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