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 (1, 1)
Distance from target shape to yellow rectangle at (1, 3): 2
Distance from target shape to red square at (3, 2): 3
Distance from target shape to blue right_triangle at (0, 0): 2
Distance from target shape to cyan trapezoid at (0, 1): 1
Closest shape is the cyan trapezoid at (0, 1) with distance 1</think>
