There are 4 shapes on a 8x8 grid. Which shape is closest to the cyan trapezoid in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: cyan trapezoid at (6, 5)
Distance from target shape to purple square at (7, 6): 2
Distance from target shape to pink rectangle at (1, 0): 10
Distance from target shape to orange rectangle at (2, 7): 6
Closest shape is the purple square at (7, 6) with distance 2</think>

<answer>(7, 6)</answer>
