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

<answer>(3, 3)</answer>
