There are 6 shapes on a 8x8 grid. Which shape is closest to the yellow 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: yellow trapezoid at (7, 1)
Distance from target shape to purple rectangle at (0, 7): 13
Distance from target shape to red trapezoid at (1, 5): 10
Distance from target shape to cyan trapezoid at (6, 7): 7
Distance from target shape to pink square at (7, 3): 2
Distance from target shape to brown square at (2, 6): 10
Closest shape is the pink square at (7, 3) with distance 2</think>
