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.
sticky
Misconception. Sticky bit shows as t in other position, not s in owner.
Remedy. Memorize position: s in u=setuid, s in g=setgid, t in o=sticky.
setgid
Misconception. setgid shows as s in GROUP position, not owner.
Remedy. Mnemonic: 4=setuid (user position), 2=setgid (group position), 1=sticky (other position).
