There are 5 shapes on a 8x8 grid. Which shape is closest to the cyan trapezoid 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 trapezoid at (4, 7)
Distance from target shape to pink trapezoid at (3, 1): 7
Distance from target shape to purple right_triangle at (2, 4): 5
Distance from target shape to blue right_triangle at (2, 0): 9
Distance from target shape to orange trapezoid at (4, 4): 3
Closest shape is the orange trapezoid at (4, 4) with distance 3</think>
