Participants at a continuing legal education seminar were asked to evaluate the seminar schedule, location and topic selection to determine whether changes would increase attendance at next year’s seminar. A majority of the evaluations recommended that the seminar schedule be changed so that the sessions would be held from 8:00 a.m. to 4:00 p.m. instead of the current 9:00 a.m. to 5:00 p.m. schedule. Based upon the results of the evaluations, the sponsors of the seminar decided to change to an earlier schedule for next year’s program.

Which of the following selections, if true, would most prove the sponsors right in their decision to change to an earlier schedule next year?

(A) Approximately 85% of the people who received evaluation forms completed their forms and handed them in.
(B) Other seminar sponsors have made changes in their programs based on comments they have received in evaluation forms.
(C) About the same percentage of people attending the seminar wanted the earlier schedule as those who returned their evaluation forms.
(D) An earlier seminar schedule would make commuting easier for the participants.
(E) A significantly larger percentage of people who preferred the earlier schedule returned their evaluation forms than people who preferred the 9:00 a.m. to 5:00 p.m. schedule.

Imo C. A cannot be because the stimulus says majority of evaluations returned were FOR early timings. Now if 85 percent returned, majority could mean 43% of total attendees.

C says that people who returned evaluation approx equal FOR earlier timing. And stimulus already tells us that majority of the returned ate FOR early.this puts at least 51 % of the total

I am confused why D cannot be answer ? I thought in strengthening the argument additional information (outside of the question) can/should be used. so logic in D could support the conclusion.
C) tells that majority of People who wanted early schedule have still come to attend to class. So this point actually kind of discourages organizers to change timing because People prefer early timing but still majority of them actually attend

Please someone explain where should I correct my thought process :)

In A 85% returned - majority means more than 50% . so we get that out of all 100% people participating . around 43 % accepted to change. We don't know about rest . 15% of people.
It does't give adequate information to say that it strengthens.

Can you explain me What C is actually intending to say.
To my bad, I eliminated all options.

C states that - percentage of people who wanted schedule = Percentage of people who returned . ? what if only 10 % returned the forms. So it doesn't help much.
Need experts advice please.

Hi, after careful rereading I understood that it is actually stating that "majority of People attending the seminar wanted the earlier schedule." It strengthens the argument.
Hence answer is C.

Hence answer is C.


How did you arrive at the conclusion that a majority of people attending the seminar wanted the earlier schedule? I agree with your original concern, which is that the reading passage only states a majority of the evaluations recommended the earlier schedule. If the seminar only received 3 evaluations out of 500 participants, and 2 of the 3 wanted an earlier schedule, it would be true that a majority of the evaluations recommended the earlier schedule. However, probably not a great reason to change the scheduling based on 3 responses.

I think that "C" can be interpreted one of two ways, and could be written more clearly.

Interpretation 1: % of people who want the earlier schedule = % of people who returned their eval forms. We don't know what % of people returned their eval forms, so hard to say whether this strengthens or weakens the arguments

Interpretation 2: % of people who want the earlier schedule = % of people out of those who returned eval forms that also wanted earlier schedule. In this interpretation, we are confident that the majority of participants wants the earlier schedule, since we know a majority of people who returned eval forms wanted the earlier schedule. This interpretation takes out the need to know how many people returned their forms, since even if only 3 people returned, and 2 said yes, we know that the tiny sample is indicative of the broader group's preferences.

I'm just not sure how the reader is supposed to know that the author meant interpretation 2 as opposed to interpretation 1. It would be more clear if the answer said "About the same percentage of people attending the seminar as those who returned their evaluation forms wanted the earlier schedule".

Thoughts?

How is (C) the correct answer?

It says majority of the evaluations mentioned the change of schedule.

If the percentage of evaluation forms submitted were only 15%, then it wouldn't strengthen the conclusion.

An explanation by Manhattan --

the argument actually said "A majority of the evaluations recommended that the seminar schedule be changed." (italics added by me) This means only that of those evaluations collected, a majority indicated a preference for the earlier time. It tells us nothing about how many evaluations were collected, or what percent of the seminar participants returned them. For example, there could have been 100 people at the seminar, but only 3 evaluations collected. If 2 of those 3 indicated a preference for the earlier time, this premise would be truthful though misleading.

That's why three of the choices, (A), (C), and (E), deal with the response rate. To best support the decision to move to an earlier schedule, we need a choice that proves that the surveys accurately reflect the wishes of all the seminar participants. To decide between the seemingly similar (A), (C), and (E), read critically and mathematically.

(A) Seems to strengthen, but probably not. If 85% of the people who received evaluation forms completed their forms and handed them in, then at least 85%/2 = 42.5% ("a majority of the evaluations") want the earlier time. Worst case, the other 15% don't want the schedule changed. That means it's possible that a majority actually prefers the later time. We also must wonder whether "people who received evaluation forms" is the same as "people who attended the seminar"--did everyone get the forms in the first place?

(B) Other seminar sponsors are irrelevant.

(C) Strengthens, as it equates "people attending the seminar" with "those who returned their evaluation forms." In other words, if a majority of the evals prefered the earlier time, then a majority of all the participants want the earlier time.

(D) Ease of commute is irrelevant.

(E) Weakens, as it indicates that fewer people prefer the earlier schedule than the surveys indicate. In other words, the people who prefer the earlier schedule are over-represented in the surveys.
