There are 4 shapes on a 3x3 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 (1, 2)
Distance from target shape to pink rectangle at (0, 0): 3
Distance from target shape to purple right_triangle at (2, 2): 1
Distance from target shape to blue trapezoid at (2, 0): 3
Closest shape is the purple right_triangle at (2, 2) with distance 1</think>
