There are 6 shapes on a 3x3 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 (0, 1)
Distance from target shape to blue square at (1, 0): 2
Distance from target shape to brown right_triangle at (0, 2): 1
Distance from target shape to orange trapezoid at (1, 1): 1
Distance from target shape to red rectangle at (0, 0): 1
Distance from target shape to cyan square at (2, 2): 3
Closest shape is the brown right_triangle at (0, 2) with distance 1</think>
