There are 6 shapes on a 7x7 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 (5, 5)
Distance from target shape to brown right_triangle at (6, 1): 5
Distance from target shape to yellow trapezoid at (0, 6): 6
Distance from target shape to pink trapezoid at (3, 3): 4
Distance from target shape to red right_triangle at (1, 1): 8
Distance from target shape to orange right_triangle at (5, 0): 5
Closest shape is the pink trapezoid at (3, 3) with distance 4</think>
