There are 5 shapes on a 4x4 grid. Which shape is closest to the orange square 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 square at (1, 0)
Distance from target shape to blue trapezoid at (2, 0): 1
Distance from target shape to pink right_triangle at (0, 2): 3
Distance from target shape to green right_triangle at (3, 0): 2
Distance from target shape to gray trapezoid at (3, 2): 4
Closest shape is the blue trapezoid at (2, 0) with distance 1</think>
