800分里的，有点儿没绕过来

Steve and JoAnne are both members of a certain club, though they are not speaking to each other. Cecily, the club president, is appointing members to the fundraising committee, but she has resolved that she will not appoint anyone without his or her explicit consent. Steve tells Cecily, 'I will not consent to appointment on that committee unless I know whether JoAnne is to be a member of it.' And JoAnne says, 'I will not consent to be a member of that committee unless I know whether Steve will be appointed to it.' If all three of these people stick by these resolutions, then:

A) Neither of them can be appointed to the committee.

B) The situation described in the scenario cannot arise, because it is inherently incoherent.

C) They must either both be appointed or both be left out.

D) The committee may finally have one of them, both of them, or neither of them as members.

E) Either one of them can be appointed, but not both.

我觉得应该是A啊，因为S和J都要先知道对方是不是member才会consent，而C又必须得到consent才appoint，所以最后肯定是谁都不会被appoint啊！

请NN指点我错哪儿了呢？？？

"所以C在得到J的认可之前怎么会告诉S说她任命了J呢？"    C是告诉S她不任命J。而不是告诉J她要任命J

ROBERTCHU的理解是对的

噢，就是说C虽然不可以先任命，但是可以先说不任命！我好笨噢！
