thank you" messages 效果對於常客跟偶爾去的客人一樣
可是題目沒有提到這兩種客人比例，所以假定店裡幾乎都做熟客生意，如果thank you 效果不同(A取非)，偶爾去的客人小費給的少但比例很少，對於結論起不了weaken作用，店收入還是會上升(因為比例少的沒有影響力)

但選項就是說 效果一樣呀~
( the same impact on... )

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.

Thanks.
