There are 5 shapes on a 9x9 grid. Which shape is closest to the pink rectangle 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 rectangle at (0, 5)
Distance from target shape to orange square at (1, 3): 3
Distance from target shape to red right_triangle at (3, 8): 6
Distance from target shape to brown trapezoid at (0, 4): 1
Distance from target shape to green square at (6, 1): 10
Closest shape is the brown trapezoid at (0, 4) with distance 1</think>
