There are 5 shapes on a 3x3 grid. Which shape is closest to the orange rectangle 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 rectangle at (2, 0)
Distance from target shape to yellow right_triangle at (1, 2): 3
Distance from target shape to red square at (0, 2): 4
Distance from target shape to purple rectangle at (2, 1): 1
Distance from target shape to gray trapezoid at (0, 1): 3
Closest shape is the purple rectangle at (2, 1) with distance 1</think>
