There are 4 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 (0, 4)
Distance from target shape to purple square at (0, 1): 3
Distance from target shape to red trapezoid at (1, 4): 1
Distance from target shape to yellow trapezoid at (1, 3): 2
Closest shape is the red trapezoid at (1, 4) with distance 1</think>
