Article: Worrying about how you'll perform on a math test may actually contribute to a lower test score, US researchers said on Saturday. Math anxiety--feelings of dread and fear and avoiding math--can weaken the brain's limited amount of working capacity, a resource needed to calculate difficult math problems, said Mark Ashcrafi, a psychologist at the University of Nevada Las Vegas who studies the problem. "It turns out that math anxiety occupies a person's working memory," said Ashcraft, who spoke at the annual meeting of the American Association for the Advancement of Science in San Francisco. Ashcraft said while easy math tasks such as addition require only a small part of a person's working memory, harder calculations require much more. Worrying about math takes up a large part of a person's working memory stores as well, _ disaster for the anxious student who is taking a high-stakes test . Stress about how one does on tests like college entrance exams can make even good math students choke. "All of a sudden they start looking for the short cuts," said University of Chicago researcher Sian Beilock. Although test preparation classes can help students get over this anxiety, they are limited to students whose families can afford them. Finally, she said, "It may not be wise to rely completely on scores to predict who will succeed." While the causes of math anxiety are unknown, Ashcraft said, "People who manage to get over math anxiety have completely normal math ability." Question: Sian Beilock points out that stress _ . Yes or no, is the answer "has side effects on students in college entrance exams"?
No

Article: During the outbreak of 2009-2010 H1N1 or "swine flu", the same virus that caused mild coughing and sneezing in some patients proved deadly for others. It highlighted a medical mystery: why are some people more fit to handle the flu than others? British and American researchers think they have a clue. Reporting on Sunday in the journal Nature, researchers say they've found a gene that influences our ability to fight against flu illness. The gene, called IFITM3, is the "important first line of defense" against the flu, researcher Paul Kellam of Britain's Sanger Institute told Reuters. The IFITM3 protein prevents flu viruses from reproducing in cells. So, if you have a high amount of IFITM3, you're in luck, since it weakens the spread of the virus; a low amount can lead to more rapid viral reproduction, causing severe flu symptoms, according to Kellam. Scientists first found in gene studies that IFITM3 played a role in resistance to flu and other viruses. In experiments in mice, they showed that when mice were raised to lack the IFITM3 gene and then infected with influenza, the animals developed more severe lung infection from flu, compared with mice that had the gene. To figure out the role of IFTTM3 in humans, researchers then studied the IFITM3 genes of 53 patients with the flu in 2009-2010. They found that these patients were more likely to have a variant of the IFITM3 gene -- which makes people more vulnerable to flu -- compared with the general population. According to evidence from large genetic databases, about 1 in 400 people carries this IFITM3 variant, the BBC reports. "Our research is important for people who have this variant as we predict their immune defenses could be weakened to some virus infections," said Kellam. The Findings also suggest that a drug that functions as IFITM3 could help increase resistance to flu and other viruses, including deadly ones like H5N1 flu. Question: You are less likely to get infected with H1N1 if _ Yes or no, is the answer "you have a high amounts of IFITM3"?

No

Ques: Article: At 2:30 December 5, 1945, five US Navy training planes took off in clear weather from the base Lauderdale, Florida. The planes flew east over the coast... and disappeared. The group was Flight 19, on a run between Florida and Bahamas. Tailor was the group leader. At about 3:40, Tailor reported that his compasses were not reading properly. The other planes followed their leaders aimlessly, first east, then west, then northeast over the ocean, as Tailor tried to make sure of the direction by radio. Then, suddenly Tailor was heard to give orders to dive... Quickly, two giant Martin seaplanes were sent up to search for Flight 19. Several hours later, the wind became strong and visibility dropped. A return to base was ordered. But only one of the Martin seaplanes landed. Four days later, the Navy and Coast Guard _ a 100,000 square--mile area with more than 100 planes and ships. No sign was ever shown of the missing planes. Today, people have noted the disappearance of many ships and planes in the southwest part of the North Atlantic and began to call this area the Bermuda Triangle. The points of the triangle are Bermuda, Puerto Rico and a particular place in the Gulf of Mexico, west of Florida. It is a two--faced water world of tiny islands, bright beaches and beautiful waters. Yet thick fogs, powerful currents and sudden storms are hidden behind this smiling surface. Question: How many planes disappeared altogether that day? Yes or no, is the answer "Six"?
Ans: No

Ques:Article: My conscience was pricked again on a tour of Venice in 2010. I had taken refuge from the crowds in a quiet canal-side cafe. Outside the cafe was an old woman kneeling on the ancient cobbled stones, begging. Steady streams of tourists were walking past her. A lone young back-packer stood away from the throng drinking something, but I noticed he was also observing the woman. A tourist group glanced at the woman and walked on. Another group of tourists arrived and, again, walked past her. The backpacker watched. Then, as I prepared to leave, I stopped at the sight of the backpacker stepping forward and placing some money in the woman's cup. He did this rather ostentatiously , just before the arrival of another tourist group. I watched as the leader of the group stopped and put some money in the cup. Having been shown the way, other tourists followed suit and added more coins to the woman's cup. The young backpacker repeated this process in front of the next tour party going past. Once again, the subtle peer pressure worked on the tourists, who all added coins to the cup. His work done, the young man walked over to the old beggar woman, patted her shoulder and said, "I hope that helps a bit." I don't know if the woman understood his English or realized what had just happened, but I did. I placed some money in the woman's cup and continued my travels, light-hearted after witnessing such an astute act of caring. Question: The author went to a quiet canal-side cafe to _ . Yes or no, is the answer "get away from the crowds"?

Ans:
Yes
