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 (1, 0)
Distance from target shape to purple right_triangle at (4, 6): 9
Distance from target shape to green rectangle at (5, 4): 8
Distance from target shape to orange rectangle at (6, 0): 5
Distance from target shape to yellow rectangle at (2, 5): 6
Closest shape is the orange rectangle at (6, 0) with distance 5</think>
