There are 6 shapes on a 8x8 grid. Which shape is closest to the orange 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: orange trapezoid at (3, 0)
Distance from target shape to gray trapezoid at (6, 3): 6
Distance from target shape to purple rectangle at (0, 1): 4
Distance from target shape to red right_triangle at (5, 5): 7
Distance from target shape to yellow square at (7, 7): 11
Distance from target shape to green trapezoid at (0, 6): 9
Closest shape is the purple rectangle at (0, 1) with distance 4</think>
