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