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 (3, 3)
Distance from target shape to blue right_triangle at (2, 0): 4
Distance from target shape to green rectangle at (0, 2): 4
Distance from target shape to cyan rectangle at (0, 3): 3
Distance from target shape to orange trapezoid at (3, 4): 1
Distance from target shape to brown right_triangle at (2, 3): 1
Closest shape is the orange trapezoid at (3, 4) with distance 1</think>
