There are 5 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 (5, 1)
Distance from target shape to yellow trapezoid at (2, 4): 6
Distance from target shape to brown trapezoid at (4, 0): 2
Distance from target shape to green rectangle at (5, 5): 4
Distance from target shape to pink square at (4, 3): 3
Closest shape is the brown trapezoid at (4, 0) with distance 2</think>
