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 (1, 5)
Distance from target shape to gray rectangle at (4, 0): 8
Distance from target shape to yellow right_triangle at (3, 3): 4
Distance from target shape to blue rectangle at (4, 3): 5
Distance from target shape to brown trapezoid at (1, 0): 5
Closest shape is the yellow right_triangle at (3, 3) with distance 4</think>
