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.
One 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 is here: How many books are there in the British Library?
Explanation: 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: Article: The other day, I noticed a message on a friend's page. It made me very sad. She says she is the one who reaches out to people, but rarely do they reach out to her. So, after communicating with her for a while, I began to challenge my friends. "Contact someone right now. Send messages or call someone who you haven't spoken to for a while, or who you only talk to when they message or call you. Let someone who may feel alone in the world right this moment know that they are not alone. That is my challenge to you. Please do it , and let me know once you have. Either by calling me back, or by sending me a message. Be the change that you want to see in the world. " The response was great. 28people liked my post, another 10 posted that they did, and I got about a dozen messages telling me that they did. And there was one very special message: "I just want you to know what has happened. That day, I sent a message to a friend who I hadn't heard from for a while. She and I talked for a whole day back and forth on messages and then on the phone. She said she was so incredibly sad. Nobody has spoken with her in two weeks. By the tone of her voice, and by the conversations we were having, I think she was about to take her own life . After our conversation, she has agreed to talk to someone. Your message of kindness has saved her. I can't wait to tell you how thankful I am for people like you in the world, who care when nobody else will. I am proud to call myself your friend. Thank you! " I didn't quite know what to say after reading the message. I was wondering how best to use it for greater good. I decided that sharing what we have done is the most powerful way. I know that I am a cheerleader when it comes to making the world a better place with kindness, because if I help someone, it makes me feel better. I do it because I need to feel better.
Answer: No one responds to her friend.
