There are 6 shapes on a 9x9 grid. Which shape is closest to the brown 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: brown trapezoid at (2, 3)
Distance from target shape to cyan rectangle at (2, 4): 1
Distance from target shape to purple rectangle at (5, 0): 6
Distance from target shape to yellow trapezoid at (3, 0): 4
Distance from target shape to green rectangle at (8, 7): 10
Distance from target shape to gray right_triangle at (3, 1): 3
Closest shape is the cyan rectangle at (2, 4) with distance 1</think>
