There are 6 shapes on a 3x3 grid. Which shape is closest to the pink 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: pink rectangle at (0, 1)
Distance from target shape to purple trapezoid at (2, 0): 3
Distance from target shape to orange rectangle at (0, 0): 1
Distance from target shape to blue rectangle at (1, 0): 2
Distance from target shape to cyan trapezoid at (0, 2): 1
Distance from target shape to yellow rectangle at (2, 2): 3
Closest shape is the orange rectangle at (0, 0) with distance 1</think>
