input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: The massive magnitude 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil. These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake. Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved. The quake's epicenter was in a region of South America that's part of the so-called "ring of fire," an area of major seismic stresses which encircles(,) the Pacific Ocean. All along this line, the plates on which the continents move press against each other. Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP. Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes. "We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused." said Brooks. Options: A It is under the leadership of Mike Bevis. B It observes earthquakes worldwide. C It is designed to watch climate changes. D It mainly studies the Pacific Ocean. Answer: A It is under the leadership of Mike Bevis. Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Mona Lisa, the mysterious woman in Leonardo da Vinci's 16th century masterpiece, had just given birth to her second son when she sat for the painting, a French art expert said on Tuesday. The discovery was made by a team of Canadian scientists who used special infrared and three-dimensional technology to study the paint layers on the work, which now sits in the Louvre museum in Paris. Bruno Mottin of the French Museums' Center for Research and Restoration said that on very close examination of the painting it became clear that the Mona Lisa's dress was covered in a thin transparent gauze veil. "This type of gauze dress was typical of the kind worn in early 16th century Italy by women who were pregnant or who had just given birth. This is something that had never been seen up to now because the painting was always judged to be dark and difficult to examine," he told a news conference. "We can now say that this painting by Leonardo da Vinci was painted in memory of the birth of the second son of Mona Lisa, which helps us to date it more precisely to around 1503."The young woman with the ambiguous half smile has been identified as Lisa Gherardini, wife of Florentine merchant Francesco de Giocondo. She had five children. "People always wrote that Mona Lisa had allowed her hair to hang freely over her shoulders. This greatly surprised historians because letting your hair hang freely during the Renaissance was typical of young girls and women of poor virtue ," he said. The team had hoped to discover more details about Leonardo's painting techniques, which the artist used to create a hazy effect. But scientist John Taylor said the team had been disappointed by the lack of brush stroke detail on the painting. Options: A a woman of poor virtue B da Vinci's second wife C a woman who was pregnant D the wife of Florentine merchant Answer: D the wife of Florentine merchant Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Older people with hearing loss may suffer faster rates of mental decline. People who have hearing trouble suffered meaningful impairments in memory, attention and learning about three years earlier than people with normal hearing, a study published online January 21 in JAMA Internal Medicine reveals. The finding supports the idea that hearing loss can have serious consequences for the brain,says Patricia Tun of Brandeis University in Waltham,Mass., who studies aging. "I'm hoping it will be a real wake-up call in terms of realizing the importance of hearing. " Compared with other senses, hearing is often overlooked, Tun says. "We are made to interact with language and to listen to each other, and it can have damaging effects if we don't." Frank Lin of Johns Hopkins School of Medicine and colleagues tested the hearing of 1,984 older adults. Most of the participants, who averaged 77 years old, showed some hearing loss -- 1,162 volunteers had trouble hearing noises of less than 25 decibels, comparable to a whisper or rustling leaves. The volunteers; deficits reflect the hearing loss in the general population: Over half of people older than 70 have trouble hearing. Over the next six years, these participants underwent mental evaluations that measured factors such as short-term memory, attention and the ability to quickly match numbers to symbols. Everybody got worse at the tasks as time wore on, but people with hearing loss had an especially sharp decline, the team found. On average, a substantial drop in performance would come about three years earlier to people with hearing loss. Lin cautions that the study has found an association between hearing loss and mental abilities; the researchers can't conclude that hearing loss directly causes the decline. Yet more and more studies are turning up ways that diminished hearing could damage the brain. A person who can't hear well might avoid social situations, and isolation is known to be bad for the brain. "You gradually become more socially withdrawn, " Lin says.... Options: A social isolation B hearing loss C memory loss D speech impairment Answer: A social isolation Question:???
output answer:
Dementia and cognitive decline mainly result from _ .
