There are 6 shapes on a 4x4 grid. Which shape is closest to the pink rectangle 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 rectangle at (0, 1)
Distance from target shape to green trapezoid at (1, 3): 3
Distance from target shape to cyan square at (2, 3): 4
Distance from target shape to blue trapezoid at (2, 1): 2
Distance from target shape to orange right_triangle at (3, 3): 5
Distance from target shape to gray trapezoid at (0, 2): 1
Closest shape is the gray trapezoid at (0, 2) with distance 1</think>
