There are 6 shapes on a 5x5 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, 3)
Distance from target shape to green right_triangle at (3, 2): 4
Distance from target shape to brown right_triangle at (3, 1): 5
Distance from target shape to blue right_triangle at (4, 2): 5
Distance from target shape to cyan rectangle at (3, 0): 6
Distance from target shape to pink right_triangle at (1, 2): 2
Closest shape is the pink right_triangle at (1, 2) with distance 2</think>
