There are 6 shapes on a 6x6 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 (2, 0)
Distance from target shape to brown right_triangle at (0, 2): 4
Distance from target shape to orange right_triangle at (4, 0): 2
Distance from target shape to green rectangle at (0, 3): 5
Distance from target shape to yellow trapezoid at (2, 2): 2
Distance from target shape to blue rectangle at (0, 1): 3
Closest shape is the orange right_triangle at (4, 0) with distance 2</think>
