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