There are 4 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 (5, 4)
Distance from target shape to yellow rectangle at (2, 7): 6
Distance from target shape to gray rectangle at (0, 2): 7
Distance from target shape to orange trapezoid at (5, 6): 2
Closest shape is the orange trapezoid at (5, 6) with distance 2</think>
