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 (1, 2)
Distance from target shape to yellow square at (0, 4): 3
Distance from target shape to brown square at (1, 4): 2
Distance from target shape to green square at (3, 2): 2
Distance from target shape to purple trapezoid at (3, 1): 3
Distance from target shape to blue rectangle at (0, 1): 2
Closest shape is the brown square at (1, 4) with distance 2</think>
