Explanation:

Let’s break down the options:

- Option 1: Gagnon v. Scarpelli (1973)

This was a Supreme Court case about due process rights for parolees facing revocation. It’s a landmark case, but it’s not about the actual rules parolees must follow.

- Option 2: Absconder

An absconder is someone who flees or hides to avoid supervision (like parole or probation). It’s not about the rules themselves, but what happens when someone breaks them.

- Option 3: Conditions of Parole

This is the real answer. "Conditions of parole" are the specific rules parolees have to follow, like not using drugs, not associating with felons, reporting to a parole officer, and so on. Break these, and you risk going back to prison.

- Option 4: Split Sentence

A split sentence combines jail time with probation or parole. It describes a type of sentence, not the rules governing behavior on parole.

So, the rules that parolees must follow? That’s 100% "conditions of parole."
