There are 4 shapes on a 5x5 grid. Which shape is closest to the orange 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: orange square at (3, 2)
Distance from target shape to pink trapezoid at (2, 1): 2
Distance from target shape to purple trapezoid at (2, 3): 2
Distance from target shape to green trapezoid at (0, 4): 5
Closest shape is the pink trapezoid at (2, 1) with distance 2</think>
