+# MMRB Multi-Image Reasoning Heuristics
+
+## Cross-Image Alignment
+- Track the role of each image by its index and compare evidence across all referenced images before deciding.
+- When the question depends on sequence, correspondence, or retrieval, verify the relation between images instead of judging each image independently.
+
+## Option Elimination
+- For multiple-choice tasks, compare all options and reject choices that match only part of the visual evidence.
+- If options differ by a small visual detail, use the most discriminative cue rather than a coarse scene impression.
+
+## Open Answers
+- For open-ended tasks, give the shortest answer that is fully supported by the combined images.
+- Preserve exact entities, attributes, counts, and directions when the images support them directly.
+
+## Final Answer
+- Output only the final answer inside <answer>...</answer>.
