Read the following article and select the best answer. Article: New crime prediction software should reduce not only the murder rate, but the rate of other crimes. Developed by Richard Berk, a professor at the University of Pennsylvania, the software has already used in Baltimore and Philadelphia to predict which individuals on probation or parole are most likely to murder and to be murdered. "When a person goes on probation or parole he is supervised by an officer. The question is 'what level of supervision is appropriate?'" said Berk. It used to be that parole officers used the person's criminal record, and their judgment to make decisions. "This research replaces those _ ," he said. Technology helps determine level of supervision. On average there is one murder for every 100,000 people. Even among high-risk groups the murder rate is one in 100. Predicting such a rare event is very difficult, but advances in computer technology works. Years ago, the researchers made a dataset of more than 60,000 various crimes. Using the software they developed, they found some much more likely to commit murder when paroled or probated. They could identify eight future murderers out of 100. Berk's software examines roughly two dozen variables , from criminal record to geographic location. The type of crimes, and more importantly, the age at which that crime was committed, were two of the most predictive variables. "People assume that if someone murdered then they will murder in the future," said Berk. " What really matters is what that person did as a young individual. Predicting future crimes sounds well. But we aren't anywhere near being able to do that." "Berk's scientific answer leaves policymakers with difficult questions. By labeling one group of people as high risk, and supervise them closely, there should be fewer murders, which the potential victims should be happy about. It also means that those high-risk individuals will be supervised more aggressively. For human rights advocates, that means punishing people who, most likely, will not commit a crime in the future," said... Question: For 650 people with crime records, how many potential murderers would the software find? - 6.5. - 13. - 52. - 65.
(A).
52.

Read the following article and select the best answer. Article: I believe that my country, Poland, is a perfect example for a place where food is particularly important. When we were little children, we began to understand how much a loaf of bread meant to our parents--to some it might sound silly but for me the custom of kissing bread before you started cutting it was simply amazing. It's not so common nowadays to treat food that way, since you hardly ever bake your own bread. Besides, everyone would call you crazy if you tried to kiss every bread roll before you ate them! But though we no longer make our food from scratch , some customs have been kept--that's why I feel so sorry every time I have to throw any food away--even though I no longer live with my parents and nobody would blame me for this anymore! Many people of our nation are still working as farmers, eating what they grow and harvest and therefore enjoying everything more. It's widely known that you value more anything that needs your effort in the first place. In most homes in Poland, especially those of farmers, the whole family would try and have their meals together--extremely difficult now, but so rewarding ! You can share other members' troubles and successes, give your children some attention, or just sit down for a moment instead of rushing through life aimlessly. Furthermore, your body, and stomach in particular will be very grateful for such a time! In Poland, a wedding, Christmas or even a birthday is celebrated with a great meal. Women in the house get together and cook, sometimes for a few days before the event, and the extremely good or unusual food will be remembered and widely talked about. You cannot over-value the importance of food in the country. What's more, almost everyone in Poland will be as interested in the topic as I am. Question: From the text, we can learn that, in Poland, _ . - most meals can be interesting topics for a long time - the whole family often have meals together nowadays - it's common for women to get together to cook for a few days - family members can know more. about each other by having meals together
(A).
family members can know more. about each other by having meals together

A team from the School of Dentistry's Violence Research Group studied drinking habits in children aged 11 - 16 in England. They found not only a link between drink and violence but also that children who drank were more likely to be hit, even if they weren't violent themselves. The researchers are now calling for measures to prevent alcohol misuse to reduce injury risk. Current policy focuses on reducing aggression but this research shows that there should be equal effort to reduce victimization. More than 4,000 children were surveyed at 13 schools at four local authorities in the North, the Midlands, London, and the South. The study found that 25% of 11-year-olds were drinking monthly and 3.6% daily, with 12.8% admitting to getting drunk 3 to 5 times a year. By the age of 16, 40% were drinking weekly and 6.2% were drinking every day. The research also showed 22.6% of 16-year-olds were getting drunk more than 21 times a year. The study, which has just been published in the Journal of Adolescence, found a strong link between frequency of drinking and frequency of hitting other people. However, children who reported drinking monthly were also three times more likely to be hit. Adolescents who drank but didn't get into fights were more likely to be hit than those who did fight. Professor Jonathan Shepherd, who led the research, said a lot of previous alcohol-related violence work had focused on the offenders rather than the victims. His team is calling for more prevention work from parents and teachers in the first two years of secondary school by taking advantage of the "teachable moment", that is, immediately after a student has missed school because of drunkenness. Previous work by Professor Jonathan Shepherd has shown drinkers may be more at risk of violence because of reduced physical co-ordination, poor decision-making in threatening situations and isolation while out late at night. He...
