There are 3 shapes on a 4x4 grid. Which shape is closest to the brown 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: brown trapezoid at (3, 2)
Distance from target shape to cyan trapezoid at (2, 3): 2
Distance from target shape to yellow rectangle at (3, 3): 1
Closest shape is the yellow rectangle at (3, 3) with distance 1</think>

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