There are 4 shapes on a 9x9 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 (4, 2)
Distance from target shape to brown right_triangle at (4, 5): 3
Distance from target shape to gray trapezoid at (2, 1): 3
Distance from target shape to pink rectangle at (0, 7): 9
Closest shape is the brown right_triangle at (4, 5) with distance 3</think>
