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, 0)
Distance from target shape to brown right_triangle at (1, 0): 4
Distance from target shape to red right_triangle at (1, 2): 6
Distance from target shape to green trapezoid at (1, 1): 5
Distance from target shape to gray trapezoid at (4, 0): 1
Closest shape is the gray trapezoid at (4, 0) with distance 1</think>
