There are 5 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 purple right_triangle at (3, 4): 6
Distance from target shape to gray rectangle at (3, 3): 5
Distance from target shape to yellow square at (0, 3): 2
Distance from target shape to red trapezoid at (1, 3): 3
Closest shape is the yellow square at (0, 3) with distance 2</think>
