Passage Summary: To get a new course approved, it has to go through the committee or the Dean. The Dean only has one proposal, and every proposal the committee has is for an advanced class. Also, all advanced classes will require prerequisites starting next year.

Reasoning: Approval requires a proposal to the committee or Dean. Dean has one proposal. Committee has only upper-level proposals. All upper-level courses need prerequisites.

Analysis: This is a formal logic puzzle that requires tracking the origin of new course proposals. Since the committee only has upper-level proposals and all upper-level courses need prerequisites, any course approved via the committee must have a prerequisite. The only potential exception is the single proposal submitted to Dean Wilson. Therefore, the facts dictate that at most one new course could be approved without a prerequisite.
