A、To help people start their own small business. B、To provide accommodation for holidaymakers. C、To link providers of spare room

W: So Rob, tell me, do you have a spare room in your house?
M: Absolutely not. We’re full to capacity in our house.
W: And what about a driveway for your car?
M: A driveway? You mean a parking space off the road at my house? Not exactly a driveway, but yes, I do have a parking space.
W: Well, both of these are ways of making money in the "sharing economy".(1-1)In February 2014, Britain’s most expensive parking space went on sale. Do you know how much it is worth? Here are some choices: a)￡80,000, b)￡100,000, and c)￡400,000.
M: Well, it’s just a parking space, isn’t it? So I’m going to go for the lowest value: ￡80,000.
W: ￡80,000, urn, a lot of money.(1-2)But you are completely wrong. It was the most expensive one: ￡400,000.
M: No way! For a parking space!
W: That’s why I say you can use your parking space for some extra money in the " sharing economy". (2)Perhaps the best-known example of a company in the sharing economy is Airbnb—it’s an American web business which allows you to rent out your spare room to holidaymakers. Airbnb says they operate in 34,000 cities and have 800,000 listings of rooms and apartments. In fact, we could say they’re the market-leader in this industry—the main, most successful company.
M: Sounds not bad. What about the sharing parking spaces?
W: One example is JustPark. It’s a British business that lets you rent out your driveway or parking space. (3)So far, around 20,000 people have put their spaces on the site, and around half a million drivers use it.(4)A church near Kings Cross in central London has apparently made over ￡200,000 by renting out space in its yard to travelers!
M: That’s interesting! Maybe I should find more information about it.
W: Yes, you should.
