There are 6 shapes on a 9x9 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 (1, 3)
Distance from target shape to purple square at (3, 5): 4
Distance from target shape to orange square at (7, 2): 7
Distance from target shape to cyan trapezoid at (1, 1): 2
Distance from target shape to green square at (8, 2): 8
Distance from target shape to gray square at (1, 2): 1
Closest shape is the gray square at (1, 2) with distance 1</think>
