There are 5 shapes on a 8x8 grid. Which shape is closest to the pink 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: pink rectangle at (1, 6)
Distance from target shape to purple rectangle at (3, 0): 8
Distance from target shape to orange trapezoid at (2, 7): 2
Distance from target shape to blue trapezoid at (0, 1): 6
Distance from target shape to cyan trapezoid at (0, 3): 4
Closest shape is the orange trapezoid at (2, 7) with distance 2</think>
