### HideShow timer Statistics

7. To become an expert on a musical instrument, a person must practice. If people practice a musical instrument for three hours each day, they will eventually become experts on that instrument. Therefore, if a person is an expert on a musical instrument, that person must have practiced for at least three hours each day.
Which one of the following most accurately describes a flaw in the reasoning above?
(A) The conclusion fails to take into account that people who practice for three hours every day might not yet have reached a degree of proficiency that everyone would consider expert.
(B) The conclusion fails to take into account that practicing for less than three hours each day may be enough for some people to become experts.
(C) The conclusion fails to take into account that if a person has not practiced for at least three hours a day, the person has not become an expert.
(D) The conclusion fails to take into account that three consecutive hours of daily practice is not recommended by all music teachers.
(E) The conclusion fails to take into account that few people have the spare time necessary to devote three hours daily to practice.

Between A and B.......I will go for B

I think A is not flaw because the argument takes care of this case by the word â€œeventuallyâ€

(A) The conclusion fails to take into account that people who practice for three hours every day might not yet have reached a degree of proficiency that everyone would consider expert.

They might not have YET reached there..but would in all likelihood get there someday if they continue with the regimen....Does not weaken.

(B) The conclusion fails to take into account that practicing for less than three hours each day may be enough for some people to become experts.

Right..Weakens because it directly attacks the evidence for becoming expert one needs to practice at least three hours each day.

(C) The conclusion fails to take into account that if a person has not practiced for at least three hours a day, the person has not become an expert.

Yeah..and will never become one if the stem is anything to go by..

(D) The conclusion fails to take into account that three consecutive hours of daily practice is not recommended by all music teachers.

Well, in that case the music teachers can go climb a tree! Jokes apart..this is a typical flaw when an attempt to prove or disprove the credibility of an argument is made by citing expert opinions which on GMAT questions is a complete taboo IMO.

(E) The conclusion fails to take into account that few people have the spare time necessary to devote three hours daily to practice.

Yeah, I can surely empathize with these souls!!

Oh good...I would have gone with B too.....
Therefore, if a person is an expert on a musical instrument, that person must have practiced for at least three hours each day.
this can be weakened by saying that some people can reach am expertize level with less than 3 hrs of practice...
which is B

Agree with you on the POE, but not on the final answer.

give me B!

The conclusion says: Therefore, if a person is an expert on a musical instrument, that person must have practiced for at least three hours each day.

This is a conditional conclusion. Here's a tip: On such conclusions, assume the condition is true . i.e The person is an expert. Now see how the conclusion can be true but the premise false. (As in any other weaken question)

In A, the premise is true (practise >= 3hours), but the conclusion is false (not an expert) . The exact opposite of what ne need!
