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