There are 5 shapes on a 7x7 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 orange square at (4, 1): 3
Distance from target shape to pink trapezoid at (5, 0): 3
Distance from target shape to green square at (3, 0): 1
Distance from target shape to purple right_triangle at (5, 4): 7
Closest shape is the green square at (3, 0) with distance 1</think>
