There are 5 shapes on a 8x8 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 (2, 4)
Distance from target shape to brown rectangle at (0, 0): 6
Distance from target shape to green right_triangle at (3, 5): 2
Distance from target shape to pink square at (4, 4): 2
Distance from target shape to yellow square at (1, 3): 2
Closest shape is the green right_triangle at (3, 5) with distance 2</think>
