There are 4 shapes on a 5x5 grid. Which shape is closest to the pink 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: pink trapezoid at (1, 0)
Distance from target shape to brown trapezoid at (3, 1): 3
Distance from target shape to purple rectangle at (3, 3): 5
Distance from target shape to orange right_triangle at (4, 4): 7
Closest shape is the brown trapezoid at (3, 1) with distance 3</think>
