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