There are 5 shapes on a 5x5 grid. Which shape is closest to the orange 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: orange trapezoid at (1, 4)
Distance from target shape to red trapezoid at (3, 3): 3
Distance from target shape to pink right_triangle at (4, 0): 7
Distance from target shape to brown rectangle at (4, 3): 4
Distance from target shape to green trapezoid at (3, 4): 2
Closest shape is the green trapezoid at (3, 4) with distance 2</think>
