There are 4 shapes on a 10x10 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 (0, 3)
Distance from target shape to red square at (1, 6): 4
Distance from target shape to blue trapezoid at (1, 2): 2
Distance from target shape to gray square at (3, 7): 7
Closest shape is the blue trapezoid at (1, 2) with distance 2</think>
