Answer:
The last one "When students perform poorly test after test after test, not being able to gain acceptance into a college of their dreams or graduate from high school (and so on i'm sorry i'm too lazy to write the whole thing.)
Explanation:
A slippery slope argument involves an acceptance of a succession of events without direct evidence that this course of events will happen.
Basically in the one I put the author tries to say that any kid that fails their tests and isn't accepted to their dream college etc will drop out and suffer from low self esteem but he shows no direct evidence to prove this.
