There are 4 shapes on a 9x9 grid. Which shape is closest to the gray trapezoid 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 trapezoid at (3, 6)
Distance from target shape to orange trapezoid at (3, 5): 1
Distance from target shape to red trapezoid at (8, 6): 5
Distance from target shape to cyan square at (7, 0): 10
Closest shape is the orange trapezoid at (3, 5) with distance 1</think>
