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

<answer>(6, 4)</answer>
