How will the right answer fit in terms of support and conclusion?

Only the right answer will be a conclusion guaranteed by support given in the passage.

Highlight the main conclusion in the passage, if there is one:

There is no conclusion in the passage. The right answer will be the conclusion.

Committee chairperson: [SUPPORT]. [SUPPORT], and [SUPPORT]. [SUPPORT].

You may not be clear on whether parts of this are support or background until you see the answers, so best to just get on with careful mapping and eliminating. You know you can knock out any answer that brings in something new, and any answer that uses stronger wording than the passage uses.

Map the wording of the answers to the wording of the passage:

(A) If there are no new upper-level courses…

All the info in the passage is about when there are new courses. We have exactly zero info about what happens if there aren’t any.

(B) …will have been approved.

We have no info about what courses will be approved. We only know that a course won’t be approved “unless a proposal for it has already been received”.

(C) If there is more than one…

This is the once-in-a-decade question that relies on four (4!) separate pieces of support. It’s like this: There’s “only one new course” that might not have a prereq, the one Wilson got. That’s because all the others went to the committee, and they’re all “for upper-level courses”, and “all upper-level courses will have prerequisites”. So if there’s more than that one new course from Wilson, “at least one” is gonna have a prereq.

(D) …then all courses…

Stop! The passage only gives rules about “new” courses and “upper-level” courses. We have no info about “all courses”.

(E) …will have been approved.

See (B).

(C) is the correct answer.
