There are 5 shapes on a 4x4 grid. Which shape is closest to the red rectangle in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: red rectangle at (2, 2)
Distance from target shape to purple rectangle at (0, 0): 4
Distance from target shape to cyan rectangle at (0, 3): 3
Distance from target shape to orange trapezoid at (1, 1): 2
Distance from target shape to yellow square at (3, 1): 2
Closest shape is the orange trapezoid at (1, 1) with distance 2</think>
