There are 4 shapes on a 6x6 grid. Which shape is closest to the blue 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: blue trapezoid at (0, 2)
Distance from target shape to purple rectangle at (5, 5): 8
Distance from target shape to gray trapezoid at (1, 0): 3
Distance from target shape to pink square at (1, 4): 3
Closest shape is the gray trapezoid at (1, 0) with distance 3</think>
