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