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 gray square at (0, 0): 2
Distance from target shape to cyan square at (1, 3): 2
Distance from target shape to blue rectangle at (3, 0): 3
Distance from target shape to brown square at (4, 3): 5
Closest shape is the gray square at (0, 0) with distance 2</think>
