Critics of sales seminars run by outside consultants point out that since 1987, revenues of vacuum cleaner companies whose employees attended consultant-led seminars were lower than revenues of vacuum cleaner companies whose employees did not attend such seminars. The critics charge that for vacuum cleaner companies, the sales seminars are ill conceived and a waste of money.

Which of the following, if true, is the most effective challenge to the critics of sales seminars?

(A) Those vacuum cleaner companies whose sales were highest prior to 1987 are the only companies that did not send employees to the seminars.
(B) Vacuum cleaner companies that have sent employees to sales seminars since 1987 experienced a greater drop in sales than they had prior to 1987.
(C) The cost of vacuum cleaner sales seminars run by outside consultants has risen dramatically since 1987.
(D) The poor design of vacuum cleaner sales seminars is not the only reason for their ineffectiveness.
(E) Since 1987, sales of vacuum cleaners have risen twenty percent.

Ans : A

這題好難選喔!!!

不過我在想會不會是因為a說1987年以前賺最多錢的是那些沒去seminar的

那現在1987年後這些沒去seminar的卻也沒賺那麼多錢了,只是比有去seminar的多,但不像1987年前是賺最多

所以表示其實影響賺錢還有其他的原因,不只seminar,所以有一點weaken的味道

真難,看到a完全百分之兩萬不會選
