There are 6 shapes on a 6x6 grid. Which shape is closest to the yellow square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: yellow square at (0, 2)
Distance from target shape to red trapezoid at (5, 3): 6
Distance from target shape to pink right_triangle at (2, 5): 5
Distance from target shape to orange right_triangle at (5, 2): 5
Distance from target shape to green trapezoid at (3, 0): 5
Distance from target shape to gray trapezoid at (5, 1): 6
Closest shape is the pink right_triangle at (2, 5) with distance 5</think>
