The author concludes that some students with part-time jobs do not walk to school. His reasoning is that every student who walks to school goes home for lunch. Or, in contrapositive form, that all students who don’t go home for lunch don’t walk to school.

The conclusion is about students with part-time jobs, but they aren’t mentioned in the premise. We need to bridge this gap to reach the conclusion that some students with part-time jobs do not walk to school.

By taking the contrapositive of the premise, we inferred that all students who don’t go home for lunch don’t walk to school. So, if at least some students with part-time jobs don’t go home for lunch, then some of them wouldn’t walk to school. This would guarantee the argument’s conclusion.

This can’t be correct, because it tells us about some students who don’t have part-time jobs. Our conclusion is about students who do have part-time jobs. A “some” statement’s contrapositive isn’t automatically valid. So this tells us nothing about students with part-time jobs.

This doesn’t help us reach our conclusion, because all it lets us infer is that some students with part-time jobs go home for lunch. We want to conclude that some students with part-time jobs do not walk to school.

Every student who doesn’t go home for lunch doesn’t walk to school. So, if some students with part-time jobs don’t go home for lunch, some students with part-time jobs don’t walk to school. Note that “some” is bidirectional: saying some As are Bs is equivalent to saying that some Bs are As.

This doesn’t mention students with part-time jobs, so it can’t be correct. We need an answer that bridges the gap between the premise and the conclusion.
