U = I2*R2 = 5*6 = 30 В;
I1 = U/R1 = 30/10 = 3 А;
I3 = I - I1 - I2 = 15 - 5 - 3 = 7 А;
R3 = U/I3 = 30/7 = 4,3 Ом

Dickens World
A theme park that celebrates the life and writings of Charles Dickens has opened in Britain. It`s built on old docks just east of London where Dickens lived for a time as a child.
One of Britain`s greatest writers, Charles Dickens is associated with Victorian London and in particular the misery and poverty (нищета и бедность) of the city. Now Dickens World is opening on an industrial estate in the town of Chatham in Kent where the writer grew up. A theme park is dedicated, so it says, to giving a flavor of life (вкус жизни) in Dickens`s England.
The central boat ride takes visitors through an interactive stage set of picturesque slums (трущобы) and their smells. It provoked a familiar debate of entertainment versus education. The critics say the real Dickens experience is in the books – and trips down fake Victorian sewers (канализация) won`t get people reading. The organisers reply that the writer was a great popular entertainer and could like the idea of such a theme park.
But it is of course a business proposition, investing 120 million dollars, and predicting 300.000 visitors a year. The organisers believe that the name of Dickens and theme park versions of misery and poverty will attract a lot of people to the new park.
1. They built the new theme park called Dickens World in an old park in London.
2. Charles Dickens spent his childhood in Kent not far from London.
3. Dickens described the town of Chatham in three of his novels.
4. Misery and poverty were often the subjects of Dickens`s novels.
5. In the new theme park you can not only see, but also listen and smell the town in the times of Dickens.
6. The main ride of the park is a roller coaster.
7. There is a discussion between Dickens`s readers and the theme park visitors.
8. All visitors of Dickens World will get interested in reading his books.
9. 300.000 people visited Dickens World last year.
10. The new theme park is going to be popular.-
