There are 5 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 (6, 5)
Distance from target shape to gray square at (5, 0): 6
Distance from target shape to cyan square at (4, 2): 5
Distance from target shape to purple trapezoid at (0, 0): 11
Distance from target shape to green rectangle at (3, 3): 5
Closest shape is the cyan square at (4, 2) with distance 5</think>
