There are 6 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 rectangle at (2, 2): 5
Distance from target shape to green square at (0, 6): 1
Distance from target shape to yellow square at (8, 0): 13
Distance from target shape to brown square at (6, 5): 6
Distance from target shape to purple trapezoid at (5, 5): 5
Closest shape is the green square at (0, 6) with distance 1</think>
