There are 4 shapes on a 9x9 grid. Which shape is closest to the yellow square 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 square at (6, 5)
Distance from target shape to cyan trapezoid at (0, 2): 9
Distance from target shape to pink trapezoid at (8, 6): 3
Distance from target shape to brown rectangle at (5, 3): 3
Closest shape is the pink trapezoid at (8, 6) with distance 3</think>

<answer>(8, 6)</answer>
