There are 6 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, 0)
Distance from target shape to purple right_triangle at (5, 5): 9
Distance from target shape to gray square at (5, 1): 5
Distance from target shape to yellow trapezoid at (4, 1): 4
Distance from target shape to cyan rectangle at (7, 2): 8
Distance from target shape to blue square at (6, 6): 11
Closest shape is the yellow trapezoid at (4, 1) with distance 4</think>
