This passage links the number of students who are DISCIPLINED to the number of students who CHEAT.
The correct answer must BREAK this link.
Answer choice A: As they move up in grade, students learn how to cheat without getting caught.
This answer choice offers AN ALTERNATE REASON that fewer studems in the upper grades are DISCIPLINED for cheating: they have learned how to AVOID GETTING CAUGHT.
Thus, it is entirely possible that MORE STUDENTS in the upper grades are CHEATNG, breaking the link between the number who are DISCIPLINED and the number who CHEAT.

The correct answer is A.

The correct answer is A.

Mitch,

Why are we considering students who are DISCIPLINED and students who CHEAT as different ?

Doesn't the question say that students who are disciplined to cheat ?

Not really sure how did you make these two entities independent ?

Because DISCIPLINED is not the same as CHEATING.
The correct answer states that older students who CHEAT have learned how to avoid GETTING CAUGHT.
Since these older students are NOT CAUGHT, they are not DISCIPLINED for cheating, even though they are in fact CHEATING -- weakening the conclusion that, as students grow older, they realize the need for serious study and stop cheating.

Thanks Mitch, get the difference now
