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 Input: Article: World Wrestling Entertainment is the largest professional wrestling organization in North America. It was called World Wrestling Federation until it changed its name because of a legal dispute. Its more than one hundred wrestlers fight each other in competitive matches that are written and practiced before they are performed. Professional wrestlers are athletes but act as entertainers. They are not seeking athletic records, but instead want to excite an audience. To do this, they use unusual names and wear special clothing during wrestling matches. These wrestlers include the Stone Cold Stunner and the Undertaker. Most professional wrestling matches are between two men or two women. They fight inside an area called a ring that is separated from the audience by ropes. Each match continues until one wrestler forces the other's shoulders to the floor and holds them there for a count of three. Most World Wrestling Entertainment matches continue for only about four to seven minutes. An organization official called a promoter decides before the match who will win. But who wins and who loses is not the important thing in professional wrestling. The important thing is that the audience enjoys the pretend fight. Some wrestlers rarely win, but continue to be popular. Not all wrestling matches are between two people. Some are called tag team matches and involve teams of two, three or four wrestlers. Another kind of match is called a battle royal. It involves thirty to sixty wrestlers competing against each other. A wrestler loses when he or she is thrown out of the ring. The winner is the last wrestler still standing.
Answer: Because maybe there was another name similar to it.
Example Output: Why did World Wrestling Federation change its name?

Example Input: Article: Crystal Ear One day a friend asked my wife Jill if I wanted a hearing aid. "He certainly does,"replied Jill. After hearing about a remarkable new product, Jill finally got up the nerve to ask me if I'd ever thought about getting a hearing aid. "No way,"I said. "It would make me look 20 years older.""No, no"she replied. "This is entirely different. It's Crystal Ear!" Jill was right. Crystal Ear is different ---- not the old-styled body worn or over-the-ear aid, but an advanced personal sound system so small it's like contacts for your ears. And Crystal Ear is super-sensitive and powerful, too. You will hear sounds your ears have been missing for years. Crystal Ear will make speech louder, and the sound is pure and natural. I couldn't believe how tiny it is. It is smaller than the tip of my little finger and it's almost invisible when worn. There are no wires, no behind-the-ear device. Put it in your ear and its-ready-to-wear mold fits comfortable. Since it's not too loud or too light, you may even forget that you're wearing it! Use it at work or at play. And if your hearing problem is worse in certain situation, use Crystal Ear only when you need it. Hearing loss, which is typically prior to teenage years, progresses throughout one's lifetime.

Example Input: Article: Over the years, Brian Wansink, director of the Food and Brand Lab at Cornell University, has studied such things as how far Americans typically drive to buy food, how many times we refill our plates at all-you-can-eat buffets and how we organize our kitchens. In the mid-2000s he famously coined the phrase "mindless eating"(and wrote a book by that name) to focus attention on all the bad dietary decisions we make without really thinking about them. His new book, Slim by Design: Mindless Eating Solutions for Everyday Life, aims to change the design of restaurants, school lunchrooms, office cafeterias and homes so that the mindless choices we make will be more healthful ones. Some examples: Keep kitchen counters clear. No visible snack food, no bread, no nuts--not even breakfast cereal. In Wansink's research, "women who had even one box of breakfast cereal that was visible-anywhere in their kitchen--weighed 21 pounds more than their neighbor who didn't." Trick yourself into drinking less wine. "We tend to focus on the height of what we pour and not the width, so we pour 12 percent less wine into taller wineglasses than we pour into wider wineglasses." And the shape of the glass is not the only variable that affects how much we drink. Wansink writes: "Because red wine is easier to see than white wine, we pour 9 percent less red wine whenever we pour a glass." Wansink said his researchers also found that people ate less at restaurants when sat in well-lighted areas near windows and doors, than in darker areas or in the back. They ate less if they were offered a doggie bag, or to-go box, before they got their meals: apparently the idea of getting a "free" second meal outweighed the impulse to clean their plates. Workers who frequently ate at their desks weighed 15.4 pounds less, on average, than those who didn't. Fruits and vegetables kept on the top shelf of the refrigerator were eaten at higher rates than those on lower shelves. The point, Wansink says, is to consider findings like those and change your environment or habits. Then you won't have to think about it: You'll just eat less.
Answer: Because he intended to help people make more healthful dietary decision.
