There are 6 shapes on a 9x9 grid. Which shape is closest to the yellow 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: yellow trapezoid at (7, 1)
Distance from target shape to purple trapezoid at (7, 0): 1
Distance from target shape to red square at (2, 6): 10
Distance from target shape to brown trapezoid at (0, 6): 12
Distance from target shape to pink trapezoid at (2, 7): 11
Distance from target shape to green square at (8, 7): 7
Closest shape is the purple trapezoid at (7, 0) with distance 1</think>
