There are 3 shapes on a 10x10 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 (9, 5)
Distance from target shape to gray rectangle at (4, 7): 7
Distance from target shape to green trapezoid at (8, 6): 2
Closest shape is the green trapezoid at (8, 6) with distance 2</think>

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