There are 6 shapes on a 10x10 grid. Which shape is closest to the brown 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: brown rectangle at (4, 6)
Distance from target shape to red right_triangle at (8, 5): 5
Distance from target shape to green rectangle at (0, 9): 7
Distance from target shape to yellow right_triangle at (9, 4): 7
Distance from target shape to pink trapezoid at (4, 4): 2
Distance from target shape to gray square at (0, 8): 6
Closest shape is the pink trapezoid at (4, 4) with distance 2</think>
