Ques:Article: Your cell phone holds secrets about you. Besides the names and numbers that you've programmed into it, traces of your DNA remain on it, according to a new study. DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you --- unless you have an identical twin. Scientists today usually analyze DNA in blood,saliva , or hair left behind at the scene of a crime. The results often help detectives identify criminals and their victims. Meghan J. McFadden, a biologist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA remained on cell phones --- even when no blood was involved. To find out, she and a colleague collectedflip-style phones from 10 volunteers. They collected invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user's ear. The scientists scrubbed(meaning "cleaned") the phones using a liquid mixture made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then the researchers collected the phones and repeated collecting traces on each phone once more. They discovered DNA that belonged to the phone's owner on each of the phones. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were cleaned. That suggests that washing won't remove all traces of evidence from a criminal's cell phone. So cell phones can now be added to the list of clues that can help a crime-scene investigation. Question: Which of the following is NOT mentioned in the passage? Yes or no, is the answer "The technique of collecting DNA on the phones."?

Ans:No

Ques:Article: YOU'VE lost your keys and your parents are both busy. If you had to ask one of them for help, whom would you pick? Before you give your answer, you should probably know that a new study found that women are better than men at multitasking , especially if one of those tasks is searching for a lost item. That should help you choose. In the study, a team of UK researchers compared the performances of 120women and 120men in a computer game involving tasks of counting and shape-recognition Men and women were equally capable when tasks were handled one at a time. But when the tasks started switching quickly , men responded c) much slower than women. To make the experiment more relevant to everyday life, researchers tried a second test. A group of women and men were asked to complete a series of "everyday challenges" such as finding restaurants on a map and searching for a lost key in a field. Once again, women outperformed men on the test, particularly in the key-searching task. "It suggests that- in a stressed and complex situation - women are more able to stop and think about what's going on in front of them,'' researcher Keith Law of the University of Hertfordshire, UK, told the BBC,[ln contrast,] men had a slight impulsiveness ;they jumped in too quickly" But where did women get the ability to keep organized under pressure? Researchers believe that it has its roots in evolution ,In early human communities, women had to keep an eye on children while cooking meals. Meanwhile, men only needed to focus on hunting. Men might not be happy about this study. After all, many great pilots are men and they have to deal with lots of information at the same time too. This is true, and researchers have their response. "[We don't mean]that all men can't multitask, or that only women can," said Laws.[We are saying that] the average woman is better able to organize her time and switch between tasks than the average man. There's no point denying these differences exist." Question: Which of the following is TRUE according to the article? Yes or no, is the answer "When the tasks started switching quickly in the test, the women in the study were more likely to take extra time to think."?

Ans:No

Ques:Article: Over the next 20 to 50 years, it will become harder to tell the difference between the human and the machine. All body parts will be replaceable. A computer will function like the human brain with the ability to recognize feelings and respond with emotions. They can then make fake people. We will then be able to create a machine duplicate of ourselves so we will appear to be alive long after we are dead. Maybe a few decades later, a way will be found to transfer our spirit to the new body. Then we can choose to live for as long as we want. Once one of you is duplicated, you will just have to press Ctrl + D and you will have two of you. If you want 500, select 500. Naturally, when duplicates are running around all over the place, there will be a food problem. The most practical choice would be garbage. Your modified duplicate will be made to eat garbage like a goat. But don't worry. Their taste buds and sense of smell will be changed so they will really enjoy it. They will want to eat lots of garbage. When it becomes possible to do a spirit transfer, you will be able to live within whichever duplicate you want, whenever you want and as long as you want. Just imagine what it would be like when you are with so many duplicates of yourself. You will be very busy enjoying many things. One duplicate of yourself is in the middle of doing a jigsaw puzzle and another duplicate has almost completed another puzzle. When you become tired of the joy of puzzles, "you" jump to the duplicate that is eating garbage, then to the one that is playing in a rock concert, then to the one that is scoring the winning goal. You will be so busy enjoying so many things that it could drive you crazy. When it is predicted that things will be better in the future, it doesn't necessarily mean that things will be easier! Question: Your duplicates will have to be modified in eating habits because they_. Yes or no, is the answer "need a large amount of food"?

Ans:No

Ques:Article: When I was 4, my parents decided they could no longer live together. That same year, my mom moved to Los Angeles (L.A.) and a therapist was hired to decide where I would live. Playing with a dollhouse in her office, I showed her the mother's room on one side and the father's room on the other. When she asked me about the little boy's room, I told her the little boy didn't know where to sleep. The therapist finally decided I would stay with my dad during the school years and visit my mom on long holidays and for summers. I began flying between two cities and leading two different lives. I remember my last school day in Grade Six. My friends made plans to go to the beach together, but I couldn't join them because I had to fly to L.A. It wasn't that I didn't want to see my mom and stepdad; I just didn't want to leave my friends. It wasn't easy to put up a wall, and pretend I didn't hate saying goodbye to them. In the morning, my dad drove me to school with my packed bags, and after school, my friends went together, and I went to the airport. What has come of this in the end is that I'm always missing somebody. When I'm in northern California, I miss my mom and stepdad, while in L.A. I miss going out with my friends, my dad, and my little brother and sister. But after so many flights, I've learned that it's also fun traveling between two cities and experiencing different lives. Other children may not have the opportunity to experience so much. Question: The dollhouse game showed that the boy _ . Yes or no, is the answer "had no feeling of belonging"?

Ans:
Yes
