    "29740": "Solution defers to printed key: 'Using the printed key, the overlap means total = 11 units'. Should derive 1:11 independently (the initial 1:12 calculation is contradicted by key without proper reasoning).",
    "29757": "Solution is cut off mid-sentence at 'The print'. Additionally, the math correctly yields $72 but the answer key says $180 -- KEY CONFLICT. Solution reaches $72 but the keyed answer is $180 (correct_index=3, option [3]).",
    "29769": "Solution ends mid-sentence: 'the area available for triangle NFG.' -- incomplete, does not state final answer or complete the area calculation.",
    "29785": "Gibberish solution: '3/8 = 3 / 8 = 0.375' is completely unrelated to the question about books on shelves and initial ratio. The question asks for the at-first ratio of Shelf A to Shelf B books; solution must show working with the 1/7 transfer and 3:5 final ratio.",
    "29786": "Solution text is completely mismatched to the question. Question is about Stall A/B burgers and sandwiches, but solution reads 'Side = cube root of the volume = cube root of 125 = 5 m (since 5x5x5=125).' -- belongs to a different question entirely.",
    "29824": "Solution incomplete: computes square side = 7 cm and semicircle arc = 33 cm but does not finish the perimeter calculation. Does not state the final perimeter or sum the remaining straight segments.",
    "29825": "Solution says 'Using the angle properties of the folded trapezium, angle x works out to the value given by the key.' This is not proper reasoning -- it merely trusts the answer key without deriving the angle.",
    "29831": "Solution is jumbled with 'key working:' prefix and unclear angle derivation: 'key working: 180 - 90 = 90, 90 / 2 = 45; then 180 - 45 - 30 - 90 gives angle JKL = 15.' The reasoning is not clearly laid out.",
    "29845": "Solution jumps directly to '1/2 x 21 x 14 = 147 cm^2' without showing how the conditions (PS=2xST, ST:TW:WR=1:3:1, perimeter difference of 56 cm) yield the dimensions 21 and 14. Derivation is missing.",
    "29851": "Solution uses 'Key working:' prefix and the derivation is opaque: '9u - 2u = 7u = 100 + 48 + 48 = 196'. The reasoning is not clearly explained.",
    "29899": "KEY CONFLICT acknowledged in the solution: 'The question asks altogether... the key states u = 21 as the answer.' Mathematics gives 23 bags altogether (21 initial + 2 more), but answer recorded as 21. Solution writer notes the discrepancy but defers to the key.",
    "29917": "Empty solution -- no text at all for a cuboid volume question (faces 30 cm^2 and 24 cm^2, answer 120 cm^3)."
