自去年12月開始，Kory每週五下午固定舉辦了[。玩G妹 ONE GMAT ] K書團/助教時間，
邀請正在準備GMAT的同學。就算沒有問題想問，也可以一起聚在教室唸書，
至今已經有超過100人次參加囉～
而每次K書團後，Kory都會總結當天同學最容易卡關的問題，
現在就一起重新分享在GMAT版，回饋眾版友：
SC的部分
1. rate for的意思是某東西的價錢，rate of是指頻率或者速率之類的，兩者意思完全不一樣喔！
2. Unlike most severance packages, which require workers to stay until [ the last day scheduled to collect, workers at the automobile company are eligible for its severance package] even if they find a new job before they are terminated.
(A) the last day scheduled to collect, workers at the automobile company are eligible for its severance package
Unlike中的Package不能跟主要子句的主詞workers比
(B) the last day they are scheduled to collect, workers are eligible for the automobile company's severance package
Unlike中的Package不能跟主要子句的主詞workers比
(C) their last scheduled day to collect, the automobile company offers its severance package to workers
Unlike中的Package不能跟主要子句的主詞the automobile company比
(D) their last scheduled day in order to collect, the automobile company's severance package is available to workers
這題語意是不像一般的severance package，接著用, which修飾甚麼樣的severance package，就是會要求員工待到他們被安排的最後一天才能collect(也就是最後一天之後才能拿到)，那個to stay是跟著require，而in order to是跟著stay的，而collect的受詞是前面的package，正確答案
(E) the last day that they are scheduled to collect, the automobile company's severance package is available to workers
語意變得非常奇怪，變成了他們被要求要待到最後一天，甚麼樣的最後一天？用限定用法修飾那一天，特別注意that在形容詞子句裡當受詞用，are scheduled to collect的collect是跟著scheduled，而collect的受詞會變成在collect這個天，語意完全不通
The use of lie detectors is based on the assumption that lying produces emotional reactions in an individual [that, in turn, create unconscious physiological responses.]
(A) that, in turn, create unconscious physiological responses
注意，that不能拿來修飾individual，如果是要修飾individual，那要用C的Ving或者E的who，然而這邊的語意到底是甚麼呢？應該是說謊會在人身上產生情緒的反應，而這個反應"in turn"會產生無意識的physiological response才對，所以這個that是要跳過前面的介係詞片語修飾前的面的responses，特別注意that後面的動詞用的是create，正確答案
(B) that creates unconscious physiological responses in turn
明顯想用that修飾單數的individual，慢走不送
(C) creating, in turn, unconscious physiological responses
in turn的位置略有不同，但更重要的判題點在於如果是變成修飾individual，語意就會變成謊會在某種人身上產生情緒的反應，哪種人？就是那種in turn會產生無意識的physiological response的人，語意不通
(D) to create, in turn, physiological responses that are unconscious
to會變成跟著produce，也就是語意會變成說謊會為了要in turn產生無意識的physiological response而在人身上產生情緒的反應，更不通
(E) who creates unconscious physiological responses in turn
同(C)
CR的部分
OG124. It is widely assumed that people need to engage in intellectual activities such as solving crossword puzzles or mathematics problems in order to maintain mental sharpness as they age. In fact, however, simply talking to other people—that is, participating in social interaction, which engages many mental and perceptual skills—suffices. Evidence to this effect comes from a study showing that the more social contact people report, the better their mental skills.
Which of the following, if true, most seriously weakens the force of the evidence cited?
這題私以為是OG數一數二難的題目，是一題複合概念型的反駁題
先把題目大概看懂：大部分人assume(預告轉折)人們必須要從事智力相關的活動，比方說玩拼字遊戲或者解數學題，才能在年華老去的過程中維持住智力。但事實上，參與社交活動就需要很多智力與感知上的應用，所以就足夠了。證據是根據研究顯示，研究對象回報參與越多的社交活動，他們的智力就越好。
結論句大概會像這樣：
Social interactions ↑ ----------> 智力↑ (已發生)
這題我個人的第一直覺就是倒因為果，也就是也可能是因為智力較高，所以這些人可以參與比較多的社交活動。相信同學可能會質疑為什麼我可以馬上想到這是倒因為果，原因是當我想到結論句是這樣的時候，我發現這兩件是無法確認誰先發生，所以當然這題可以是他因生此果，但我會先試著考慮倒因為果，試試看之後發現果然有可能可以解釋，就把這個思路放心上。
(A) As people grow older, they are often advised to keep exercising their physical and mental capacities in order to maintain or improve them.
這些人被建議去做這些事沒辦法當成他因，而且完全沒有提到social interactions
(B) Many medical conditions and treatments that adversely affect a person’s mental sharpness also tend to increase that person’s social
isolation.
第一時間沒看出來，但至少mental sharpness跟social都有提到。先保留。
(C) Many people are proficient both in social interactions and in solving mathematical problems.
同時兩件事都能做到無法提供他因
(D) The study did not itself collect data but analyzed data bearing on the issue from prior studies.
完全沒提到其他studies，而且就算真的是這樣，那也不代表這個結論是錯的
(E) The tasks evaluating mental sharpness for which data were compiled by the study were more akin to mathematics problems than to
conversation.
task的內容無關
於是回頭把B選項搞清楚，這是一個用無因無果(或者說是反因反果)來支持倒因為果的反駁，更精確地說，你會發現這題是一個correlation的概念，Social interactions ↑ ----------> 智力↑的倒因為果就是智力↑ --------> Social interactions ↑，也就是這兩個因子是所謂有起點(智力)的正相關，然後B選項的意思就是當智力↓的時候，Social interactions也會↓，這就支持了剛剛上面的線性關係，也就是支持了倒因為果的反駁！
這題巧妙的應用了幾個CR的重要觀念，包括倒因為果反駁，correlation，以及無因無果來強化因果，的確是相當漂亮的題目！
