There are 4 shapes on a 6x6 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 (2, 0)
Distance from target shape to green trapezoid at (1, 0): 1
Distance from target shape to red right_triangle at (0, 2): 4
Distance from target shape to yellow trapezoid at (1, 5): 6
Closest shape is the green trapezoid at (1, 0) with distance 1</think>
