There are 4 shapes on a 10x10 grid. Which shape is closest to the pink 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: pink trapezoid at (5, 1)
Distance from target shape to green trapezoid at (2, 2): 4
Distance from target shape to red rectangle at (7, 9): 10
Distance from target shape to orange right_triangle at (2, 9): 11
Closest shape is the green trapezoid at (2, 2) with distance 4</think>
