Example Input: Article: Characters in novels don't always do what the writer wants them to do. Sometimes they cause trouble, take on lives of their own, or even work against the writer. It's not just a problem for inexperienced authors: famed children's novelist Roald Dahl said he got the main character in his bookMatildaso "wrong"that when he'd finished his first version, he threw it away and started again. Of course it's not the characters' fault. The problem lies with the author. Take Stephen King, who admitted that writing working-class characters is more difficult nowadays because his own circumstances have changed. "It is definitely harder,"King said."When I wroteCarriemany years ago, I was one step away from physical labour." This is also true for characters' ages, added King."When you have small children, it is easy to write young characters because you observe them and you have them in your life all the time. But your kids grow up, it's been harder for me to write about this little 12-year-old girl in my new book because my models are gone." For other authors, such as Karen Fowler, there's one quality that can stop a character in its tracks: boredom."I had particular problems with the main character in my historical novelSister Noon,"she says."She had attitudes about race and religion that seemed appropriate to me for her time and class, but they were not attitudes I liked. Eventually I grew quite bored with her. You can write a book about a character you dislike or a character you disagree with, but I don't think you can write a book about a character who bores you." According to Neel Mukherjee, it was Adinath, a character inThe Lives of Others, who made him work the hardest."I think I struggled because it's difficult to write a character whose most prominent personal feature is weakness, as Adinath's is, without making that feature define him,"Mukherjee says. But a troublesome character is far from an unwelcome guest, he continues, arguing that "when characters work against the author they come alive and become unpredictable". "That is a fantastic thing to happen,"Mukherjee says."I celebrate it. It is one of the great, lucky gifts given to a writer."

Example Input: Article: There are many traditions around the holidays. "Holiday traditions" are things that people do every year during a holiday such as Christmas or Thanksgiving. At Christmas, for example, many people put up a Christmas tree or Christmas lights. These are Christmas traditions that have been going on for many years. But there is a "new" Christmas tradition that has become very popular: _ , a TV channel that shows nothing but a large log fire, blazing in a fireplace. People put it on their TV and it makes them feel like they are watching and listening to a crackling fire. It makes them feel calm and comfortable. The origin dates back to 1986 in Canada. At that time, not very many people knew about it or watched the channel. Today, more than three million people watch the firelog channel during the winter holiday season. That year, the firelog channel was created to give the workers in the company that is now called Shaw Cable, a break at Christmas. By running the firelog during the holidays, everyone could go home for a few days and enjoy a bit of time off. At that time, it was only broadcast to people in Edmonton but today it reaches people across Canada and beyond. This year, the Shaw firelog was updated. It is pretty high tech. Although it's still really just a fire log that has been filmed, it has its own Twitter account (@ShawFireLog), its own Facebook page and it even has a computer App so you can see the burning log on a smartphone or a tablet. The Shaw firelog will burn until Jan. 5 on Shaw Cable, channel 222.

Example Input: Article: Researchers have found more evidence that suggests a relationship between race and rates of lung cancer among smokers. A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking. It compared their risk to whites, Japanese, Americans and Latinos. The study, however, found almost no racial or ethnic differences among the heaviest smokers. These were people who smoked more than thirty cigarettes each day. Other comparisons have shown that blacks are more likely than whites to get lung cancer from smoking. But the scientists say few studies have compared the risks among Native Hawaiians, Asians and Latinos. Researchers at the University of Southern California and the University of Hawaii did the new study. The New England Journal of Medicine published the findings. The eight-year study involved more than 180,000 people. They provided details about their tobacco use and their diet as well as other information. They included current and former smokers and people who never smoked. Almost 2,000 people in the study developed lung cancer. Researchers say genetics might help explain the racial and ethnic differences. There could be differences in how people's bodies react to smoke. But environmental influences, including the way people smoke, could also make a difference. African-Americans and Latinos in the study reported smoking the fewest cigarettes per day. Whites were the heaviest smokers. But the scientists note that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer. Many researchers disagree not only about the effect of race on the risk of disease, but even about the meaning of race. Yet scientists know that some diseases affect different groups differently. And some drug companies have begun to develop racially targeted medicines. Last June, the United State Food and Drug Administration approved a drug designed to treat heart failure in black patients. The name is BiDil. The agency called it "a step toward the promise of personalized medicine".
Question: Which of the following orders is right from higher to lower risk of having lung cancer?

B
