There are 3 shapes on a 8x8 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 (0, 5)
Distance from target shape to orange rectangle at (7, 0): 12
Distance from target shape to red trapezoid at (7, 2): 10
Closest shape is the red trapezoid at (7, 2) with distance 10</think>
