There are 5 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 (1, 1)
Distance from target shape to green trapezoid at (3, 0): 3
Distance from target shape to cyan rectangle at (2, 2): 2
Distance from target shape to red right_triangle at (0, 1): 1
Distance from target shape to brown trapezoid at (4, 2): 4
Closest shape is the red right_triangle at (0, 1) with distance 1</think>
