There are 5 shapes on a 5x5 grid. Which shape is closest to the pink 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: pink trapezoid at (2, 2)
Distance from target shape to cyan right_triangle at (1, 2): 1
Distance from target shape to yellow right_triangle at (3, 0): 3
Distance from target shape to red square at (0, 0): 4
Distance from target shape to purple rectangle at (1, 1): 2
Closest shape is the cyan right_triangle at (1, 2) with distance 1</think>
