There are 4 shapes on a 4x4 grid. Which shape is closest to the blue 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: blue trapezoid at (3, 2)
Distance from target shape to cyan square at (1, 0): 4
Distance from target shape to brown trapezoid at (0, 2): 3
Distance from target shape to pink rectangle at (0, 0): 5
Closest shape is the brown trapezoid at (0, 2) with distance 3</think>
