There are 6 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, 5)
Distance from target shape to red square at (0, 0): 7
Distance from target shape to pink rectangle at (1, 5): 1
Distance from target shape to yellow right_triangle at (3, 1): 5
Distance from target shape to gray right_triangle at (2, 3): 2
Distance from target shape to green rectangle at (3, 4): 2
Closest shape is the pink rectangle at (1, 5) with distance 1</think>
