Article: NOT all math skills are learned in the classroom. Some of them come naturally. Consider the split-second calculations you make when you estimate the number of empty seats on the school bus or the number of cookies in a cookie jar. These estimates can often be done without counting. That's because humans are born with the ability to closely guess the number of items in a group. Researchers call this ability a person's "number sense". To see how a person's inborn number sense might be linked to mathematical performance in the classroom, psychologist Justin Halberda and his colleagues from Johns Hopkins University in prefix = st1 /Baltimore,USran some tests. The scientists asked 64 14-year-olds to look at images of yellow and blue dots that flashed on a computer screen for a fraction of a second. Each image contained between 10 and 32 dots that varied in size. Some images contained twice as many blue dots as yellow dots. In other images, however, the number of blue and yellow dots was nearly equal. For each image, the students were asked to estimate which color1 had more dots. The scientists found a wide variation in how well students could pick the color1 with the most dots. The scientists then looked at the students' math scores dating back to kindergarten. Children that performed best in the image test also scored the highest in standard math tests. The same finding held true at the other end of the spectrum . Students who didn't score well on the image test received lower math scores. The study was the first to show a link between a person's inborn number sense and his or her achievement in formal math training. Does this connection mean that one cannot be good in math if they have a weak number sense? Or that having a strong number sense is a guarantee for good grades in math? The answers are not clear. While scientists continue looking at the possible links between a person's number sense and math achievement, one thing is certain: Doing lots of math homework will _ your chances of success.
Question: Which of the following is not true according to the passage?
Options: (A) Everyone has an inborn number sense. (B) Those who have a strong number sense are sure to do well in math. (C) Some of the math skills are inborn. (D) Doing a lot of math exercises may help to learn math well.
Asnwer: B
answer:
Yes

Article: Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children's bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging . Scientists measured this by studying the ends of children's chromosomes , called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry. Telomeres are special DNA sequences which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies. Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person. In this study, researchers examined whether exposure to violence could make children's telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner, physical maltreatment by an adult or bullying. Researchers measured the children's telomeres--in cells obtained from the insides of their cheeks--at ages 5 and 10. Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers. Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says. The study confirms a smallbutgrowing number of studies suggesting that early childhood hardship imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School.

Options: (A) violence leaves scars on a child's mind (B) violence can speed up a child's aging (C) hardship can change a child's aging (D) hardship has a long-term effect on children

Yes

Article: According to Andrew, it never would have happened if he had not had a flat tire on Highway 10 last night at about 7:30. He was on his way to attend a three-day sales meeting when he had the flat. tyre. Unfortunately, he did not have a spare, so he pushed the car off the road, locked it up, and managed to thumb a ride back to Pine Grove. It was after eleven o'clock when he finally got home, and it was then that his real problems started. When Andrew left home at about 5:30, he had told his wife not to expect him back until Thursday or Friday. Knowing that his wife was nervous about staying in the house alone at night, Andrew took the precaution of checking all the windows in the house to be sure they were locked, so that he could report to his wife that the house was secure. He convinced his wife that the house was burglar-proof, and that she would be perfectly safe, providing she bolted the front door as soon as he drove away. Andrew's only thought as he made his way in the dark to his front door was how surprised his wife was going to be to see him, since he was not supposed to be back until Thursday or Friday. He had forgotten about the bolt on the front door. When he turned his key in the lock and the door wouldn't _ he remembered the bolt. And he remembered that he had carefully locked all of the windows. Although Andrew didn't know it at the time, a next-door neighbor had seen him approaching the house and had watched him go up the steps to the front door. In the dark, it was impossible for the neighbor to recognize Andrew, and, besides, the neighbor knew that Andrew had gone out-of-town for a three-day meeting. As a matter of fact, Andrew had asked the neighbor to keep an eye on the house while he was gone. Finding that he couldn't get in, Andrew began pounding on the front door to get his wife to open the door. According to Andrew, however, his wife is a very sound sleeper, and he knew it was going to be hard to wake her up. In the meantime, because of all the noise he had been making, the neighbor was convinced that somebody was trying to break into the house; so she called the police. When we talked to Andrew at the country jail this morning, he said that he still didn't understand how the police managed to circle the house without his seeing them. He stated that he had decided the only way to get in was to break one of the dining room windows, and that he was about, to hurl his briefcase into the window to break it when two of the officers grabbed him from behind. Andrew could not make the officers believe that he lived there; so they took him off to jail. Apparently, he did succeed in convincing them that they ought to wake up the woman in the house to check his story. But there was no answer when they knocked at the door. He tried to explain to them that his wife was a very sound sleeper, but they concluded there was nobody in the house.

No
