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