There are 6 shapes on a 5x5 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 (3, 4)
Distance from target shape to purple trapezoid at (3, 2): 2
Distance from target shape to red right_triangle at (2, 3): 2
Distance from target shape to brown trapezoid at (3, 0): 4
Distance from target shape to gray right_triangle at (4, 1): 4
Distance from target shape to blue trapezoid at (0, 1): 6
Closest shape is the purple trapezoid at (3, 2) with distance 2</think>
