[問題]GWD0-40(同天山 9-Q40)

[Behemoth]

Q40:
For most people, the left half of the brain controls linguistic capabilities, but some people have their language centers in the right half. When a language center of the brain is damaged, for example by a stroke, linguistic capabilities are impaired in some way. Therefore, people who have suffered a serious stroke on the left side of the brain without suffering any such impairment must have their language centers in the right half.

Which of the following is an assumption on which the reasoning in the argument above depends?

A. No part of a person’s brain that is damaged by a stroke ever recovers.
B. Impairment of linguistic capabilities does not occur in people who have not suffered any damage to any language center of the brain.
C. Strokes tend to impair linguistic capabilities more severely than does any other cause of damage to language centers in the brain.
D. If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages at least one of them.
E. It is impossible to determine which side of the brain contains a person’s language centers if the person has not suffered damage to either side of the brain.

答案是d,可以接受
但a怎麼解決呢?

B爺

我覺得題目問 people who have suffered a serious stroke on the left side of the brain
而不是問 "已經recover"的病人

就算會recover, 但是現在在suffer的人(((還沒recover吧))))??

the two groups are different........
況且題目也沒提到recover (out of scope你為啥要選<---江樸)

我的想法

米克踢小姐

真是不好意思, 邏輯上黃冠文的,所以基礎可能比較薄弱一點...:P

您的意思是本文根本沒講recover, 那就爽快的把他槓掉是吧

讚喔 其實我也是這樣想, 但是沒啥信心 所以特來求證一番 多謝賜教~~~

[魚]

為啥我絕得答案是 B (H)

[agk99]

d，沒問題的
micht說的有道理

[訪客]

D好像不確定說到底impair哪邊,不知右邊還是左邊,但結論給的是壞的左邊,但是掌管語言的部分是在右邊,所以沒影響,
還是我對結論有誤會,可以自己推導,壞右邊,掌管語言在左邊
我選的C

[QQcandy]

嗯 金剛妹說的有理... 同意 a 不是正確答案...

但是正確答案 d, 我有點不懂他的意思耶 ! 尤其是 那段 any serious stroke affecting that side of the brain damages at least one of them.

[QQcandy]

ㄛㄛㄛ

突然被雷打到 有點頓誤 他是要規定前提一定要中風就是會damage兩邊的其中任一邊才會得出結論

我覺得 c 根中風言不嚴重無關吶

[訪客]

B:太general, 沒有涵蓋到題幹的結論所提到的概念

[liwuu]

我投B一票...
B說明只有damage center of brain才會出現impairment of linguistic capabilities
所以才可以推論說要是傷到左邊卻沒有出現impair時,center of brain必在右邊!!

[shopcat]

我也是選B
我可以理解為何選D 因為是要找前提
所以D說左腦要有被stroke到語言區 然後回到題幹才可以判定語言區在右腦
可是我不能理解為何B錯
因為B的意思不是也說要語言區有被stroke嗎
請教一下囉

[agk99]

對不起
我變心了，現在和魚說對不起
我改選B

D真不像assumption的答案

[Calvin]

答案是D沒錯

D取非後，原文結論就推翻了

[reohuang]

答案是D沒錯

D取非後，原文結論就推翻了

我個人也覺得D對喔~

B. Impairment of linguistic capabilities does not occur in people who have not suffered any damage to any language center of the brain.
D. If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages at least one of them.

文章推論:Therefore, people who have suffered a serious stroke on the left side of the brain without suffering any such impairment must have their language centers in the right half.

D假設:如果stroke在left side，那他一定會影響到language center(damages at least one of them)
如果沒有D這個assumption就有可能發生:
stroke on the left side & 沒有影響到left side的language center
文章推論會不正確

B假設:要language center受傷的人才會影響到linguistic capabilities
可是有可能有其他原因影響到linguistic capabilities 才對
例如昨天拔智齒臉腫的跟麵龜一樣，結果一個禮拜不能講話
有其他原因也可能也影響到了linguistic capabilities
爛例子不過大概這個意思~

請繼續討論

答案是D沒錯

D取非後，原文結論就推翻了

請教Calvin，常常看到有人運用"取非法"作題，似乎看起來很好用，可我真是一點概念也沒有，可不可以傳授一下如何運用取非解邏輯題
