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