There are 5 shapes on a 6x6 grid. Which shape is closest to the red 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: red trapezoid at (3, 3)
Distance from target shape to cyan trapezoid at (5, 2): 3
Distance from target shape to blue trapezoid at (1, 2): 3
Distance from target shape to orange rectangle at (4, 4): 2
Distance from target shape to purple square at (0, 1): 5
Closest shape is the orange rectangle at (4, 4) with distance 2</think>
