Read the following article and select the best answer. Article: When going through major life changes, like changing careers, I would change the people with whom I spent the most time. We've all gone through periods when the people in our lives have changed--graduation, moving to a new city, getting a new job, joining a new club, etc. I don't think I need to convince you just how much influence other people can have over your identity. If you've ever experienced a major switch in your people environment, then you know that you change as well. Most people don't make these choices consciously, though. You might consciously decide to spend more time with a certain friend, or you may ask someone out on a date to begin a new relationship. But few people choose their existing friendships deliberately. _ . People are always dropping into and out of each other's lives. Associations grow into friendships, and friendships fade into associations. You don't get rid of anyone. The truth is that in order to make room for new people and new experiences, you may need to loosen up some of your existing connections. What about loyalty? Shouldn't you always be loyal to your friends? Once you have a close friend, even if his influence on you is slightly harmful, shouldn't you stick by him? Loyalty to a friend sometimes means having to let go. It means being loyal to his highest and best self as well. If someone is destroying his health by smoking, for example, you aren't showing loyalty by smoking right along with him. True loyalty sometimes requires that you break damaging connections, get yourself back on solid ground, and then decide what you can really do to help your friend. It can take a lot of courage to tell someone, "I'm sorry, but I can't have you in my life anymore." But even though this might seem like a selfish act at times, it's often the best thing for the other person, too. If a relationship is holding you back in some way, understand that it's also hurting the other person. For example, if you work for a violent boss, your acceptance of that situation is considered to be... Question: When experiencing major life changes, people may _ . - join a new social community - influence their friend around - choose their friendships purposely - have their people environment changed
have their people environment changed

(Question)
Read the following article and select the best answer. Article: Nearly everyone agrees that money doesn't buy as much as it used to, no matter when you want to spend it. This is certainly true of the paper money that passes so quickly through one's hands. But what about coins that seem to do very little except stay in purses and pockets? Unlike notes, metal money becomes more valuable the longer it is held, especially if it is put away where it won't get scratched or worn. Why is this? One reason is that coins, being more durable, fall more readily into a category for collectors. Naturally, the rarer gold pieces must become more valuable as the price of this metal goes up. But, curiously, one of the rarest coins in the world is not made of gold, but of the relatively cheaper silver. In 1840, the United States mint struck 19570 silver dollars. That is what its records show. Today only six of this original number remain and these are unlikely ever to reach the auction market. So what happened to some 19564 large silver coins, not the easiest sort of things to lose? One of the more romantic theories is that they were part of the payment to Napoleon for the American land then known as Louisiana. But they never reached France. Somewhere in the Gulf of Mexico, the ship transporting them was sunk, either by a storm or by pirates. The probable answer to the mystery is that they were melted down -- since the silver value was greater than the actual value of the coin. What really happened to the rest will probably always remain a mystery. What is known is that whoever can come up with one will find himself instantly rich. Question: Which of the following is true of a coin? - The longer it is held, the less valuable it becomes. - The more it wears out, the more valuable it becomes. - The less it gets scratched, the less it values. - The longer it lasts, the more it values.
(Answer)
The longer it lasts, the more it values.

Ques:Read the following article and select the best answer. Article: Learning a second language can improve brain power, scientists believe. US researchers from Northwestern University say bilingualism is a form of brain training -- a mental "work out" that adjusts the mind finely. Speaking two languages well affects the brain and changes how the nervous system reacts to sound, lab tests showed. Experts say the experiment performed by the National Academy of Sciences provides "biological" evidence of this. In an attempt to prove the guess that speaking two languages is good for one's mind, the team monitored how the brain of 48 healthy student volunteers reacted to different sounds. Twenty three of these volunteers were bilingual. The scientists used special equipment to trace the pattern of brainwaves. Under quiet, laboratory conditions, the bilingual students responded in a similar way to the English-only-speaking students, who formed the control group. But the bilingual group were far superior at processing sounds even when there were a lot of people talking in the room. They were better able to focus on to the important information -- the speaker's voice -- and block out other _ noises. Prof Nina Kraus, who led the research, said: "The bilingual's better experience with sound results in a hearing system that is highly efficient, flexible and focused in its automatic sound processing, especially in challenging or novel listening conditions." Co-author Viorica Marian said: "People do crossword puzzles and other activities to keep their minds sharp. But the advantages we've discovered in double language speakers come automatically simply from knowing and using two languages.'' Musicians appear to gain a similar benefit when rehearsing , say the researchers. According to some theories, being bilingual might help avoid dementia . Question: What does Viorica Marian seem to believe? - People should do crossword puzzles to keep their minds sharp. - Bilingual students have more advantages in study than non-bilingual ones. - Speaking two languages is an easier way for people to increase their brain power. - Bilingual students are better at solving crossword puzzles.

Ans:
Speaking two languages is an easier way for people to increase their brain power.
