   French Literature 205 is a required course for

   We don't want new ideas in Sufficient Assumption answers. We just want them to patch up the existing ideas. Learning that French Literature 205 is required for French Literature majors wouldn't help us in any way to prove that certain people aren't French Literature majors.

   Only biology majors are allowed to take

   It's incredibly rare that this happens, but this answer basically restates a premise. This is technically still distinct, because this is a timeless rule. The premise was about the students who are currently taking Biology 218, but conditionally they're going to look the same: Biology 218 ? Biology major

   There are more biology majors than there are

   The total quantity of Biology vs. French Literature majors is irrelevant to us. It wouldn't make any difference if Biology had more / less / the same. This won't help us prove that some French Literature 205 students aren't French Literature majors. We already know that they're Biology majors. We just need to know if they could also be French Literature majors. There could be some students who are double majors (Biology and French Literature), whether there are more Biology, same Biology, or less Biology students overall.

   There are more French-literature majors than there are

   The total quantity of Biology vs. French Literature majors is irrelevant to us. It wouldn't make any difference if French Literature had more / less / the same. This won't help us prove that some French Literature 205 students aren't French Literature majors. We already know that they're Biology majors. We just need to know if they could also be French Literature majors. There could be some students who are double majors (Biology and French Literature), whether there are more French Literature, same French Literature, or less French Literature students overall. So this fact doesn't help us assess the critical vulnerability of the argument: is it possible these bio majors taking French Literature 205 are also French Literature majors?

   It is not possible to major in both biology and

   Why this is right

   As we predicted, we needed to get from "we know these some students are bio majors" to "we want to prove that these some students are not French literature majors". This rule clearly justifies that move. It also matches the missing conditional link we sketched out in the setup: Biology major ? ~French literature major

   Skill tested: Sufficient Assumption · how this choice captures the argument's function is the move to repeat next time.
