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 (2, 7)
Distance from target shape to cyan trapezoid at (4, 5): 4
Distance from target shape to green rectangle at (6, 3): 8
Distance from target shape to pink square at (3, 2): 6
Closest shape is the cyan trapezoid at (4, 5) with distance 4</think>
