TASK DEFINITION: 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.
PROBLEM: Article: We know that cigarette smoking kills. So, producers made electronic cigarettes as a safer smoking choice - safer than tobacco. Although e-cigarettes contain the drug nicotine like cigarettes, they do not use tobacco and you do not light them. They are powered by battery . However, if e-cigarettes are so safe, why has the United States Center for Disease Control(CDC) seen an increase in telephone calls about e-cigarette poisonings? The answer is children. Most of the calls are from people worried about children who have played with the devices, In the period of one month this year, the Center said 215 people called the Center with e-cigarette concerns. More than half of these calls were for children aged five and younger. The devices had made them sick. Tim McAfee is director of the Center's Office on Smoking and Health, He says the problem is regulation. Meaning, the U.S. federal government does not control e-cigarettes even though they contain liquid nicotine. Mr.McAfee adds that liquid nicotine is a well-known danger. Mr.McAfee explains that nicotine poisoning happens when it gets into the skin, gets into the eyes or is swallowed. It can cause stomach pain or a sense of unbalance. And too much nicotine can kill, Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do.He notes that almost 500,000 Americans die each year from cigarettes. "So, cigarettes are the winner in that contest." E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes. So, the U.S.Surgeon General Boris D. Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use. But McAfee worries that teenagers may think electronic cigarettes are harmless. They could become addicted to the nicotine and then start smoking real cigarettes. In other words, he fears that for young people fake e-cigarettes could be a "gateway" to the real thing.
Answer: Cheaper.

SOLUTION: What do the producers think of e-cigarettes?

PROBLEM: Article: Snapshots, the new fashion for an artistic portrait photo: Take it underwater. Zhang Xiaomei, a 20 something Shanghai native who works in the media industry, tried it out twice. "It was a completely different experience," says Zhang of her first such experience last May. "You get the feeling that you're cut off from the rest of the world. But also it s romantic and like a fairy tale." She then successfully convinced her husband to be to have their wedding photos taken underwater a couple of months after her first try. "Can you imagine a 1.87-meter-tall man trying out something like a fishtail under the water?" Zhang says, laughing. A commercial underwater photo portrait is perfect for post 80 and post 90 generations who adore taking snapshots, but are looking for new ways to be artistic, says Ai Cheng, owner and photographer of No.55 Underwater Photography in Shanghai. Ai opened a studio in Shanghai's suburb of Songjiang two years ago, building a 5-meter- deep, fan-shaped pool equipped with heating facilities to start up the business. A 30-minute training on how to smile under the water so that you won't drink too much water and how to open your eyes underwater is offered in his studio for those who don't know how to swim. Ai says most of his customers are female--half of them coming for an artistic portrait photo and the rest for wedding pictures. "Some of them drag their boyfriends or husband-to-be, who are unwilling to go down to the water, to shoot as well," he says.

PROBLEM: Article: Reflecting on the past about those decisions or actions that can't be reversed and being occupied with thoughts of "What if?" is no way to live. But there are a few things in life I'd probably do differently if I had the chance. I once majored in architecture -- something I had been crazy about for as long as I could remember -- and then I suddenly had a change of heart. I made an appointment with my adviser, and told him I was no longer certain I wanted to pursue a career in architecture. "Don't give up on your childhood dream!" "He's right," I thought. "I should just stick it out and I shouldn't disappoint the little girl who once loved architecture." It was awful. I was _ , holding on to a childhood dream that had long since faded. When I talked with a friend about it a year later, he asked: "Right now, what do you want to do with your life?" That's when I came to the realization that dreams change over time and that you should give up the childhood dream if it's not what you want as an adult. Luckily, it wasn't too late. After some serious thought, I changed my major to journalism. It wasn't something I had always imagined myself pursuing -- but at that moment, it was what I wanted. We grow up, and sometimes our dreams change -- and that's perfectly OK. You just need to ask yourself every once in a while, "Is this still what I want?" If the answer is no, move on and start chasing a new one.
Answer: She didn't want her childhood dream to fade.

SOLUTION:
Why didn't the author change her major immediately?
