Audit a short quiz for avoidable unfairness

Review [QUIZ], [LEARNING OBJECTIVES], and [LEARNER CONTEXT]. For each item, map the objective, required knowledge, reading or cultural load, potential ambiguity, and suggested revision. Then produce a revised quiz and answer key without lowering the core skill demand. Do not infer a learner's ability from group identity or invent curriculum requirements. Check that each revised item has a defensible key or a rubric accepting multiple valid answers, uses taught material, and still measures its intended objective.
