it's option B........ 





Student: 3/9/2010 6:23:08 PM 

is the answer wrong? I thought option B is enough since you can already tell from it that it is impossible to allocate 2 hours for U and T for the meeting 





Student: 3/11/2010 9:12:28 AM 

I agree I think B should be the correct answer. 





Student: 3/22/2010 2:13:03 PM 

Okay you have to in precise order for these questions
a) tells you 2 of the 4 could meet so it does not answer the questions about all 4 (so you can eliminate a, d)
b) tells you 1 person has 1 hour free and the other person has a different 2 hour opening for a meeting but because it does not reference the other two people it cannot answer the questions (eliminate b)
Now if you combine both A&B you see it answers the question: "can the 4 commuters meet for a meeting on Friday for 2 hours"
So, C is your answer.

the ans is B 





Student: 6/10/2010 3:38:55 PM 

C is your answer 





Student: 6/22/2010 3:38:45 PM 

Can someone please provide justification for the answer (option C). I think it should be option B since it is clearly evident that a 2hr common window for all 4 commissioners is not available on Friday.

C is the correct response.

Option should be ;B
Statement B itself satisfies that between T & U meeting is possible between 11 to 12 which is 1 hr but meeting is needed to be scheduled for 2 hr so there is no need to check statement 1 coz meeting cannot be scheduled.

Student: 11/16/2010 12:29:12 PM 

I think E is the right answer. The commissioners don't have two hours time. 





Student: 11/16/2010 1:48:26 PM 

b, as meeting has to be amongst 4 ppl.. and two of them cannot meet simultaneously for two hours.. so is clear... statement 2 is sufficient.. 





Student: 1/9/2011 1:32:26 PM 

B is the answer! 





Student: 1/29/2011 7:31:27 AM 

i thnk ,,i'll go wid same.. both a & b r nt alone r nt sufficient..






Student: 1/31/2011 4:03:39 AM 

C is the answer






Student: 2/1/2011 2:15:47 PM 

answer is C because option 2 tells us only 1 hr i.e 11 to 12 but we need two hrs and option c tells us free hr as afetr 12 so the meeting cannot be scheduled 





Student: 4/24/2011 6:12:55 PM 

Answer should be C.
Question asks if all the 4 commissioners have time. So have to look at statement A and B both.

IS THE ANS WRONG...BCZ U ALL READY ALLOCATED...S,T,U HAVE ONLY 2HR FREE SLOT...THEN HOW CAN U SAY ...THAT TIME

Is there a 2hour period on Friday that is open for all four commissioners? Yes. All the four have a 2 hr open period, each but does not match with open perios of one anothers. A alone cannot answer and not enough. B alone cannot answer and not enough. But if we compare A & B, we can say that all the four have atleast 2 hrs of open period, but then they dont have a common 2 hrs open period. But this definitely answer the question"Is there a 2hour period on Friday that is open for all four commissioners?" and the answer is No. So the answer for this is C. 





Student: 2/13/2012 3:40:07 PM 

B 





Student: 2/13/2012 7:27:21 PM 

Yea, definitely should be B. If you already know that T and U can't meet then you know that the meeting of 4 can't happen.

"Is there a 2hour period on Friday that is open for all four commissioners?"
It's vague. While the common sense suggests that we look for a 2hour period 'common' to all 4 commissioners, the question above doesn't ask for a 'common' 2hr period open period. All it asks is whether all 4 commissioners have a 2hour open period. With that, C is the answer.
