How would A not help, if there are people with high cognitive skills already in the experiment wont the sample of the population be affected?
Person A does not know the gameplay, he will have to learn the skills
Person B who is professional and has high cognitive skills will easily nail the game.

Also, as the solution says

Moreover, knowing whether professional games with high cognitive flexibility play the game would not help determine whether the game caused such high cognitive flexibility among those gamers or something else did.)


Thus the result is affected because of high congnitive fexibility as there can be other factors. Thus knowing if such player are part of game is relevant according to me.

Can you please correct me

I think this is a poor-quality question and the explanation isn't clear enough, please elaborate. How would A not help, if there are people with high cognitive skills already in the experiment wont the sample of the population be affected?

Person B who is professional and has high cognitive skills will easily nail the game.

I think you misunderstood option (A) - it doesn't say "whether professional gamers were among the volunteers". It says something to the effect of "whether professional gamers played these games during their early years."
These professional gamers have nothing to do with the experiment and volunteers. Now review the argument again and Bunuel's solution too. It will all make sense.

I think the language of A is quite twisted which says that pro gamers who had Congnititve ability played the 2 types of games in the question and if this is what A means then it is relevant..but i got from the above discussion that I misunderstood so now it is clear!

Thanks KarishmaB, I did commit this mistake and judging by comments, few others did too.

Bad question and clearly why 99% have gotten it wrong when it is actually an easy question. (A) = played the games - most people are interpreting it as professional gamers being part of the volunteers... and logically this is the case.This is a very bad question
Bunuel wrote:
In order to find out the effect of computer gaming on 'cognitive flexibility' – ability to switch between tasks – researchers recruited two groups having equal number of volunteers. One group played a real-time strategy game, which requires frequent decision making and high level of organising skills, while the other a life-simulation game, which does not require much memory or many tactics. The two groups played their respective games for at least forty hours over six weeks.

Each of the following may be important to know before arriving at a conclusion regarding the influence of playing computer games on cognitive flexibility except:


A. Whether professional gamers who had high cognitive flexibility played the games.
B. How many participants in each group have been playing strategy games before the experiment?
C. How was the performance of the participants on cognitive flexibility tests before the experiment?
D. How was the food habits and sleeping habits of the participants during the experiment?
E. How was the performance of the participants on cognitive flexibility tests after the experiment?

Thank you for the feedback!

I’ve searched for forum Discussions and I see that some of the experts had reservations about this question as well so I’m going to go ahead and remove remove it from the tests. This means if you have taken this question, you will still be able to see your history but people will not be able to take this question as a part of tests or custom tests.

https://gmatclub.com/forum/in-order-to- ... 10911.html

Thank you for your help. As a thank you and for helping us find the bug, I will be providing you with two weeks of additional access to the GMAT Club tests.
