There are 6 shapes on a 6x6 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 (0, 2)
Distance from target shape to pink right_triangle at (3, 5): 6
Distance from target shape to purple right_triangle at (2, 4): 4
Distance from target shape to orange trapezoid at (3, 1): 4
Distance from target shape to red trapezoid at (5, 5): 8
Distance from target shape to blue square at (3, 3): 4
Closest shape is the purple right_triangle at (2, 4) with distance 4</think>
