There are 4 shapes on a 10x10 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 (9, 8)
Distance from target shape to orange right_triangle at (4, 2): 11
Distance from target shape to brown right_triangle at (9, 7): 1
Distance from target shape to red trapezoid at (1, 0): 16
Closest shape is the brown right_triangle at (9, 7) with distance 1</think>

<answer>(9, 7)</answer>
