PROBLEM: Article: For new countries joining the European Union, and older ones getting used to their dark red passports, becoming "Europeans" is a bit like marrying into a large, eccentric family. Europeans have a lot in common but it is their differences, not their similarities, that attract the attention of sociologists and market researchers, and are more interesting. * 35% of Germans live alone, but only 9% of Spaniards. Perhaps this explains why Spaniards lead Europe in the habit of going out for a drink. * The British attend more adult evening classes than anyone else in Europe, and the Belgians least. So it can't just be the dark evenings. There are no figures on how many Britons go for a drink afterwards. If there were, they might be up at the top with Spain! * The British think black cats are lucky. Every other European country regards them unlucky. * The Dutch and Germans are the greatest caravaners , but the Germans like bigger beds in their caravans. * The French are the most athletic Europeans. Next come the Dutch. But the Belgians, just over the border, play fewest sports. * The Germans spend twice as much on heating as the Spaniards. Well, of course they do, it's colder. * Dutch husbands do the household shopping a lot more often than Italians or Spaniards. * The French are the champion public transport commuters of Europe. If you hate commuting, go and live in the Netherlands, where journeys to work are shorter than anywhere else. * The amount of direct eye-contact between strangers is three times greater among Spaniards than it is among the British or Swedes. Sharing a lift is torture for both the British and the Swedish. * No European countries really agree with any other about how to make good coffee. All of them are different. There are exceptions to all these rules. Deal with them in the spirit of my 8-year-old daughter. "If you don't understand each other's language, you just laugh a lot, and eat, and point at things."
Question: We can know from the passage that _ .
Options: (A) sociologists are most interested in the idea of the European Union (B) all the European countries are not willing to join the European Union (C) Europeans have a lot more differences than similarities (D) trade opportunities exist in the cultural differences in the European Union

SOLUTION: A

PROBLEM: Article: C.O.P.D blocks air flow through the lungs. It makes breathing difficult. The leading cause of C.O.P.D. is cigarette smoking. Experts at the National Institutes of Health in the United States say there is no cure to the damage to the lungs. Dawn Demeo is an assistant professor at Harvard Medical School in Boston, Massachusetts. She said, "By 2020, C.O.P.D. may be the third leading cause of death across the world." C.O.P.D. is a new name for emphysema and chronic bronchitis . These are the two most common forms of the disease. Many people with C.O.P.D. have both of them. And Doctor Demeo says more women than men now die from the disease. She is the lead author of a study by a team from Harvard's Brigham and Women's Hospital and the University of Bergen in Norway. The new study adds to findings that women may be more at risk than men from the damaging effects of smoking. The team examined results from a Norwegian study of 954 people with C.O.P.D. Inga-Cecilie Soerheim co-wrote the team's findings. Doctor Soerheim says they show that women suffered the same level of C.O.P.D.as men. But the female smokers were younger and had smoked a lot less. The team also looked at two groups among the people in the study. These were people under the age of 60 and those who had smoked for less than 20 years. In both cases, women had more serious C.O.P.D. and a greater loss of lung function than men.
Question: It can be known from the study that _ .
Options: (A) female smokers die faster than male ones. (B) women are more likely to suffer from the damaging effects of smoking than men. (C) O.P.D than women. (D) in the group of people under the age of 60, men suffered more from

SOLUTION: B

PROBLEM: Article: Every electronic gadget needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts. Now, scientists in California say they have come up with a way to turn a living cell into a memory device. It can store only one tiny bit of information, but it's a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease. Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can't be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream. If normal machines won't do the trick, perhaps biology will. Scientists who work in the field of synthetic biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information. This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive. In the new experiment, the researchers turned DNA from bacteria into a switch. They "flip " a small section of DNA. Then, using the same procedure , the scientists flip the section again--returning it into its normal structure. Using these DNA switches, "We can write and erase DNA in a living cell," bioengineer, Jerome Bonnet, explained to Science News. It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory--less than what a computer uses to remember a single letter. "This was an important proof that it was doable," Bonnet told Science News. "Now we want to build a more complex system, something that other people can use."
Question: What is possible future benefit of the cell-based gadget for people?
Options: (A) To detect disease at the earliest point. (B) To help improve the memory. (C) To help people build a body. (D) To replace many electronic gadgets.
