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: A man claiming to be a pastor apparently tried to stiff a waiter on a tip, explaining that his work for God allowed him not to leave one. A photo of the receipt, posted to Reddit.com, shows a bill for $34.93 with an automatic 18 percent gratuity (or $6.29) added above a blank space for an additional tip. "I give God 10%," the diner wrote on the receipt, scratching out the automatic tip. "Why do you get 18?" He then wrote "Pastor" above his signature, and an emphatic "0" where the additional tip would be. (The automatic gratuity, however, had already been added to the total.) The Reddit user who submitted the image explained in the comments section that the receipt was part of a total bill for a party of 20, which is why the gratuity was automatically added. "Parties up to eight ... may tip whatever they'd like, but larger parties receive an automatic gratuity," the server wrote. "It's in the computer; it's not something I do." The server added: "They had no problem with my service, and told me I was great. They just didn't want to pay when the time came." Scribbling notes on receipts has become something of a trend. Earlier this month, the manager of a North Carolina Red Robin surprised an overdue pregnant woman by comping her meal. "Once seated, a manager came up to us and started talking," the woman's husband told Consumerist. "He was extremely friendly and jokingly asked my wife if this was her last meal before heading to the hospital." When the check came, a note from the manager next to her portion of the bill read: "MOM 2 BEE GOOD LUC." "It was a pleasant surprise and made my tired-of-being-pregnant wife a little more cheery," the man said.
Answer: He didn't mean to pay the gratuity at all.
Solution:
What did the pastor mean by saying, "I give God 10%. Why do you get 18?"
