CONTEXT:
{context}

TASK TYPE: `match_letters`

QUERY:
{query}

This is a matching / multiple-choice letter task. Each QUERY item asks you to choose among labeled options (A, B, C, ...).

How to solve:
1. Extract the mapping or rule set from CONTEXT.
2. For each numbered QUERY item, evaluate the options against that rule set.
3. Return only the chosen option letter (A, B, C, ...), uppercase.
4. Do not repeat the option text, explanations, or punctuation around the letter on the answer lines.

Draft, then check you have one letter per QUERY item. Finally write a line that says exactly `FINAL ANSWERS:` and, below it, one bare letter per item in QUERY order — no numbering, no quotes, no extra text.
