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

<answer>(3, 3)</answer>
