There are 4 shapes on a 4x4 grid. Which shape is closest to the orange 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: orange trapezoid at (0, 3)
Distance from target shape to cyan rectangle at (3, 0): 6
Distance from target shape to brown right_triangle at (1, 1): 3
Distance from target shape to green rectangle at (1, 2): 2
Closest shape is the green rectangle at (1, 2) with distance 2</think>
