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