Each row below is a plausible wrong answer, the thinking that produces it, and the remedy that corrects the misconception. These are the foundation of the multiple-choice framing and the targeted feedback a student receives after answering.

Misconception. Expects only top-level info; "jobs" prints the in-shell job table.

Misconception. Confuses jobs output with ps output.
Remedy. jobs uses [N]+, ps uses PIDs.
