Read the following article and select the best answer. Article: Each year, bad food sickens about one in six Americans. Proposed new rules aim to improve food safety. Officials say the changes could prevent more than one million cases of food-related illnesses each year. The new rules were proposed this month, exactly two years after President Obama signed the Food Safety Modernization Act. The rules are the first step in putting the law into effect, making the biggest changes in food safety since the 1930s. The law makes the Food and Drug Administration responsible for preventing food-related illnesses. Experts say this is a change from the role that the FDA has played in the past in reacting to disease outbreaks . Congress passed the law after a series of outbreaks linked to bagged spinach, peanut butter and other foods. Margaret Hamburg is commissioner of the FDA. "They occurred because of problems that would have been solved by these kinds of approaches. So I think, you know>> we're very optimistic that we will begin to see the real change. " The agency is proposing to require food manufacturers to show that they have identified where contamination is most likely to happen. Manufacturers would also have to show that they have taken steps to prevent it. The proposed rules also deal with safety in growing and harvesting fruits and vegetables. Caroline Smith DeWaal is director for food safety at the Center for Science in the Public Interest. She says the rules should have been released a year ago. And she notes, "The bigger question is, where are the rules on imports that haven't been released yet?" The FDA says about 15 percent of food eaten by Americans is imported, and that share is growing. Rules have not been released yet to require imported foods to meet the same standards as food produced in the United States. Question: The new rules require the Food and Drug Administration to _ . - be responsible for Americans' safety - take stricter measures - improve its work efficiency - change its role
change its role

Read the following article and select the best answer. Article: Modern inventions have speeded up people's lives amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster each new computer boasts of saving precious seconds in handling tasks. All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so. We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind in another time zone. Again, spending too long at computers results in painful wrists and fingers. Mobile phones also have then danger according to some scientists; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about. However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imaginations take us into another world. There was a time when some people's lives were devoted simply to the cultivation of the land or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestors faced; they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modern machinery has freed people from that primitive existence. Question: What does the passage mainly discuss? - The present and past times - Machinery and human beings - Imaginations and inventions - Modern technology and its influence
(Answer)
Modern technology and its influence

Ques: Read the following article and select the best answer. Article: While every dog owner knows their dogs can read their moods perfectly, scientists have always been a piffle doubtful.Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria; we finally have some convincing evidence. For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy.Half the dogs were rewired for touching the screen when shove a happy face, while the other half gilt their treat for selecting those that appeared angry. Interestingly, the dogs were not provided with the entire face.Some dogs were show Ti only upper halves while the others observed lower halves.That's because the scientists believe humans show their eruptions on their equities face. After some training ill.e how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face, the researchers concluded the dogs were smart-enough to read human emotions. They also found those being trained to read angry expressions took a longer time to learn.They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly.However, once the smart dogs realized they were getting rewired, the trepidation seem end to disappear.In fact, the dogs had such a good time playing the computer "game" That scientists had a hard time keeping them away from the touch screens after the study was completed. The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly.Since the touches careen models were all females, this confirmed what has been observed in previous studies-dogs are more efficient at reading facial expressions of people that are the serene gender as their owner. Question: Which of the following statements is TRUE? - The dogs were not all provided with the entire face, - According to their size, the dogs were given either upper or lower halves. - The dogs could read even small changes that accountancy facial expressions after some training. - The dogs couldn't read strangers facial emotions.
