There are 6 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 (4, 1)
Distance from target shape to red right_triangle at (4, 0): 1
Distance from target shape to gray rectangle at (4, 2): 1
Distance from target shape to green trapezoid at (0, 0): 5
Distance from target shape to purple rectangle at (1, 0): 4
Distance from target shape to cyan rectangle at (1, 3): 5
Closest shape is the red right_triangle at (4, 0) with distance 1</think>
