There are 6 shapes on a 8x8 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 (2, 5)
Distance from target shape to yellow rectangle at (6, 3): 6
Distance from target shape to blue rectangle at (6, 2): 7
Distance from target shape to cyan trapezoid at (5, 4): 4
Distance from target shape to gray trapezoid at (2, 7): 2
Distance from target shape to purple square at (7, 7): 7
Closest shape is the gray trapezoid at (2, 7) with distance 2</think>
