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: For the kids in Matt Marciano's sixth-grade social studies class, Thanks-giving is a time for great ideas. "We look at different foods that people eat around the world," says Marciano. "The lesson," he explains, "teaches students to admit that some people are unlucky. And it also gets them thinking about Thanksgiving, about their lives, and about their biggest homework of the year--to find a way they can change the world." Last year, 12-year-old Christian D. taught basic soccer skills to 63 kids with cancer. Christian's classmate Brianna used the money she had raised to buy 56 teddy bears. She donated them to a woman's shelter. Both students say the experience taught them something they'll never forget: When we give something to others, we're really giving thanks. And giving thanks feels good. "Helping the woman smile, if just for a day, made me feel like I could make a difference," Brianna says. "And it taught me that I should always be thankful for what I have." Brianna's happiness is something Jeffrey Froh knows about. Froh studies how gratitude affects a person's mind and attitudes. Those who are thankful are more likely to help others. Grateful people and kids in particular are healthier and happier than those who are not. "Grateful kids tend to be happier and more satisfied with their lives," Froh says. "Kids who give thanks are happier with school, their families and their friends. Grateful children also feel less envy toward others, are less likely to be depressed and even do better in school." "To experience gratitude," says Froh, "a couple of things have to happen. First you have to notice that there is goodness in your life. Then you have to admit that the reason for that goodness lies partially outside of yourself."
Answer: They thought of ideas for helping other people.
Output:
How did the students celebrate Thanksgiving in Marciano's class?
