This is a draft option you can keep, modify, or replace. The questions themselves are unchanged from the live baseline; the commentary below is an ID-side alignment review only. Content correctness is out of my lane — please flag any stats / discipline claims that need a content-side check.
NOTE: Per-question correct/incorrect feedback has been added on every question (concept-anchored to the relevant MLO, plain language). This is itself an ADD against the live baseline — flag if you'd prefer the old no-feedback shape.
