There are 4 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 (0, 0)
Distance from target shape to yellow rectangle at (2, 7): 9
Distance from target shape to orange trapezoid at (0, 3): 3
Distance from target shape to pink trapezoid at (1, 6): 7
Closest shape is the orange trapezoid at (0, 3) with distance 3</think>
