Teacher: Now, understand the problem? If you are still confused, see the following example:
Article: There are a lot of public libraries in Britain. These libraries have more than one hundred and fifteen million books, not including those libraries of public schools. Public libraries not only lend books, music records but also help children, patients in hospitals and others to get special play readings, film shows and so on. The first public libraries were founded in about the year 1850. Today's public libraries usually have a reading-room, a lending room and a reference room. The greatest and most famous library in Britain is that of the British Library in London. It was founded in 1973 and has over 10, 000, 000 books. It has nearly every magazine, newspaper and book published in Britain and other parts across the world.
Answer: 10,000,000 or less.
Solution: How many books are there in the British Library?
Reason: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

Now, solve this instance: Article: When Chinese student Du Juan brought her American boyfriend home two years ago to use the toilet, her Japanese roommate became so upset that she shouted in English: "I hate you." Du, then 21 and an undergraduate at Bridgewater State College in Massachusetts, was shocked. So was her boyfriend. "Later I realized that she didn't literally mean what she said and that she was not aware of the full meaning of the word 'hate' in English," said Du. "It was more a problem with translation," she added. Cultural differences can cause confusion about what words or even actions mean, an issue that has come to the forefront recently following the arrest of a Chinese doctoral degree student in New Jersey. Zhai Tiantian, who studied at the Stevens Institute of Technology, has been accused of trying to set fire to a campus building and of making threats to a professor who gave him a low mark. No physical _ took place but Zhai reportedly said something along the lines of "at worst, I will risk anything on the line." The professor called the campus police. According to the indictment sheet , Zhai is facing the serious charge of making a terroristic threat. For a few days, Chinese media mistranslated, or misunderstood, the charges and reported that Zhai was being charged with terrorism. Some language experts have speculated that the disagreement between Zhai and the professor can also be chalked up to cultural and linguistic differences. "What Chinese people regard as acceptable speech may be regarded by Americans as threats," said Luo Gang, the Chinese Consulate's Overseas Chinese Affairs consul. "This is an unfortunate incident. Even though Zhai intended no harm, he has done himself a great deal of harm." Du, now 23, said she supports Zhai's actions in fighting to save his academic career, but added he needs to learn more about communication in a foreign language. "Chinese students in a foreign country must prepare more in terms of languages and conversation skills to avoid misunderstandings," she said.
Answer: Her roommate spoke such poor English that she felt angry.
Student:
By saying "It was more a problem with translation", what does Du Juan mean?
