A、Because so many people are on vacation now. B、Because there is more supply than demand. C、Because the car eats up gas quickly.

W: Hi. How can I help you?
M: Yeah. I’d like to rent a mid-size car for three days.
W: Okay. Let me check to see if we have one available. Hmm. It doesn’t look like we do. We have a couple of economy, compact, and full-size cars available, or a nice minivan.
M: What is the main difference between these cars?
W: The main difference is size. How many people are with you?
M: Just me and my son.
W: Well, the economy car would work. We have one right out front.
M: Where? That one? [6]It looks more like a shoebox to me. I’m really tall and trying to squeeze into that thing... I don’t think so.
W: Well, if you need more room or comfort, I recommend the full-size car.
M: And what is the daily rate for that anyway?
W: Let’s see here... It’ll come to $57.95 a day.
M: Wow, a little expensive. But what’s the cost for mileage?
W: All of our cars have unlimited miles, but of course, that doesn’t include gas.
M: Yeah, right. I bet that car probably eats up gas, and [7]now that we’re in the middle of the vacation season, gas stations are gouging consumers with astronomical prices.
W: Well, as they say, it comes down to the law of supply and demand.
M: Anyway, can you install a car seat in one of those cars? I have a 3-year-old son with me.
W: Sure, and that’ll only be $1 extra per day.
M: I’ll go with the full-size car.
W: Okay. Would you like to purchase our daily car protection plan?
M: What’s that exactly?
W: Well, [8]the car protection plan is a complete insurance package covering damage to the vehicle, injury or loss of life to you or your passengers.
M: Oh... Well...
W: However, it won’t cover loss of property due to theft. Too much crime in the area anyway.
M: How much is the protection plan?
W: [9]It is only $17.95 per day. And the nicest thing about this coverage is that you can rent the car without the worry and hassle of making a complicated claim in case you do have a problem.
M: But wouldn’t my own car insurance cover those problems?
W: It might, but each insurance policy is different. With our car protection plan, however, you deal directly with us in case there is a problem and we handle everything quickly, and you don’t have to contact your own insurance company.
M: Okay. I’ll take it.
W: Let me just confirm this. [10]A full-size car with a car seat for three days, plus the car protection package. Is that right?
M: Yes. That’s it.
