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, 0)
Distance from target shape to blue square at (1, 1): 2
Distance from target shape to green square at (2, 4): 4
Distance from target shape to red rectangle at (5, 0): 3
Closest shape is the blue square at (1, 1) with distance 2</think>
