Read the following article and select the best answer. Article: Wilma Subra had no intention of becoming a public speaker. After graduating from college with degrees in chemistry and microbiology, she went to work at Gulf South Research Institute in Louisiana. As part of her job, she conducted field research on toxic (poisonous) substances in the environment, often in minority communities located near large industrial polluters. She found many families were being exposed to high, sometimes deadly levels of chemicals and other toxic substances. But she was not allowed to make her information public. Frustrated by these restrictions, Subra left her job in 1981, created her own company and has devoted the past two decades to helping people fight back against giant industrial polluters. She works with families and community groups to conduct environmental tests, interpret test results, and organize for change. Because of her efforts, dozens of toxic sites across the country have been cleaned up. And one chemical industry spokesperson calls her "a _ top _ gun" for the environmental movement. How has Subra achieved all this? Partly through her scientific training.Partly through her commitment to environmental justice. But just as important is her ability to communicate with people through public speaking. "Public speaking," she says, "is the primary vehicle I use for reaching people." If you had asked Subra before 1981 "Do you see yourself as a major public speaker?", she would have laughed at the idea. Yet today she gives more than one hundred presentations a year. Along the way, she's lectured at Harvard, testified before Congress, and addressed audiences in 40 states, as well as in Mexico, Canada, and Japan. Question: What did Wilma Subra study for her job before 1981? - Chemistry and microbiology. - Families affected by toxic chemicals. - Toxic substances in the environment. - Minority communities near industrial polluters.
**Answer**
Toxic substances in the environment.

Read the following article and select the best answer. Article: There is no place like home--as long as it is far enough away, it seems. Britain has become a nation of nomads ,with nearly half of us living more than 100 miles from the town or village where we grew up, research shows. The trend is being fuelled by the Internet, better communications and property wealth. People who move away fit into four separate categories--Sheep, Hens, Cows or Pigs. Sheep are people who change home for economic and emotional peace. Hens are home and environment care-seekers. Cows are career or work shifters, while pigs are people caught up in grand parental support. It is far from the common believed idea of Coronation Streets, where close-knit generations of the same family live within a few streets of each other throughout their lives. Less. Than 20 percent of people now live in the town where they were born. Instead, young adults move away to find work, get married or seek adventure. Many use the Internet to work from a home which need not be within easy traveling distance of their workplace. Also joining the moving crowd are older people who either move to be near grandchildren or retire to new homes. One in ten of those who do make away makes a complete break, and now lives 500 miles or more from where they grew up. Women are likely to leave as men, a sign of independence that would not have excited in the 1950s and 60s. People in the North-East, North-West, Yorkshire and prefix = st1 /Scotlandare the most likely to live in the community where they were born, the study found. Question: Which of the following is not a reason for the trend mentioned in the text? _ . - The wide use of Internet - Improved communications - People becoming richer - More job opportunities
**Answer**
More job opportunities

Read the following article and select the best answer. Article: "You know, Chihuahuas aren't actual dogs. They're a kind of fox," announced a woman at a party. This woman entirely believed that Chihuahuas are the descendants of the Fennec fox. Many people might believe this: Chihuahuas are similar to foxes in their appearance with long-haired Chihuahuas appearing almost indistinguishable from their wild counterparts . The idea that Chihuahuas are related to foxes isn't uncommon. Even the American Kennel Club, which is usually a highly respected source of information, accepts the belief and the similarity between Chihuahuas and Fennec foxes. Interesting as it is to imagine that Chihuahuas are a breed of the fox, this idea simply can't hold water. Chihuahuas are, in fact, far more closely related to dingoes or wolves than they are to Fennec foxes. Like other dogs, Chihuahuas are able to breed with other members within the same species. The Fennec fox is a member of a different species. Chihuahuas and Fennec foxes are fairly distantly related just like a cat and a tiger are. Their similarities occur only because of a phenomenon known as convergent evolution , in which animals develop similar features to meet similar biological needs. A simple observation of geography further denies the idea that Fennec foxes and Chihuahuas are related. While the Fennec fox was living in the deserts of Africa, the Chihuahua came from Mexico, where it got its common name. Its closest living s are other native Central and South American breeds. Its ancestor, the now nearly-extinct Mexican gray wolf, is also a much closer to the Chihuahua than any other fox. It is common to consider the cute Chihuahua as a little Fennec fox adapted to life, but this theory is not true. Chihuahuas are domestic dogs to the same degree as other dogs. Much as a Chihuahua might look like a fox, it is--and always will be--a dog. Question: Why did the woman say Chihuahuas are a kind of fox? - They are a breed of the special fox. - They partly have the features of foxes in appearance. - Their ancestor is the Fennec fox in fact. - Their habits are just like those of foxes.
**Answer**
They partly have the features of foxes in appearance.
