Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions.

Garbage collectors in the Turkish capital Ankara are recycling the books they find in the trash. They have created a mobile library. The library is full of books that people have thrown away. There are now over 9,000 books on the library's shelves. The library is inside a truck that tours schools in the suburbs of Ankara. The garbage collectors hope to create a greater passion for reading books in children, especially in the age of mobile phones and tablets. Many schools do not have a reading room or their own library.

The library has got a lot of attention in Turkey. There is now a campaign for it to grow. People from all over Turkey are sending their unwanted or old books to the garbage collectors. The director of the library said: "The interest is growing. Each day we have guests coming here to borrow books or have a quiet time to read." A worker at the mobile library said: "We have books here for children aged from six to ten, but also books for older children. We hope that it will amuse them and arouse a passion for books." Turkey currently has just one public library for every 70,000 people, compared to one for every 6,200 people in the European Union.
