Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: People who cannot tell all colors apart are said to be color-blind. Most color-blind people can see yellows and blues, but confuse reds with green. It is very rare for a person to be blind to all colors, but they may see everything in shades of black, white and gray. It is interesting to point out that many color-blind people don't even realize that they are color-blind, they don't know that the colors they are seeing and naming are not the actual colors that people with normal vision can see. This can be dangerous when a color-blind person confuses the red and green of a traffic light. Color blindness is thought to be inherited and although doctors have tested color blindness, there is no cure to treatment for it. Question: It's especially dangerous for a color-blind person to cross a street when _ Options: A: it is crowded B: it is a dark night C: there are no traffic lights at the cross of the streets D: the traffic light turns red
Ans: D

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: California, once regarded as a leader in the United States for its public higher education system, ranks next to the last in the U.S.for its number of adults with at least a high school diploma, according to the report, titled "California at the Edge of a Cliff," released by the California Faculty Association. Meanwhile, the state's investment in public higher education has dropped over the past three decades, and now ranks 22nd in the country.That's despite having the country's largest public higher education system, the report said. "It's a collapse ," said Thomas Mortenson, author of the report, who is an independent analyst living in Iowa and a senior scholar at the Pell Institute for the Study of Opportunity in Higher Education in Washington, D. C. "Ranking 49th out of 50 states is an indication that shows the quality of the state's educational has become much worse in recent decades." Mortenson said in the report.As of 2007, California ranked 14th in the United States in terms of college educated members of the workforce over 25 years of age, a drop from eighth place in 1981, the report showed. Mortenson said that California has never been the state of high status in education and economy while other states have made greater gains in building a college-educated workforce. The California Faculty Association is using the report's findings to criticize Governor Arnold Schwarzenegger's proposed funding cuts for education. Struggling with a 14.8-billion-dollar state budget deficit , Schwarzenegger has proposed a combination of sales tax increases, borrowing and major budget cuts, including cutting billions of dollars from the state's education budget. Question: The passage is mainly about _ . Options: A: California's worse situation in higher education B: the dangerous situation in California C: California's research on education and economy D: funding cuts for high education in California
Ans: A

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: In South America, the rich soil of the Amazon River basin in Brazil is known as "black gold". Scientists found that the secret of this rich soil was charcoal . Local people made it from animal bones and tree branches. They mixed the charcoal with the soil about 1.500 years ago. Now, scientists in the United States have done a modern demonstration. They say charcoal fertilization offers a revolutionary way to improve soil quality for hundreds or even thousands of years. Mingxin Guo and his team at Delavare State University heated tree leaves, corn stalks , small pieces of wood and poultry waste into "biochar" . They reported their findings at a recent meeting of the American Chemical Society in New Orleans. Biochar could be good news for farmers with poor soil and hungry populations to feed. Professor Guo says it could even help against global warming. Intensive farming and overuse of chemical fertilizer give out carbon dioxide into the atmosphere. Biochar does the opposite, he says. It traps carbon in the ground. The researchers planted winter wheat in containers of soil in a greenhouse -- some with biochar, some without. Professor Guo says the wheat grows much better in the pots with biochar. The soil was added two percent charcoal to. But he says even a one percent treatment will increase productivity. The results demonstrated that biochar can increase organic matter in soil. Loss of nutrients in soil is an increasing problem worldwide as farmers try to grow more food for growing populations. Next, the team will carry out a five-year study of biochar with spinach , green peppers and tomatoes. Mingxin Guo says he learns about the "black gold" in Brazil from a magazine story. He explains that it was discovered in the jungle, in the area where waters flow to the Amazon, in the 1960's. But it was not until recent years that scientists began to bring public attention to it. Question: Which of the following can be the best title of the passage? Options: A: Using Charcoal to Make soil into "Black Gold" B: Using Charcoal to Reduce the Carbon Dioxide C: How Amazon River Basin Produces "Golden Black" D: Guo's Research on Producing Biochar
Ans: A

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Almost 80% of the Americans have stated their opposition to cloning pet animals such as cats and dogs, yet companies still try to make a business out of selling cloned pets. Pet cloning has been promoted as a way to "bring back" or "copy" a beloved companion animal. However, studies have shown that cloning remains an experimental technology with many failures. Behind each lovely picture of a cloned cat or dog lie hundreds of animals that were kept in lab cages, receiving bad treatment to produce just that one cloned animal. For all that, you end up with a cloned animal who is unlikely to appear like the original physically or behaviorally and may experience serious health problems. Also, while pet cloning companies are charging customers up to $150,000 for a cloned pet, millions of homeless animals of the same species are available in US animal shelters for around $100. Unfortunately, most of these animals are killed for lack of adopting homes. With No Pet Cloning campaign, the American Anti-Vivisection Society (AAVS) tries to protect both animals and people from harm. They campaigned until the US companies that sold cloned animals closed their doors. First it was Genetic Savings & Clone Inc. and then it was BioArts International. When BioArts was closed, its owner, Lou Hawthorne, finally had to _ the problems of pet cloning. According to Hawthorne, he has seen numerous failures during his pet cloning attempts, "One clone----which was supposed to be black and white----was born greenish-yellow where it should have been white (we still have no good explanation for how that happened)." The AAVS is educating the public about the animal suffering and is seeking regulation of cloning activities. They will continue to take the lead in protecting animals from the threats of pet cloning. Question: According to the passage, companies keep on selling cloned pets to _ . Options: A: carry on scientific studies B: get economic interests C: protect pet animals D: comfort animal lovers
Ans:
B
