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