Sarah: Some schools seek to foster a habit of volunteering in their students by requiring them to perform community service. ███ █████ █ ██████ ███ ███ ████ ██████ ██ ██ █████████ ███ ███ ██████ ███████████ ███ █████ ███ █████ ██ ████████████ ██████ ██ ████ ██ ████ ████ ████████ ██ █ ██████ ███ ███ ███ ███ ███████████ ███ █████████ █████ ██ ██ ███ ████ ██████ ███ ███████ ██ ███████

Sarah has just claimed that the policy some schools have of requiring students to do community service cannot succeed in fostering a habit of volunteering. This is based on the premises that if someone is forced to do something, they haven't volunteered for it, and that, if someone hasn't yet volunteered for something, they can't be said to have a habit of volunteering.
Paul disagrees with Sarah's conclusion: in other words, he believes the policy these schools enforce can, at least in some cases, succeed in fostering a habit of volunteering in students. As evidence, he points out that sometimes when students are forced to participate in community service, they enjoy it enough that they subsequently actually volunteer to do something similar.

Correct. Sarah makes it clear that "this policy" — i.e., the policy of requiring students to perform community service — has "no way" to "succeed by itself": i.e., on its own, requiring students to perform community service will never foster a genuine habit of volunteering.
Paul, meanwhile, thinks forcing students to perform community service now can bring about a genuine habit of volunteering in some students later on. Thus, unlike Sarah, he thinks there are some situations where the policy of requiring students to perform community service "can clearly be said to have fostered a habit of volunteering."
