There are 6 shapes on a 9x9 grid. Which shape is closest to the pink 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: pink trapezoid at (6, 2)
Distance from target shape to blue rectangle at (2, 5): 7
Distance from target shape to purple trapezoid at (6, 3): 1
Distance from target shape to red square at (0, 3): 7
Distance from target shape to orange square at (0, 8): 12
Distance from target shape to brown trapezoid at (6, 0): 2
Closest shape is the purple trapezoid at (6, 3) with distance 1</think>
