### HideShow timer Statistics

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.

Maybe - if that is the case then the seminar vacuum companies MAY have gained revenue but overall still lower than the companies that had high revenue.

(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.
Supports the critic so NO.

(C) The cost of vacuum cleaner sales seminars run by outside consultants has risen dramatically since 1987.
Out of scope.

(D) The poor design of vacuum cleaner sales seminars is not the only reason for their ineffectiveness
Out of scope.

(E) Since 1987, sales of vacuum cleaners have risen twenty percent.
Doesn't say if it affected all companies and even if it does we still dont know which company had higher revenue before the even increase...

This one is tricky too. My confusion is that A says "sales were highest prior to 1987" while the argument says "since 1987, revenues....."
How can we compare prior to 1987 against after 1987??
But again, there are no other better answers.
