Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: (2013*,C)One day,when I was working as a psychologist in England,an adolescent boy showed up in my office.It was David.He kept walking up and down restlessly,his face pale,and his hands shaking slightly.His head teacher had referred him to me."This boy has lost his family,"he wrote."He is understandably very sad and refuses to talk to others,and I'm very worried about him.Can you help?" I looked at David and showed him to a chair.How could I help him? There are problems psychology doesn't have the answer to,and which no words can describe.Sometimes the best thing one can do is to listen openly and sympathetically. The first two times we met,David didn't say a word.He sat there,only looking up to look at the children's drawings on the wall behind me.I suggested we play a game of chess.He nodded.After that he played chess with me every Wednesday afternoon--in complete silence and without looking at me.It's not easy to cheat in chess,but I admit I made sure David won once or twice. Usually,he arrived earlier than agreed,took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down.It seemed as if he enjoyed my company.But why did he never look at me? "Perhaps he simply needs someone to share his pain with,"I thought."Perhaps he senses that I respect his suffering."Some months later,when we were playing chess,he looked up at me suddenly. "It's your turn,"he said. After that day,David started talking.He got friends in school and joined a bicycle club.He wrote to me a few times,about his biking with some friends,and about his plan to get into university.Now he had really started to live his own life. Maybe I gave David something.But I also learned that one--without any words--can reach out to another person.All it takes is a hug,a shoulder to cry on,a friendly touch,and an ear that listens. Question: What made David change? Options: A: His teacher's help. B: The author's friendship. C: His exchange of letters with the author. D: The author's silent communication with him.
Ans: D

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: The speed of light is often called a"constant ". New experiments show that may not be true, even within a vacuum. Sometimes, light slows a bit. The new research is"very impressive work", Robert Boyd toldScienceNews.An optical physicist at the University of Rochester in New York, he did not work on the study. He speaks of the new finding:"It's the sort of thing that's so obvious; you wonder why you didn't think of it first." Light travels as particles and as waves. Photons are the name given to those particles that represent the smallest possible amount of light. At their fastest, photons travel nearly 300 million meters (almost 1 billion feet) in a single second. That's fast enough to get to the moon and back in about 2.6 seconds. Scientists had long known, though, that they could slow light photons down by shining them through a material such as glass or water. Still, light moving through a vacuum has usually been assumed to move at a peak speed. That would seem to make sense. After all, a vacuum is a space with nothing in it to slow light down. In a new study, however, scientists show that even racing through a vacuum, light can slow. So the speed of light is more of a universal speed limit than an rule for how fast photons travel, the new data suggest. Miles Padgett led the new study. As an optical physicist, he works at the University of Glasgow in Scotland. He and his colleagues showed that the key to slowing light is to change the shape of a light wave. Padgett described how they did this in a paper published online January 22 inScience. His team raced a pair of photons. One traveled unchanged through a cable made from optical fibers. The other passed through a pair of devices that acted like lenses. A lens changes light: It can focus a spread-out beam of light on a point, for instance. The second photon passed through one device that changed the shape of its waveand another that changed it back to its original form. The first photon won the race. The second photon came in a tiny bit later, several... Question: The passage mainly tells . Options: A: light travels slowest through a lens B: light can be slowed down in a vacuum C: why the shape of a light wave can be changed D: what optical research looks like currently
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: The best family vacations are the ones where everyone is entertained and everyone gets along Not sure how to do that,especially if traveling with kids is involved?

They can also recommend which restaurants are the most family-friendly and take care of the reservations for you. Vacations for kids can be stressful enough (packing,keeping everyone entertained on the plane ride,finding kid--friendly foods, etc)without having the added worry of "what if something goes wrong?''A travel agent will take over if any accident occurs on your trip and will spend time calling companies and researching options until your problem is solved-whether that means you need to re-book a flight or find a trustworthy doctor for your child who has suddenly come down with an illness.

By taking the planning stress and trip organization off you and giving it to a travel agent, you'll be able to simply enjoy spending time with your family. Question: What is the text trying to persuade you to do? Options: A: To choose the travel destination from the travel agent B: To leave your kids behind when travelling C: To arrange your trip with the help of the travel agent. D: To stay home and spend more time with your family
