Question: Read the article and select the best answer. Article: Motherhood may make women smarter and may help prevent dementia in old age by bathing the brain in protective hormones , U.S.researchers reported on Thursday. Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer's .University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans."Our research shows that the hormones of pregnancy are protecting the brain, including estrogen , which we know has many neuroprotective effects," Kinsley said. "It's rat data but humans are mammals just like these animals are mammals," he added in a telephone interview."They go through pregnancy and hormonal changes." Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer's and other forms of age-related brain decline. "When people think about pregnancy, they think about what happens to babies and the mother from the neck down," said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida. "They do not realize that hormones are washing on the brain.If you look at female animals that have never gone through pregnancy, they act differently toward young.But if she goes through pregnancy, she will sacrifice her life for her infant--that is a great change in her behavior that showed in genetic alterations to the brain." Question: Which title is the best for this passage? Options: A: Do You Want to Be Smarter? B: Motherhood Makes Women Smarter C: Mysterious Hormones D: An Important Study
Answer: B

Question: Read the article and select the best answer. Article: While success is surely sweeter than failure, it seems failure is a far better teacher, and organizations that fail spectacularly often flourish more in the long run, according to a new study by Vinit Desai, assistant professor of management at the University of Colorado Denver Business School. Researchers have found that people missing their goals perform much better in the long run. That is because they gain more knowledge from their failures than their successes and the lessons are more likely to stay longer in their minds. "We found that the knowledge gained from success was often fleeting while knowledge from failure stuck around for years," said professor Desai, who led the study. "But companies often ignore failure. Managers may fire people or turn over the whole workforce while they should treat the failure as a learning opportunity." Prof Desai compared the flights of the space shuttle Atlantis and the Challenger. During the 2002 Atlantis flight, a piece of insulation broke off and damaged the left solid rocket booster but didn't influence the program. There was little investigation. The Challenger was launched next and another piece of insulation broke off. This time the shuttle and its seven-person crew were destroyed. The disaster led to a major investigation resulting in 29 changes to prevent future disasters. The difference in response in the two cases came down to this: Atlantis was considered a success and the Challenger a failure. "Despite crowded skies, airlines are extremely reliable," he said. "The number of failures is extremely small. And past researches have shown that older airlines, those with more experience in failure, have a lower number of accidents." Prof Desai doesn't recommend finding out failure in order to learn. Instead, he advises organizations to analyze small failures to collect useful information rather than wait for major failures. Question: Fewer accidents happen to older airlines in that _ . Options: A: their planes couldn't fly high in the sky B: they gained much from experience in failure C: their planes were often checked by the experts D: they were unpopular among passengers
Answer: B

Question: Read the article and select the best answer. Article: The arts, especially music, should be part of every school's lessons at every grade level. Students would be much smarter if they had some musical experience. They could improve their classroom skills, like paying attention and following directions. People develop all these skills when they learn music. Making music also lets children use their imagination. It provides students with a chance to try out their own ideas. Music not only makes children better students, but also gives them something positive to do. In a music program, children can be part of a band instead of joining a gang . Parents can enjoy listening to their children's music instead of seeing them _ a computer or TV screen. In a school band, students get to be part of a team. They can get along well with old friends and make new friends through music. Music builds self-confidence, too. It gives children a sense of achievement and success. Making music is something for them to be proud of, and it lets kids practice performing in front of an audience. Music gives children an opportunity for self-expression, and that helps develop their self-confidence. Once again, music is important because it can make children better students, give them something positive to do, and build their character. That is why music should be offered in every single grade in every school. Question: What's the best title of this passage? Options: A: Music is a must as a course at school B: Music builds children's self-confidence C: Music makes students much smarter D: Learning music and making music
