讨论：一道逻辑题目

说一个社区学校没钱了，于是校长发动大家筹资，并答应达到多少多少钱就染绿色的头发。后来学生通过在社区打工赚到了这么多的钱，问Assumption
一个选项说很少有人排斥拿校长开玩笑
一个说社区的人愿意出钱给学校 然后我选了这个待讨论

一直没有明白这句话的逻辑意义,请nn指点为什么选后者

If people in community would not be willing to donate money to the school, then even if the principal says he will walk naked, the students won't be able to collect enough money.

Thus the willingness of the community to help the fund-raising effort of the school is a necessary assumption for the conclusion that the students eventally would raise enough money from the community.

如果社区的人愿意出钱，学生还用打工吗？
