There are 6 shapes on a 6x6 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 (1, 0)
Distance from target shape to cyan rectangle at (2, 5): 6
Distance from target shape to brown right_triangle at (5, 1): 5
Distance from target shape to yellow trapezoid at (0, 2): 3
Distance from target shape to purple square at (0, 3): 4
Distance from target shape to green trapezoid at (4, 5): 8
Closest shape is the yellow trapezoid at (0, 2) with distance 3</think>
