There are 6 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 (0, 2)
Distance from target shape to yellow square at (1, 0): 3
Distance from target shape to pink trapezoid at (0, 0): 2
Distance from target shape to gray square at (1, 2): 1
Distance from target shape to purple trapezoid at (3, 3): 4
Distance from target shape to brown right_triangle at (1, 1): 2
Closest shape is the gray square at (1, 2) with distance 1</think>
