Question text *

Question text is required.

Matching pairs *

Prompt-answer pairs — each pair has a left-side prompt and its correct right-side answer. Distractor answers (right column only, no matching prompt) are optional, extra items that increase difficulty. All right-column values (matched + distractor) are shuffled when presented to learners.

Prompt (left column)	Answer (right column)




Distractor

At least 2 prompt-answer pairs are required. Both the prompt and the answer in each pair must be non-empty; distractor values must be non-empty if added (AR#1).

Scoring: each correctly matched pair earns an equal share of the total points — floor(correct_pairs / total_pairs × points). Distractor rows are excluded from the pair count.

Answer explanation (optional)

Points *

Total marks this question contributes. Each of the 4 matched pairs earns an equal share.
