Q: 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.
A: How many books are there in the British Library?
Rationale: In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.
Q: Article: MERS, also known as Middle East Respiratory Syndrome, has made its way to the US. The second patient was in Orlando, Florida while the first reported case was in Indiana. Tom Frieden, director of the Centers for Disease Control and Prevention, said the disease has mainly been transmitted by close personal contact, such as directly caring for a very ill person. The virus is formally called MERS-CoV because it's part of the corona virus family that includes the common cold and severe SARS. SARS was ly easy to stop a decade ago, because it was being transmitted by caged animals in Chinese markets. MERS-CoV was first identified in people in 2012, but has been spreading rapidly since March, 2015. The vast majority of those cases occurred in Saudi Arabia. The patient in Orlando felt ill on the first flight but not ill enough to notify a doctor. Early on May 9, he apparently became concerned that he was still feeling ill, and he went to the emergency room at Dr. P. Phillips Hospital. He identified himself as recently having been in Saudi Arabia, so he was quickly isolated to avoid infecting other patients. Wayne Marasco, an expert at the Dana-Farber Cancer Institute and Harvard Medical School, said his biggest concern about MERS-CoV is how little we know about it. It's still not clear, in some instances, where the virus comes from, how it is transmitted or who is most subject.
Answer: By close personal contact.
A:
According to Tom Frieden, how is a person mainly infected by MERS?
