### HideShow timer Statistics

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.

Conclusion: If a person is an expert on a musical instrument, that person must have practiced for at least three hours each day

The author further says the basic condition "If people practice a musical instrument for three hours each day, they will eventually become experts on that instrument"

Hence the argument rests on 3 hours of practice as the necessary condition to learn a musical instrument. Answer option C/D/E are all out of scope. A and B are the closest. If you look at B closely, it mentions practicing less than three hours, a condition that is not in the purview of the argument. Hence the answer option A.

I will go for A.

Why?
CDE can be eliminated easily as they are not even related to subjects in the arguments.

The choice is between A and B.

Statement says "f people practice a musical instrument for three hours each day, they will eventually become experts on that instrument" or if I can rephrase, it means "if A, eventually B"

It does not talk about "if not A, then B or not B". Thus A.

I would go for B as clearly speaks about the flaw. It might be possible for few to become an expert with less than 3 hours practice everyday.

Now OA please?
