There are 5 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 (4, 5)
Distance from target shape to purple trapezoid at (6, 6): 3
Distance from target shape to brown trapezoid at (4, 3): 2
Distance from target shape to green square at (0, 3): 6
Distance from target shape to pink rectangle at (0, 0): 9
Closest shape is the brown trapezoid at (4, 3) with distance 2</think>
