There are 6 shapes on a 3x3 grid. Which shape is closest to the yellow rectangle 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 rectangle at (0, 1)
Distance from target shape to pink trapezoid at (0, 2): 1
Distance from target shape to purple right_triangle at (1, 1): 1
Distance from target shape to orange right_triangle at (2, 1): 2
Distance from target shape to red square at (1, 2): 2
Distance from target shape to gray trapezoid at (2, 0): 3
Closest shape is the pink trapezoid at (0, 2) with distance 1</think>
