There are 6 shapes on a 8x8 grid. Which shape is closest to the yellow 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: yellow trapezoid at (2, 3)
Distance from target shape to orange rectangle at (0, 2): 3
Distance from target shape to brown right_triangle at (3, 3): 1
Distance from target shape to purple square at (1, 6): 4
Distance from target shape to cyan square at (3, 2): 2
Distance from target shape to gray rectangle at (7, 2): 6
Closest shape is the brown right_triangle at (3, 3) with distance 1</think>
