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