Attempt Number: 2
Error Message: Action not unique compared to other actions chosen from this state before. Choose a new action

Action Reasoning:
To move closer to the goal, I will move car_2 from behind car_3 on curb_2 to the empty curb_1. This action will help in clearing curb_2, allowing car_3 to become clear, and positions car_2 correctly in curb_1 as per the goal state.

New State Description:
Curb_0 has car_0 parked, clear. Curb_1 now has car_2 parked, clear. Curb_2 has car_3 parked, clear. Curb_3 has car_1 parked, clear. All cars are now clear and parked in their correct positions.

Action Chosen:
(move-car-to-curb car_2 car_3 curb_1)
