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