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