There are 6 shapes on a 6x6 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 (2, 0)
Distance from target shape to blue rectangle at (2, 4): 4
Distance from target shape to cyan square at (4, 4): 6
Distance from target shape to green trapezoid at (0, 1): 3
Distance from target shape to orange trapezoid at (5, 3): 6
Distance from target shape to purple right_triangle at (4, 3): 5
Closest shape is the green trapezoid at (0, 1) with distance 3</think>
