There are 5 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 (4, 3)
Distance from target shape to orange square at (1, 2): 4
Distance from target shape to blue square at (3, 0): 4
Distance from target shape to red square at (2, 4): 3
Distance from target shape to yellow square at (2, 3): 2
Closest shape is the yellow square at (2, 3) with distance 2</think>
