Misconception bank
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.
A: ops
Misconception. That is double-quoted behavior.
Remedy. Single = literal.
C: (empty)
Misconception. Single quotes do not blank the value.
Remedy. Literal output of what is between quotes.
D: Error: unbound variable
Misconception. No errors — single quotes make it literal.
Remedy. set -u would error, but default shell does not.
