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