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 listeners.
If all of the statements in the passage are true, which one of the following must also be true?
(A) All parents who are good listeners are good parents.
(B) Some parents who are good listeners are not good parent.
(C) Most parents who are good listeners are generous.
(D) Some parents who are good listeners are self-centered.(D)
(E) Fewer self-centered parents than generous parents are good listeners.
还是不理解为什么选D, 请牛人指教
这道题我也狂想了N久,用公共元素直推发的话就没对的了。排除ABE很容易,关键是CD。后来想可能是这样的,不知道这么想对不对
good listeners里有一部分是good parents,而不都是,也不保证是most。而good parents里有一些是self-centered.所以C的most原文没提到错了。而D的some刚好对了。因为some的数量比较松散,可多可少,限制小。
也符合费费的原则,归纳题绝对词一般都是错的。
