There are 5 shapes on a 10x10 grid. Which shape is closest to the pink 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: pink trapezoid at (8, 7)
Distance from target shape to orange trapezoid at (0, 8): 9
Distance from target shape to blue trapezoid at (2, 9): 8
Distance from target shape to cyan rectangle at (7, 9): 3
Distance from target shape to purple rectangle at (7, 2): 6
Closest shape is the cyan rectangle at (7, 9) with distance 3</think>

<answer>(7, 9)</answer>
