There are 5 shapes on a 8x8 grid. Which shape is closest to the gray 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: gray trapezoid at (6, 2)
Distance from target shape to red trapezoid at (2, 6): 8
Distance from target shape to purple trapezoid at (0, 2): 6
Distance from target shape to green rectangle at (0, 5): 9
Distance from target shape to orange trapezoid at (2, 0): 6
Closest shape is the purple trapezoid at (0, 2) with distance 6</think>
