单项选择题

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 eligibly for the raffle, most of the employees must have participated in fewer than four of the scheduled events.
Which one of the following arguments exhibits a flawed pattern of reasoning most like that exhibited by the argument above

A．Only third-and fourth-year students are allowed to keep cars on campus. Since one quarter of the third-year students keep cars on campus and one half of the fourth-year students keep cars on campus, it must be that fewer third-year students than fourth-year students keep cars on campus.

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.

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.
