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.

B: reload ~/.bashrc
Misconception. No such command.
Remedy. source is the canonical name.
C: bash ~/.bashrc
Misconception. Spawns subshell, does not affect current.
Remedy. Subshell exits and changes vanish.
D: exec ~/.bashrc
Misconception. Replaces shell; usually not what you want for a config file.
Remedy. exec replaces the process image.
