There are 6 shapes on a 10x10 grid. Which shape is closest to the pink square 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 square at (6, 7)
Distance from target shape to yellow trapezoid at (8, 3): 6
Distance from target shape to orange trapezoid at (0, 1): 12
Distance from target shape to blue square at (5, 5): 3
Distance from target shape to cyan trapezoid at (7, 9): 3
Distance from target shape to green rectangle at (5, 9): 3
Closest shape is the blue square at (5, 5) with distance 3</think>
