There are 4 shapes on a 9x9 grid. Which shape is closest to the blue square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: blue square at (3, 5)
Distance from target shape to cyan trapezoid at (4, 7): 3
Distance from target shape to green square at (6, 1): 7
Distance from target shape to orange trapezoid at (7, 0): 9
Closest shape is the cyan trapezoid at (4, 7) with distance 3</think>
