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 (5, 6)
Distance from target shape to yellow trapezoid at (1, 1): 9
Distance from target shape to purple right_triangle at (1, 0): 10
Distance from target shape to orange rectangle at (4, 4): 3
Distance from target shape to pink square at (1, 2): 8
Closest shape is the orange rectangle at (4, 4) with distance 3</think>
