1 LSAT question

primefang

Most parents who are generous are good parents,but some self-centered parents are also good parents. Yet all good parents share one characteristic: they are good listners

Which of the following is true

B> some parents who are good listeners are not good parents
C> most parents who are good listeners are generous
D> some parents who are good listeners are self-centered

What is the answer, let's disscuss

primefang

most generous parents  ----- > Good parents----------> Good listeners
Some self-centered parents--------> good parents------> Good listeners

因为 此处的most 和 some 是相对于这两个特定人群的比例，
但是当他们组成一个合集的时候，由于不知道其具体人数，所以无法确定到底是 generous parents or self-centered parents 占多数，所以只能选有some 的答案

tongxun

是的，因为用了most所以不对。因为你并不知道两类人的具体比例。若换成SOME就对。

doris

C为什么不对啊？是不是因为用的是MOST啊/？如果换成是SOME 的话那对不对呢？

doris

答案好象是D，但是为什么啊？我当时也想了很久，觉得自己想的很牵强，请指点

tongxun

D。肯定是。
