    "12312": "Solution claims 'Only letter L has a clear pair of perpendicular lines' (implies 2 perpendicular lines total), but stored correct answer is 3. Either the solution's analysis is incomplete (another letter also has a perpendicular line) or the answer key is wrong. Needs figure verification.",
    "12324": "Solution is truncated (ends with '...') and incomplete. The balance equation (3 cubes = 1080 g + 1 cube) yields 540 g per cube, but the stored correct answer is 360 g. The solution was heading toward 540 g before truncation. Possible figure misinterpretation or answer key conflict.",
    "12450": "Solution is garbled and self-contradictory. It first computes 12 correctly, then adds confused internal monologue: 'Wait — denominator is 8, so 2/3 cannot equal a fraction over 8 exactly.' The question likely renders as 2/3 = 8/[?] (not [?]/8), making 12 the correct answer, but the confused narrative would mislead students.",
    "12461": "Solution has a sign error in setup: writes 'Zach = Matthew - 200 - 474' but the problem states Zach had 200 ml MORE than Matthew (should be Matthew + 200 - 474). This leads to wrong equations (Matthew - 674 instead of Matthew - 274) and an ultimately wrong computation. Solution is also truncated with '...'. Stored answers (548, 748) are correct but the solution's reasoning is wrong."
