There are 5 shapes on a 9x9 grid. Which shape is closest to the yellow square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: yellow square at (7, 1)
Distance from target shape to cyan right_triangle at (3, 5): 8
Distance from target shape to brown trapezoid at (7, 2): 1
Distance from target shape to pink square at (6, 1): 1
Distance from target shape to gray square at (6, 8): 8
Closest shape is the brown trapezoid at (7, 2) with distance 1</think>
