Ques: Read the article and select the best answer. Article: With a wildlife guide, I stepped on a journey to find one of the rarest creatures in the world ----the spirit bear, a walking contradiction--a white black bear. Neither albino nor polar bear, the spirit bear is a white variant of the North American black bear, and it's found almost exclusively here in the Great Bear Rainforest. At 25,000 square miles ---- one and a half times as big as Switzerland--the region is a spooky , wild, mysterious place: there are wolves here that fish. Deer that swim. Western red cedar trees that have stood a thousand years. And a black bear that is white. Scientists know how black bears are born white. They're just not sure why. The phenomenon, known as Kermodism, is caused by a recessive mutation at the MC1R gene, the same gene associated with red hair and fair skin in humans. To be born white, a bear must inherit the mutation from both parents. The parents themselves don't have to be white. They just need to carry the recessive mutation. So it's not uncommon for white bears to be born to black parents. White fur happens in only one of every 40 to 100 black bears on the British Columbia mainland coast, but the feature is especially distinct on certain islands in the Great Bear Rainforest. For example, on Princess Royal Island, one in ten black bears is white, and on Gribbell Island, directly north of Princess Royal, it's one in three. It's unclear how the feature arose. One theory was the "glacial bear" hypothesis that the spirit bear represented a remaining adaptation from the last great ice age, which ended here 11,000 years ago. At that time most of modern-day British Columbia was still icebound, and a white coat may have offered camouflage . But the "glacial bear" theory raised a question: Why didn't the white fur feature die out when the glaciers _ ? Researchers have recently proved that the spirit bear's white coat gives it an advantage when fishing. Although white and black bears tend to have the same success rate after dark, there is a difference during the... Question: It is most likely that white fur happens _ . Options: A: on Princess Royal Island B: on Gribbell Island C: on the British Columbia mainland coast D: on islands in the Great Bear Rainforest
Ans: B

Ques: Read the article and select the best answer. Article: More than 40 years ago, John Williams gave away all of his belongings and went off to the mountains to live the way people lived 100 years ago. For food he traps wild animals, fishes in the rivers, and plants whatever he can. John lives in a cabin he made by hand, out of trees he chopped down with an ax. Though he has no s he knows of, he does have a deer he raised from a fawn. The deer lives in the house in the winter and goes with John when he goes into the forest for food. Nobody lives within fifty miles of his cabin in the mountains and John has not been out of the mountains during the entire forty years. One day last year I hiked in to see how John lives. It was like going back in time. There were no roads, no stores, no noise, no pollution, not even a post office. Most notable of all, there were no people and that's just the way John Williams wants to keep his part of the world--without people. But there is a paradox in his story. John is an educated man. He has books and nobody knows how he got them. Mostly he reads about his world, the forest, the animals, the plants, and the mountains. He has seen airplanes flying overhead but does not want to know about them. For him, electricity is lightning, not light bulbs, refrigerators, televisions, or washing machines. John Williams is 85 years old and had not had a sick day in his life. He attributes his long life to the fact that it has nothing to do with people and in order that he might enjoy many more years of health, happiness, and solitude, I will not tell you where his kingdom lies. There is no room there for you or me. Question: Who lives in John Williams' house? Options: A: He and his family. B: John Williams himself. C: Nobody--he sleeps outside. D: A group of friends.
Ans: B

Ques: Read the article and select the best answer. Article: Dear Editor; Why do newspapers carry so many advertisements for electronic equipment? Last Sunday I counted ads for seven kinds of televisions and thirteen kinds of radios in the Atlanta Journal. Besides that, there were pages and pages of ads for Citizens' Band radios and tape recorders. Don't you realize what electronic equipment is doing to our daily life? Everywhere you go you may hear loud musician advertisements over radios; this continual noise is ruining our ears. Husbands don't talk to wives any more; they are always watching the news or a ball game. Children ruin their eyes (not to mention their minds) with endless hours of watching not only the programs for children but those for grown-ups as well. And worse, hidden microphones find out about our private lives, and computers keep records of personal information about us. Enough is enough! I think you should limit the amount of advertising of electronic equipment in the Atlanta journal. Otherwise it will make life unbearable for us all. Question: Electronic equipment causes all the following problems except that _ . Options: A: personal information is given to strangers. B: Children ruin their eyes. C: News of the world is given to all citizens D: Family members don't talk to each other
Ans:
C
