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