There are 6 shapes on a 3x3 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 purple square at (0, 0): 1
Distance from target shape to brown right_triangle at (2, 0): 1
Distance from target shape to orange square at (1, 2): 2
Distance from target shape to red trapezoid at (2, 2): 3
Distance from target shape to cyan square at (2, 1): 2
Closest shape is the purple square at (0, 0) with distance 1</think>
