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 (3, 1)
Distance from target shape to brown square at (0, 2): 4
Distance from target shape to red trapezoid at (3, 3): 2
Distance from target shape to green trapezoid at (2, 0): 2
Distance from target shape to pink square at (0, 0): 4
Closest shape is the red trapezoid at (3, 3) with distance 2</think>
