There are 6 shapes on a 5x5 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, 2)
Distance from target shape to red rectangle at (3, 1): 4
Distance from target shape to orange trapezoid at (2, 1): 3
Distance from target shape to cyan trapezoid at (2, 3): 3
Distance from target shape to yellow square at (3, 4): 5
Distance from target shape to green rectangle at (4, 3): 5
Closest shape is the orange trapezoid at (2, 1) with distance 3</think>
