There are 4 shapes on a 9x9 grid. Which shape is closest to the red 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: red trapezoid at (4, 3)
Distance from target shape to orange square at (8, 3): 4
Distance from target shape to pink trapezoid at (3, 6): 4
Distance from target shape to gray trapezoid at (1, 6): 6
Closest shape is the orange square at (8, 3) with distance 4</think>

<answer>(8, 3)</answer>
