Passage Summary: Bad drivers with lots of tickets need to be punished with either jail or classes, but classes should only be used if they actually help, and they almost never help people who already have a lot of tickets.

Reasoning: Serious offenders with many demerit points must receive jail or re-education; re-education is only appropriate if it works; however, it almost never works for drivers with many points.

Analysis: This stimulus sets up a conditional requirement: punishment is mandatory (jail or re-education), but one of those options (re-education) has a strict prerequisite (it must be likely to work). Since the final premise tells us that re-education is almost never effective for this specific group, the logical path narrows significantly. We should look for an answer that suggests jail is the only remaining viable option for the majority of these specific offenders. It’s a classic process of elimination based on the provided rules.
