Question Stats:

82% (03:07) correct 18% (02:02) wrong based on 11 sessions
A recent research study of undergraduate students analyzed the effects of music on human emotions. Each of the 200 participants attended at least 1 two-hour concert of classical music per week over the course of 12 weeks of their spring semester. At the end of the experiment, all of the students filled out a questionnaire assessing their emotional state. Based on the results of the questionnaires, all of the 10 students who attended the greatest number of concerts reported lower stress levels and higher satisfaction with their lives. Also, most of the 20 students who attended the
fewest number of concerts reported below-average levels of emotional comfort.

Which of the following must be true based on the evidence presented above?
Most of the 200 participants improved their emotional state and lowered their stress levels.

During each week of the experiment, the participants spent at least 2 hours less on their academic work as a result of concert attendance.

Listening to classical music for at least 2 hours per week improves the emotional well-being of the majority of young adults.

More than 6 participants attended at least 14 concerts during the course of the experiment.

At least some of the students participated in the study in order to gain free access to classical concerts.

Please post answers with explainations.

Premise 1: A recent research study of undergraduate students analyzed the effects of music on human emotions.
Premise 2: Each of the 200 participants attended at least 1 two-hour concert of classical music per week over the course of 12 weeks of their spring semester.
Premise 3: At the end of the experiment, all of the students filled out a questionnaire assessing their emotional state.
Premise 4: all of the 10 students who attended the greatest number of concerts reported lower stress levels and higher satisfaction with their lives.
Premise 5: Also, most of the 20 students who attended the fewest number of concerts reported below-average levels of emotional comfort.

Most of the 200 participants improved their emotional state and lowered their stress levels.
Premise 4 and 5 together account for 30 students there is still 170 student who cannot be accounted. So not true.

During each week of the experiment, the participants spent at least 2 hours less on their academic work as a result of concert attendance.
There is no proof of this, more over even experiment might be part of course work.

Listening to classical music for at least 2 hours per week improves the emotional well-being of the majority of young adults.
Just on basis of Premise 4 (data of 10 students), it is too much to conclude this.

More than 6 participants attended at least 14 concerts during the course of the experiment.
Premise 2 said all student attended at least 2 hour concert. As per Premise 4 at least 10 student watched more than concert than other. Quite safe to assume that these 10 students attended at least 2 concerts each. So 6 students did attended more than 14 concerts.

At least some of the students participated in the study in order to gain free access to classical concerts.
No proof given in the passage.

I personally think this question would never show up on the GMAT, but here is my take on it.

The key is to recognize that the passage refers to 3 groups of people who attended different numbers of concerts - the 'greatest' group of 10, the 'not mentioned - middle' group of 170, and the 'fewest' group of 20.

Combine this with the fact that the students at minimum have to attend 12 concerts (1 per week) we get =>
Fewest group => at least 12 concerts
middle group => at least 13 concerts
greatest group => at least 14 concerts

If we know the greatest group have attended at least 14 concerts, then we know D) is true.

Good point abhijit.

I concur with your approach.
Here is POE approach that also narrows down to the answer:

Most of the 200 participants improved their emotional state and lowered their stress levels. [Nothing clearly alludes to this point – all the argument mentioned is all of the major participants – eliminate it]


During each week of the experiment, the participants spent at least 2 hours less on their academic work as a result of concert attendance. [interesting academic work was not even mentioned – by the by who said attending the concerts has negative effect on the academic performance – bye bye]

Listening to classical music for at least 2 hours per week improves the emotional well-being of the majority of young adults. [Argument mentioned one hour program and moreover, If this is true then we won’t see any unrest in youth – definitely not the choice]

More than 6 participants attended at least 14 concerts during the course of the experiment.

At least some of the students participated in the study in order to gain free access to classical concerts. [Again nothing in the argument mentions about it – eliminate it

Seems numbers magic is playing in the argument – D

OA is D, thanks abhijeet for the good reasoning. I also think that this kind of questions can never occur on the GMAT.

I agree. I go for D with the same reasoning
