There are 6 shapes on a 3x3 grid. Which shape is closest to the orange 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: orange square at (0, 1)
Distance from target shape to brown trapezoid at (1, 1): 1
Distance from target shape to gray square at (0, 2): 1
Distance from target shape to purple square at (2, 0): 3
Distance from target shape to green right_triangle at (2, 2): 3
Distance from target shape to pink square at (0, 0): 1
