There are 4 shapes on a 5x5 grid. Which shape is closest to the orange 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: orange trapezoid at (0, 4)
Distance from target shape to gray right_triangle at (1, 3): 2
Distance from target shape to purple rectangle at (3, 4): 3
Distance from target shape to red trapezoid at (4, 0): 8
Closest shape is the gray right_triangle at (1, 3) with distance 2</think>
