Given the task definition, example input & output, solve the new input case.
In this task, you're given an article and an answer. Your task is to generate the question for the answer based on the given article.
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.
Output: How many books are there in the British Library?
In the Article, 10,000,000 is mentioned for the number of books available in the British Library, so this is a good question.

New input case for you: Article: While many modern forms of communication like phone calls, e-mail, and letters, are extremely convenient. In my opinion, nothing beats speaking to another person face to face. The first and most obvious advantage that a face communication has over a letter and e-mail is that there is the ability to interactively converse. If the sender of a letter or an email does not write clearly, then much time must be spent to clear up the misunderstanding. In a face-to-face conversation, misunderstandings are easily dealt with because of the interactive nature of it. I would still argue that the face-to-face conversation is better because you can see the other person. Not all communication is verbal ; the meaning of much of what we say depends on our body language and the tone of voice. Joking and irony are particularly difficult to express and enjoy without seeing the expression on someone's face, or watching the movements of their body. Finally, if the goal of communication is to maintain or deepen the relationship with someone, the face-to-face communication offers the choice of communication by touch even if we could communicate by the video. Trust and respect between business partners can be established with a firm handshake. No amount of body language can convey the excitement of a high five between friends, and no number of words can communicate the comforting embrace of a loved one. Touch is the first basic method of our human relationships, before spoken language, and it is only available when people communicate face to face.
Answer: Comparison of different communication forms
