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, 0)
Distance from target shape to blue right_triangle at (4, 3): 5
Distance from target shape to red trapezoid at (4, 0): 2
Distance from target shape to yellow right_triangle at (2, 4): 4
Distance from target shape to cyan right_triangle at (0, 3): 5
Closest shape is the red trapezoid at (4, 0) with distance 2</think>
