I do not get the answer to this CR question....can anyone help to explain? Thanks!

A vicious cycle ensues when students cheat on exams. Grade inflation drives schools to raise standards, which increases the pressure on non-cheating students. In turn, this drives even more students to start cheating on exams.

The vicious cycle described above could not result unless which of the following were true?

A. When standards rise, it tends to give students an incentive to try raising their grades honestly.

B. The ways to expel cheaters and counteract grade inflation are achievable through various means, but some single out innocent students, and effectiveness rates fluctuate yearly.

C. When schools set grades standards to evaluate student performance, they do not adequately allow for cheating by some percentage of students.

D. No regular cheaters will be discouraged from cheating by a lowering of the standards, unless stronger penalties are also added.

E. All students will begin cheating when the standards reach the same level.

The answer is C...but WHY?

Thanks!
