Action Reasoning:
To achieve the goal state, we need to move car_2 to curb_1, which is currently clear. This will free car_1 and make it clear, allowing it to be moved to curb_1 later.

New State Description:
Curb_0: Car_0 parked, clear. Curb_1: Car_2 parked, clear. Curb_2: Car_1 parked, clear. Curb_3: Car_3 parked, clear. Cars: Car_0 clear, car_1 clear, car_2 clear, car_3 clear.
