There are 4 shapes on a 10x10 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 (4, 7)
Distance from target shape to purple trapezoid at (8, 5): 6
Distance from target shape to gray square at (5, 2): 6
Distance from target shape to blue square at (2, 1): 8
Closest shape is the purple trapezoid at (8, 5) with distance 6</think>

<answer>(8, 5)</answer>
