Steve and JoAnne are both members of a certain club, though [#permalink]
 10 Jun 2006, 18:00
Question Stats:
0% (00:00) correct
 0% (00:00) wrong based on 0 sessions
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.
My guess: A (If you guys see it without selecting can you please let me know, how someone usually hides it)

Re: CR - Steve and JoAnne [#permalink]
11 Jun 2006, 05:09
I would go for A
B - > is eliminated outright cos it does not address the situation
C - > is eliminated as either of the persons will not consent without the knowledge of the other, and they cannot be enrolled before they consent.
D -> is eliminated again on the same grounds as C as there will never be a situation of either one of them as long as they stick to thier stands.
E - > is again eliminated as pre condition to appointment is consent, and precondition to consent is information about the other person which will not be available.

I believe its C too...
The two members are not talking to each other, which doesn't mean they cannot serve on the committe.
Both the members just wants to know if the other will be serving on the committe or not before he/she decides. None of them say they won't join the committe if the other one does.

Will go with D.
From the passage we know that "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.' " Now this tells us that both their consent iS dependent on the information not whether somebody is on the commitee or not.
For example We know that steve won't give a consent unless he knows whether Jaon is on the commitee. Lets say he gets to know that but we don't know whether he will give a consent based on that information or not. That is he may choose to serve or may not choose to serve.
Hence D

Steve: don't know whether JoAnne is in => no consent
JoAnne: don'k know wheter Steve is in=> no consent
A => B means not B => not A (As can be seen in the Sticky)
Steve: consent => know JoAnne is in
JoAnne: consent => know Steve is in
this means that, if steve consent, JoAnne is already in
if JoAnne consent, Steve is already in.
So, both should be in, or both should be out as stated in C.

I think both Steve and Joanne never said that they will disapprove each other's memebership...
But they still stick to their resolution: not to talk to each other..
Lets wait for the OA

I believe its D.
Carefully read the statements.
Steve tells Cecily, 'I will not consent to appointment on that committee unless I know whether JoAnne is to be a member of it.'
JoAnne says, 'I will not consent to be a member of that committee unless I know whether Steve will be appointed to it.'
We don't know the response of any of them after telling them about the selection of other person.
After president asks any of them(With both options when other person is selected and not selected) they may say "YES" or "NO".
There are multiple situations:
---------President Tells----------------
Steve Selected---JoAnne Selected---Steve's Response---JoAnne's Response---Final Selection
-------Y--------------------Y--------------------Y-----------------------Y----- --------------Both
-------Y--------------------Y--------------------Y-----------------------N----- --------------Steve
-------Y--------------------Y--------------------N-----------------------Y----- --------------JoAnne
-------Y--------------------Y--------------------N-----------------------N----- --------------None
Same way there are 12 more cases but outcomes will be same.

Cannot be E because, to get JoAnne's decision, you need to know John's decision, which in turn depends on JoAnne's decision. Chicken and egg situation. Ditto if you want to get John's decision first.
Should be A.
