There are 3 shapes on a 8x8 grid. Which shape is closest to the cyan trapezoid in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: cyan trapezoid at (5, 5)
Distance from target shape to orange right_triangle at (5, 7): 2
Distance from target shape to brown square at (4, 6): 2
Closest shape is the orange right_triangle at (5, 7) with distance 2</think>
