There are 5 shapes on a 3x3 grid. Which shape is closest to the purple 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: purple trapezoid at (1, 2)
Distance from target shape to orange trapezoid at (1, 0): 2
Distance from target shape to brown trapezoid at (0, 0): 3
Distance from target shape to yellow rectangle at (2, 1): 2
Distance from target shape to pink trapezoid at (2, 0): 3
Closest shape is the orange trapezoid at (1, 0) with distance 2</think>
