There are 4 shapes on a 8x8 grid. Which shape is closest to the yellow 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: yellow rectangle at (0, 2)
Distance from target shape to pink right_triangle at (5, 7): 10
Distance from target shape to red square at (6, 0): 8
Distance from target shape to brown trapezoid at (0, 6): 4
Closest shape is the brown trapezoid at (0, 6) with distance 4</think>
