There are 5 shapes on a 9x9 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 (1, 3)
Distance from target shape to blue trapezoid at (0, 8): 6
Distance from target shape to orange right_triangle at (8, 4): 8
Distance from target shape to yellow square at (5, 8): 9
Distance from target shape to gray square at (0, 7): 5
Closest shape is the gray square at (0, 7) with distance 5</think>
