Ok.
question says
If A, then and only then B.
Since B, so A.
Though other choices are close, but observe
At the company picnic, all of the employees who participated in more than four of the scheduled events, and only those employees were eligible for the raffle held at the end of the day. Since only a small proportion of the employees were eligible for the raffle, most of the employees must have participated in fewer than four of the scheduled events.
What abt ppl who participated in 4 events
Choice (E) says
(E) All of the swim team members who had decreased their racing times during the season were given awards that no other members were given. Since fewer than half the team members were given such awards, the racing times of more than half the team members must have increased during the season.
What about people whose timings remained same.
So reasoning is flawed.
Sidbidus, I could just as well say this:
(B)Only those violin students who attended extra rehearsal sessions were eligible for selection as soloists. Since two of the violin students were selected as soloists, those two must have been the only violin students who attended the extra sessions.
-- What about the other students who attended the extra rehearsal sessions but did not get selected?
(C) The only students honored at a special banquet were the band members who made the dean’s list last semester. Since most the band members were honored, most of the band members must have made the dean’s list.
--Well, I see that this flaw is not the same as the one in question.
(D) All of the members of the service club who volunteered at the hospital last summer were biology majors. Since ten of the club members are biology majors, those ten members must have volunteered at the hospital last summer.
--Again don't see the same kind of flaw as (B).
(A) does not look similar to me.
Why did you eliminate (B)?
