Open-ended - With worked solutions · SET 20 Question 74

AI reconstruction: This is a reconstructed reasoning exercise, not an automatically scored missing-tile question. Test the following proposed method: align the first two figures in a row and apply one fixed rule to the two triangle states at each matching position. A state is absent, white or gray; the rule must be identical at every position and in every row. Using the top row, show what this method would force in the missing cell of the bottom row. Does any displayed choice match? Explain the limit of this test. No rotation or reflection is part of the proposed method.
