Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: In American crime movies, policemen search crime scenes for anything that might belong to a criminal-- bits of fingernail , blood or hair-- in order to find out who they are. What they hope to find is the key to their identity--their DNA. DNA is the chemical that contains a person's genetic makeup. Every person, except for identical twins, has unique DNA information. That is why we can use it to identify someone. There is no doubt that DNA evidence is becoming a very powerful tool for law enforcement officers. In the US, all 50 states and the federal government keep DNA databases of some criminals after they have been convicted . Whenever a crime happens, the police collect DNA from the crime scene and compare this with samples they already have in the criminal database. If they match any suspect in the database, then they've caught their criminal. Even if they don't, the DNA sample can still be used to determine the person's sex, height, hair and eye color1 and other characteristics. This helps police to create a physical profile of the criminal. Some people feel that the database should be made bigger to contain everyone's DNA and help to solve many more crimes. This would also avoid mistakes when someone is wrongly convicted of a crime. DNA doesn't make mistakes. However, other people are worried that it would violate their privacy. Someone's DNA can be used to gather information such as the person's family and ethnic background, whether he or she has a gene mutation or certain genetic diseases, and other personal issues. People are afraid that this information might be used inappropriately. They may fear that employers might read it and treat them differently. People may also be afraid that personal data might get into the hands of insurance firms or loan companies. For example, if they knew from your DNA that you had a genetic risk of a serious disease, they might be able to refuse you life insurance, a loan, or even a job. Clearly, the use of DNA evidence will continue to help the police solve... Question: Which is TRUE according to the article? Options: A: DNA evidence has been widely used in criminal law cases. B: Everyone in the world has their own unique DNA composition. C: In America, anyone who has been convicted must submit a DNA sample. D: America's DNA database is the biggest national DNA database in the world.
Ans: A

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: By the mid-nineteenth century, the term "icebox" had entered the American language, but ice was still only beginning to affect the diet of ordinary citizens in the United States. The ice trade grew with the growth of cities. Ice was used in hotels, taverns , and hospitals, and by some forward-looking city dealers in fresh meat, fresh fish, and butter. After the Civil War (1861-1865), as ice was used to refrigerate freight cars, it also came into household use. Even before 1880, half of the ice sold in New York, Philadelphia, and Baltimore, and one-third of that sold in Boston and Chicago, went to families for their own use. This had become possible because a new household convenience, the icebox, a precursor of the modern fridge, had been invented. Making an efficient icebox as not as easy as we might now suppose. In the early nineteenth century, the knowledge of the physics of heat, which was essential to a science of refrigeration, was rudimentary . The commonsense notion that the best icebox was one that prevented the ice from melting was of course mistaken, for it was the melting of the ice that performed the cooling. Nevertheless, early efforts to economize ice included wrapping up the ice in blankets, which kept the ice from doing its job. Not until near the end of the nineteenth century did inventors achieve the delicate balance of insulation and circulation needed for an efficient icebox. But as early as 1803, and ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an icebox of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his icebox, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool. Question: What can we infer from the text? Options: A: Thomas Moore is the inventor of modern fridge B: The butter produced by Thomas Moored is better in quality than other famers' C: Knowledge of the physics of heat plays an important part in inventing a good icebox D: Before 1880, most of the sold ice was used for family use.
Ans: C

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Attending the Space Camp organized by NASA at prefix = st1 /Huntsville,Alabamais every kid's dream. It gives them the real life experience of what it is like to be an astronaut. It enriches their life with the most meaningful and interesting experiences. Most of these one-week programs are combined with other community programs. As expected, there is an age limit at the Space Camp in Alabamawith the full camp program being offered only to kids of twelve and above. Many of the activities organized at the camp are likely to be difficult for younger kids, and kids need to be old enough to stay for the week away from home. However, some special programs are offered at the center even for younger kids. The programs and activities at Space Camp are to awaken creativity. There are exercises in classes and discussions about the history of the space program. These classes include the Russian space program as well as the United Statesprogram. Trips to the museum are also provided for an educational experience. All those who attend the Space Camp go through a sort of training. They wear space suits to get the feeling of being an astronaut. They are taken into simulators to learn how to fly spacecrafts like the shuttle. And they experience the feeling of weightlessness in the zero gravity simulations. What's more, they even have equipment designed to give them the experience of walking on the moon. Space Camp is an effective and fun way to bring an interest in space and science. Kids will go through a practical program in a learning atmosphere that transports them far away from their location in Huntsville.Alabama. Question: What's the best title of the passage? Options: A: Being An Astronaut Every Kid's Dream. B: Special Training for Space Camp. C: Attending Space Camp in Huntsville,Alabama. D: Special Programs for Youngsters
Ans:
C
