Passage Summary: Sarah thinks you can't force someone to become a volunteer because volunteering is by definition not forced. Paul argues that the experience of being forced might actually make someone want to do it for real later on.

Conclusion: Sarah's assertion that mandatory community service cannot foster a volunteering habit is incorrect.

Reasoning: The initial forced activity can lead to a genuine interest, resulting in the student choosing to volunteer of their own accord later.

Analysis: Paul's strategy is to provide a counterexample that undermines Sarah's absolute claim. While Sarah focuses on the logical definition of 'volunteering' at the moment the act occurs, Paul focuses on the causal sequence of events. He shows that a 'forced' start can be the catalyst for a 'voluntary' habit. When evaluating the method, look for an answer that describes how a specific scenario is used to disprove a general impossibility claim. It’s a classic 'it can happen because here is a case where it does' rebuttal.
