Example Input: Article: ,. Three-year-old Teddy Lasry was sleeping in his cowboy outfit yesterday at his family's Fifth Ave.apartment when he shot up in bed screaming.A 3-foot-long black-and-white snake twisted around his left arm and had just bitten his little finger. "The babysitter (a person taking care of children while their parents are away for a short time) was frightened to death," said Teddy's father, David Lasry, who, along with his wife, Evelyn, was at work when the snake appeared about 4:00 pm. The horrified babysitter called 911 and the building's doorman.The doorman and two cable TV workers helped take the snake off the boy's arm and put it in a garbage bag.Police rushed Teddy to Mount Sinai Medical Center, where he spent two hours attached to a heart monitor as a precaution in case the snake was poisonous.It wasn't.Experts at the snakebite treatment center at Jacobi Medical Center in the Bronx, where policemen took the snake, found out it was a non-poisonous California king snake. But how did it end up in Teddy's bed? A little detective work determined that the snake had escaped two weeks ago from its cage in the apartment of a doctor whose family lives four floors below the Lasrys.The apologetic owner said his son's pet snake likely traveled up the water pipes and into his neighbor's apartment."It's a very gentle, very harmless snake," he said."It's handled by our family all the time." David Lasry believed the pet was simply hungry after two weeks of wandering.Evelyn said her son seems to have overcome his fright by thinking of himself as a hero cowboy as he rode in the back of the police car to the hospital. "I told Teddy he's a pretty snake, a nice pet snake who got out of his cage," Evelyn said."But he asked, 'Why did he bite my finger, Mamma?' And I said, 'Because he saw that you are a big boy, Teddy, in your cowboy outfit and he got scared.'"

Example Input: Article: Some years ago industries had more freedom than they have now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They did not have to pay much attention to the health and safety of the people who worked for them. Often new products were dangerous for the people who used them; often conditions in the work place had very bad effects on the health of the workers. Of course sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, they inquire into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however. the new rules came too late to protect the people who died or who became seriously ill. Today many governments have special departments which protect customers and workers.In the U.S, for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work. and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness. but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.
Question: The main topic of the passage is _ .
Options: (A) conditions in the work place (B) the freedom of industries in the past (C) changes in industrial production (D) the safety and health of workers and customers
Example Output: D

Example Input: Article: A new study has discovered that meditation and oxygen sport together reduce depression .The Rutgers University study found that this mind and body combination, done twice a week for only two months,reduced the symptoms for a group of students by 40 percent. "We are excited by the findings because we saw such a meaningful improvement in both clinically depressed and non--depressed students,"said lead author Dr.Brandon Alderman."It is the first time that both of these two behavioral ways have been looked at together for dealing with depression." Researchers believe the two activities have an interactive effect in _ depression.Alderman and Dr.Tracey Shors discovered that a combination of mental and physical training (MAP)enabled students with major depressive disorder not to let problems or negative thoughts defeat them. Rutgers researchers say those who participated in the study began with 30 minutes of focused attention meditation followed by 30 minutes of oxygen sport.They were told that if their thoughts drifted to the past or the future they should refocus on their breathing,enabling those with depression to accept moment-to-moment changes in attention. Shors,who studies the production of new brain cells in the hippocampus--part of the brain involved in memory and learning--says scientists have shown in animal models that oxygen sport exercise keeps a large number of certain cells alive. The idea for the human intervention came from her laboratory studies,she says,with the main goal of helping individuals acquire new skills so that they can learn to recover from stressful life events. By learning to focus their attention and exercise,people who are fighting depression can acquire new learning skills that can help them process information and reduce the overwhelming recollection of memories from the past,Shors says. "We know these treatments can be practiced over a lifetime and that they will be effective in improving mental health."said Alderman."The good news is that this intervention can be practiced by anyone at any time and at no cost."
Question: What made the research so different?
Options: (A) Adopting a way of meaningful talk. (B) Combining the two ways to treat depression. (C) Treating depression with special medicine. (D) Comparing the depressed with the non-depressed.
