请教一道XDF的逻辑

sarawang521 · 发表于 2010-4-5 09:12:11

现在正在看XDF的逻辑笔记，但是有些只有题目，没有答案，不知道对不对~ 请教下各位了~
例2.To be mentally healthy, people must have self-respect. People can maintain self-respect only by continually earning the respect of others they esteem. They can earn this respect only by treating these others morally.

Which of the following conclusions can be properly drawn from the statements above?
(A) People who are mentally healthy will be treated morally by others.
(B) People who are mentally healthy will have treated morally those they esteem.
(C) People who are mentally healthy must have self-respect in order to be treated morally by others.
(D) People can expect to be treated morally by others only if they esteem these others.
(E) People who have self-respect seldom treat morally those esteem.

现在纠结在C和D上。因为NOTES上讲by A in order to B 表示A 推出B（A→B）；only if A then B 表示只有A才有B（ B→A）；
自己的逻辑本来打算放弃掉了，可是下了XDF的笔记，觉得还不错。请问谁有XDF笔记，带答案的啊~　可不可以发给我啊～　　不胜感激！！！

顺序是这样的
先treating these others morally-----才能earn this respect -------所以maintain self-respect ---------最终mentally healthy

所以选b
