There are 6 shapes on a 7x7 grid. Which shape is closest to the pink square 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 square at (2, 5)
Distance from target shape to yellow right_triangle at (4, 3): 4
Distance from target shape to green rectangle at (0, 5): 2
Distance from target shape to orange square at (6, 3): 6
Distance from target shape to red rectangle at (3, 5): 1
Distance from target shape to purple right_triangle at (4, 4): 3
Closest shape is the red rectangle at (3, 5) with distance 1</think>
