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