There are 6 shapes on a 5x5 grid. Which shape is closest to the pink trapezoid 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 trapezoid at (2, 1)
Distance from target shape to green square at (0, 1): 2
Distance from target shape to yellow trapezoid at (1, 0): 2
Distance from target shape to red rectangle at (1, 2): 2
Distance from target shape to purple rectangle at (4, 3): 4
Distance from target shape to brown trapezoid at (4, 0): 3
Closest shape is the green square at (0, 1) with distance 2</think>
