There are 4 shapes on a 6x6 grid. Which shape is closest to the yellow 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: yellow trapezoid at (2, 2)
Distance from target shape to gray trapezoid at (1, 4): 3
Distance from target shape to purple square at (0, 3): 3
Distance from target shape to blue trapezoid at (5, 2): 3
Closest shape is the gray trapezoid at (1, 4) with distance 3</think>
