There are 4 shapes on a 7x7 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 (2, 5)
Distance from target shape to green square at (5, 2): 6
Distance from target shape to purple rectangle at (4, 4): 3
Distance from target shape to red rectangle at (0, 3): 4
Closest shape is the purple rectangle at (4, 4) with distance 3</think>

<answer>(4, 4)</answer>
