There are 6 shapes on a 5x5 grid. Which shape is closest to the cyan rectangle 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 rectangle at (0, 1)
Distance from target shape to red trapezoid at (3, 4): 6
Distance from target shape to orange rectangle at (1, 3): 3
Distance from target shape to purple square at (4, 3): 6
Distance from target shape to gray square at (2, 3): 4
Distance from target shape to pink rectangle at (0, 4): 3
Closest shape is the orange rectangle at (1, 3) with distance 3</think>
