There are 4 shapes on a 9x9 grid. Which shape is closest to the gray 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: gray square at (3, 4)
Distance from target shape to blue square at (5, 6): 4
Distance from target shape to orange rectangle at (2, 2): 3
Distance from target shape to red trapezoid at (3, 7): 3
Closest shape is the orange rectangle at (2, 2) with distance 3</think>
