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: Food labels are such a mess that the government is redesigning them, as the ingredient lists are usually too confusing. As a result, a shopper could spend hours in a grocery store watching, calculating, and comparing, and still could not get it right. ShopWell is trying to help by allowing consumers to scan food labels and receive understandable and personalized information. Here's how it works. Register for ShopWell, and enter your age and gender. Add your goals (General health? Or are you trying to lose weight?). Then, note what you want in your diet, such as protein or iron, and what you want to avoid(added sugar, say). Add your allergies and things you cannot accept, and start scanning. Then ShopWell will come up with a clearly personal result: green for a food that is good for you; yellow for foods you can enjoy a little; and red for foods you should avoid. The results are easily understandable and is clean because it's not mixed with ads. Instead, ShopWell makes money by selling data to supermarkets. Its database contains 350,000 products, the app has been downloaded 1.3 million times, and the company claims a scan every two seconds "in stores such as Walmart, Whole Foods and 7-Eleven," in the words of marketing manager James Allgood. One of the first items I scanned was So Delicious Coconut Milk Creamer, which I buy because I'm lactose intolerant. It turns out it's only a little suitable for me -- because of its 1 gram per serving of added sugar. I'm not sure I'll give it up. But Ididask the app to watch for added sugar, and it's doing its job. One _ to ShopWell is that the scanner often doesn't work for items from Costco or Trader Joe's. Meanwhile, Some user reviews say that it doesn't cover enough allergies.
Answer: Because consumers can hardly make sense of the information on the food labels.
Solution:
Why do consumers hesitate long when deciding which food to purchase in a shop?
