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