There are 4 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, 0)
Distance from target shape to orange square at (0, 6): 12
Distance from target shape to cyan trapezoid at (4, 1): 3
Distance from target shape to green square at (2, 5): 9
Closest shape is the cyan trapezoid at (4, 1) with distance 3</think>
