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

<answer>(6, 5)</answer>
