There are 5 shapes on a 10x10 grid. Which shape is closest to the orange square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: orange square at (7, 0)
Distance from target shape to green trapezoid at (3, 5): 9
Distance from target shape to brown trapezoid at (6, 5): 6
Distance from target shape to purple square at (1, 9): 15
Distance from target shape to red right_triangle at (0, 7): 14
Closest shape is the brown trapezoid at (6, 5) with distance 6</think>
