There are 4 shapes on a 8x8 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 (2, 2)
Distance from target shape to green trapezoid at (0, 0): 4
Distance from target shape to cyan trapezoid at (5, 5): 6
Distance from target shape to yellow right_triangle at (6, 7): 9
Closest shape is the green trapezoid at (0, 0) with distance 4</think>
