### 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.

OA is A

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.

This does not mean that the consultant-led seminars caused the revenues to go down.
It is possible that the vacuum cleaner companies whose revenues were already high , did not attend the consultant-led seminars as they already had the expected performance.

Check teh rest of the statement..THey just donot fit in..

B -> says that seminars caused drop in sales i.e support critic calim
C,D - > out of scope
E-> strengthens the critics claim furthey by implying that when the overall sales is up, the seminar attended companies' sales are down.

A is the only fit answer which says the revenues of the companies are higher becoz of thier quality i.e traditionally higher ssales..

The answer is A and here's another way to reach the conclusion.

The question is essentially a "weaken" question which would weaken the critics' argument.
There are several ways to weaken an argument, especially when there is a cause-effect structure.

1) Show that the cause occurs but the effect does not.
2) Show that the effect occurs but the cause does not.
3) Show that there is an alternative reason for the effect happening.
4) Show that there are problems with the data/bias.

A shows that there is bias towards the sample, and thus it weakens the argument.
