There are 5 shapes on a 4x4 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, 0)
Distance from target shape to yellow rectangle at (2, 1): 1
Distance from target shape to gray rectangle at (0, 0): 2
Distance from target shape to green trapezoid at (0, 2): 4
Distance from target shape to red trapezoid at (1, 2): 3
Closest shape is the yellow rectangle at (2, 1) with distance 1</think>
