There are 5 shapes on a 10x10 grid. Which shape is closest to the gray 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: gray rectangle at (9, 4)
Distance from target shape to yellow trapezoid at (0, 6): 11
Distance from target shape to pink rectangle at (1, 3): 9
Distance from target shape to purple square at (9, 2): 2
Distance from target shape to blue trapezoid at (7, 2): 4
Closest shape is the purple square at (9, 2) with distance 2</think>

<answer>(9, 2)</answer>
