Ques: Read the article and select the best answer. Article: Newborns begin to develop language skills long before they begin speaking. And, compared to adults, they develop these skills more quickly. People have a hard time learning new languages as they grow older, but babies have the ability to learn any language easily. For a long time, scientists have tried to explain how such young children can learn the complicated grammatical rules and sounds of a language. Now, researchers are getting a better idea of what's happening in the brains of the tiniest language learners. This new information might help kids with learning problems as well as adults who want to learn new languages. It might even help scientists who are trying to design computers that can communicate like people do. Most babies go "ma ma" by 6 months of age, and most children speak in full sentences by age 3. For many years, scientists have wondered how the brains of young children figure out how to communicate using language. With help from new technologies, scientists are now finding that babies begin life with the ability to learn any language. They get into contact with other people, listen to what they say and watch their movements very closely. That is why they quickly master the languages they hear most often. Studies show that, up to about 6 months of age, babies can recognize all the sounds that make up all the languages in the world. Starting at around 6 months old a baby's brain focuses on the most common sounds it hears. Then, children begin responding only to the sounds of the language they hear the most. In a similar way older babies start recognizing the patterns that make up the rules of their native language. For example, English children who are about 18 months old start to figure out that words ending in "-ing" or "-ed" are usually verbs, and that verbs are action words. Question: The researchers found out that babies learn a language mainly by _ . Options: A: repeating the words of other people B: remembering the full sentences they hear C: hearing and closely watching others speak D: figuring out the meaning of different sounds
Ans: C

Ques: Read the article and select the best answer. Article: The koala is one of Australia's most treasured creatures, which is a lovely little creature. But now, it is in big trouble. Affected by habitat loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population, that is worrying many scientists about the fate of the koala. The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food. Treating Chlamydia in wild koalas is a challenge. There is no treatment available for _ . Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala;it is up to each region to make management plans for its koala population. The good news is that researchers are working to test a vaccine that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccil1e more widely. But it's impossible to vaccinate all wild koalas. Another possibility would be to make vaccine distribution a routi11e part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs. While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may buy enough time to give researchers a chance to solve some of the other problems facing Australia's koalas. Question: Which isn't considered the main cause of koala's population decline? Options: A: Habitat loss. B: Injuries from cars and dogs. C: Climate change. D: A deadly disease.
Ans: B

Ques: Read the article and select the best answer. Article: I dropped out of Reed College after the first 6 months, but then stayed around as a drop-in for another l8 months or so before I really quit. So why did I drop out? It started before I was born. My biological mother was a young, unmarried college graduate student, and she decided to, put me up for adoption. She felt very strongly that I should be adopted by college graduates, so everything was all set for me to be adopted at birth by a lawyer and his wife. Except that when I popped out they decided at the last minute that they really wanted a girl. So my parents, who were on a waiting list, got a call in the middle of the night asking: "We have an unexpected baby boy; do you want him?" They said: "Of course. " My biological mother later found out that my mother had never graduated from college and that my father had never graduated from high school. She refused to sign the final adoption papers, She only gave in a few months later when my parents promised that would someday go to college. And 17 years later I did go to college. But I artlessly chose a college that was almost as expensive as Stanford, and ail of my working class parents' savings were being spent on my college tuition. After six months, I couldn't see the value in it. I had no idea what I wanted to do with my life and no idea how college was going to help me figure it out. And here I was spending all of the money my parents had saved their entire life. So I decided to drop out and trust that it would all work out OK. It was pretty scary at the time, but looking back it was one of the best decisions I ever made. The minute I dropped out I could stop taking the required classes that didn't interest me, and begin dropping in on the ones that looked interesting. It wasn't all romantic. I didn't have a dorm room, so I slept on the floor in friends' rooms, I returned coke bottles for the $ 5 deposits to buy food with, and I would walk the 7 miles across town every Sunday night to get one good meal a week at the Hare Krishna temple. I loved it.... Question: The author dropped out mainly because _ . Options: A: His academic performance was very poor. B: He did not want to waste his parents' money. C: His parents were too poor to afford the college tuition. D: He didn't think university could help him to get a well-paid job
