There are 5 shapes on a 10x10 grid. Which shape is closest to the cyan 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: cyan square at (9, 5)
Distance from target shape to pink rectangle at (6, 9): 7
Distance from target shape to green trapezoid at (4, 4): 6
Distance from target shape to brown trapezoid at (2, 4): 8
Distance from target shape to blue square at (2, 0): 12
Closest shape is the green trapezoid at (4, 4) with distance 6</think>
