There are 4 shapes on a 3x3 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, 2)
Distance from target shape to cyan rectangle at (2, 0): 2
Distance from target shape to blue rectangle at (1, 2): 1
Distance from target shape to red right_triangle at (0, 0): 4
Closest shape is the blue rectangle at (1, 2) with distance 1</think>
