There are 5 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 (3, 0)
Distance from target shape to red rectangle at (0, 2): 5
Distance from target shape to purple trapezoid at (1, 5): 7
Distance from target shape to orange trapezoid at (4, 1): 2
Distance from target shape to cyan right_triangle at (5, 4): 6
Closest shape is the orange trapezoid at (4, 1) with distance 2</think>
