Read the short paragraph about the London Underground and choose the correct plan of the text.

The London Underground (or the Tube) is the oldest and largest underground network in the world. It's got 11 lines and 287 stations. The first line (between Paddington and Farrington) was opened in 1863.

Only about sixty per cent of the Tube lies under the ground; forty per cent is above. The Tube works from 5:30 am to 1:00 am most days and twenty-four hours per day on public holidays. There are two types of tickets you can use to get on the Tube: paper Travelcards and Oyster smart cards.

Most of the stations have a simple design, but with the help of the "Art on the Underground" project, there are lots of artworks and installations in the stations. Some of them change every month; some are permanent.
