Which of the following details is CORRECT about the woman?

M: How was your vacation last week?
W: It’s wonderful. I went to Hawaii. It’s the first time when I had rented a car for the trip.
M: It’s more convenient to drive a car to travel along great scenes. Which type of vehicle did you choose?
W: I rented an SUV because I was planning on driving in some national parks.
M: Last time I also contacted a car rental agency. How much did it cost?
W: (4)I was able to get the weekly rate of $55 a day, not including tax. However, the SUV came with unlimited miles, so I didn’t have to pay extra for the number of miles I drove.
M: Did you purchase additional insurance to protect you and the car in case of an accident?
W: The manager recommended that I buy the additional insurance that would cover the vehicle in case of an accident, (5) but I told him that my own insurance covered rental cars.
M: So you signed your agreement and started your vocation without purchasing any insurance?
W: Yeah, but I returned the SUV a week later with a problem. There were scratches on it. I swear that it wasn’t my fault.
M: Well, (6)before you left, you should do a visual inspection of the cars to see if it has any scratches on it so you wouldn’t be liable for previous damage to the car.
W: You’re right, it really taught me a lesson.
