Input: Consider Input: Article: Head held high, hands firmly gripping her walker, Mary Arnott, 99, walks slowly with dignity through the women's changing room at the Etobicoke Olympium pool, past the teenage girls who have been blow-drying their hair for half an hour, into the mist of the showers, then out the door and first one into the heated pool. She jumps over to the shallow end, stopping to talk to friends--everyone knows Arnott here; she swims twice a week and treats it as a job--about their children, the viciousness of bridge and their health. In fact, Arnott is an exception to the exception. Not only has she lived 20 years past the average lifespan for Canadians, she's healthy, her mind is sharp and she lives independently. Born in Brooklyn on May 28, 1909, Arnott was raised on Staten Island. She survived scarlet fever , helped bring up four siblings after her mother died in 1923 and worked as a secretary in New York City for 12 years, earning$35 a week and a$150 bonus at Christmas. Now she's happy living in a one-room apartment with a kitchen and a bathroom in her daughter's house. She wears a hearing aid, does the cryptic crossword with a magnifying glass, and can't really explain why she has live so well so long. Until recently, she has still liked to drink red wine--she used to drink two glasses before supper each day. It's more likely genes, she admits. Her interest in other people and life in general may have had something to do with it. Asked if a star photographer can take her picture at the pool, Arnott seems cheerful. "I look good in a swimsuit," she says, nodding her head firmly. "I look better in a swimsuit than I do in pants. "

Input: Consider Input: Article: Heavy rains have caused disasters across China this summer, bringing the worst landslides in decades. The most deadly disaster happened on August 8 when a big landslide hit Zhouqu County in Gansu province, killing at least 1,407 people. On August 18, landslides hit Gongshan, a town in northwestern Yunnan. At least 38 people were killed and 54 are missing. Heavy rains also caused landslides in several counties in Sichuan province. People were forced to evacuate to safe places. Landslides and devastation Landslides take place when dirt and rocks slide down a slope together. Sometimes these landslides are small, and hardly noticeable. Other times however, they can be massive, involving the entire side of a mountain. Landslides can be caused by a number of different things. Often rain, which adds weight to the side of a slope, can cause one. Other times they might be caused by erosion .When a stream slowly removes the base of a slope, it weakens the entire side of the mountain. As a slide moves down a mountain slope, it can pick up great speed and energy. Some slides travel at a speed of 300km an hour. The resulting winds can be so powerful that they are known to strip the leaves off surrounding trees. Earthquakes and landslides Some experts think the landslides in Sichuan were related to the magnitude-8.0 Wenchuan earthquake on May 12, 2008. The quake has caused a change in the structure of the Earth's surface, making it more likely that land will slide in the rain, according to geologist Xu Qiang of the Chengdu University of Technology. Landslides pose threats to 140 cities and towns in the country, one quarter of which are in Sichuan, said Wei Fangqiang, a researcher with the Chinese Academy of Sciences. Landslide prevention If you want to avoid being a landslide victim, the easiest thing to do is avoid living on slopes or close to mountains. If you live in a landslide-threatened area, try not to water the slopes if possible. If there are large rocks on the slopes above your house, remove them so that they don't cause damage if they fall. It might also be helpful to plant trees on the slopes. Over time, the tree roots may make the soil firmer.
Question: The landslides around China are mentioned at the beginning of the article to _ .
Options: (A) warn travelers to keep away from those places (B) show that the environment in China is getting worse (C) introduce the topic of landslides (D) express concern for those affected by landslides

Output: C

Input: Consider Input: Article: Lee Humberg, district manager for the U.S. Department of Agriculture's Animal and Plant Health Inspection Service, is the man in charge of figuring out how to remove the flocks of 15,000 to 20,000 Canada geese that could strike planes flying in and out of the New York area. The Port Authority, the agency that manages airport in New York and New Jersey, estimates that there have been as many as 315 bird strikes annually in the past 30 years. Bird strikes have been a hot topic since a US Airways jet suffered a "double strike" and made an emergency landing on the Hudson River in January 2009. All 155 passengers were rescued safely and the flight was called "Miracle on the Hudson". The plane finally ended up at the Carolinas Aviation Museum. The next major bird strike may not have such a happy ending. To thin the flocks, Humberg and his team have tracked down goose nests and killed eggs with corn oil. They've also terrified the birds with dogs, remote-controlled boats and kites that look like eagles. But the only method that effectively decreases the goose population is the one that angers animal lovers the most: gassing hundreds at a time. "If all you are doing is goose harassment every day, it's very frustrating, because you are just playing Ping-Pong with the birds," Humberg told New York magazine. "It's basically an arms race to come up with the tools to deal with them." Now New York City plans to send the geese captured to Pennsylvania to be cooked and distributed at food banks as meals for the poor. That might just be a fate better than flying into a 747 engine.
Question: What can we learn form Humberg?
Options: (A) He does research on geese's living conditions. (B) He makes efforts to protect wild birds. (C) He deals with the danger of birds at airports. (D) He tries to find newer and safer airlines.
Output: C
