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 (0, 0)
Distance from target shape to gray square at (5, 4): 9
Distance from target shape to red trapezoid at (1, 2): 3
Distance from target shape to yellow rectangle at (4, 2): 6
Distance from target shape to pink square at (2, 4): 6
Closest shape is the red trapezoid at (1, 2) with distance 3</think>
