There are 4 shapes on a 10x10 grid. Which shape is closest to the orange 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: orange trapezoid at (0, 4)
Distance from target shape to red right_triangle at (9, 8): 13
Distance from target shape to yellow square at (5, 6): 7
Distance from target shape to green trapezoid at (5, 1): 8
Closest shape is the yellow square at (5, 6) with distance 7</think>

<answer>(5, 6)</answer>
