There are 5 shapes on a 6x6 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 (4, 4)
Distance from target shape to purple rectangle at (2, 5): 3
Distance from target shape to blue rectangle at (5, 5): 2
Distance from target shape to gray right_triangle at (0, 4): 4
Distance from target shape to red right_triangle at (4, 0): 4
Closest shape is the blue rectangle at (5, 5) with distance 2</think>
