Article: Life has changed in Mexico City. Streets normally filled with people are empty. One of the most popular professional soccer teams recently played a game in an empty stadium that can seat more than100,000 people. It's swine flu that has made life in Mexico City grind to a halt . Seemingly out of nowhere, swine flu has caused confirmed deaths in 12 countries as of April 30. It has sent a wave of alarm around the world. Governments are trying to find ways to prevent further out-breaks. The World Health Organization has raised its swine flu global threat level to five out of six. People may be familiar with bird flu, but they know little about swine flu. Swine flu is a contagious respiratory disease in pigs. It is caused by a type-A influenza virus. Humans can also catch swine flu. The virus causes regular outbreaks in pigs, but people usually do not catch it. However, there have been cases of the virus spreading to people, and then from one person to another. The symptoms of swine flu are similar to the common flu. They include fever, lethargy , lack of appetite, coughing, runny nose, sore throat, nausea , and vomiting . The high proportion of young adults among the deaths is one of several mysteries about this virus. Most of the dead had lung damage. What caused it is not yet known. The virus spreads the same way the common flu does. When an infected person coughs or sneezes around another person, the latter is put at risk. People can get the disease by touching something with the flu virus on it and then touching their mouth, nose or eyes. There are medicines to treat swine flu. Doctors suggest using anti - viral drugs. They keep the virus from reproducing inside the body. Although there are no vaccines for it now, several everyday steps can help prevent the spread of the virus: washing hands frequently; avoiding close contact with people who are sick; and avoiding touching surfaces that might have the virus on it. People may worry that they will get swine flu from eating or preparing pork. In fact,... Question: What can we infer from the passage? Yes or no, is the answer "At present there still aren't effective vaccines for swine flu."?
No

Article: Bobby Moresco grew up in New York's Hell's Kitchen, a poor working-class neighborhood on Manhattan's West Side. But Hell's Kitchen lies right next door to Broadway, and the bright lights attracted Bobby from the time he was a teen. Being stage-struck was hardly what a street kid could admit to his partners. Fearing their making fun of him, he told no one, not even his girlfriend, when he started taking acting lessons at age 17. If you were a kid from the neighborhood, you became a cop, construction worker, longshoreman or criminal. Not an actor. Moresco struggled to make that long walk a few blocks east. He studied acting, turned out for all the cattle calls -- and during the decade of the 1970s made a total of $2,000. "I wasn't a good actor, but I had a driving need to do something different with my life," he says. He moved to Hollywood, where he drove a cab and worked as a waiter. " My father said, 'Stop this craziness and get a job; you have a wife and daughter.' "But Moresco kept working at his chosen career. Then in 1983 his younger brother Thomas was murdered in a killing. Moresco moved back to his old neighborhood and started writing as a way to explore the pain of Hell's Kitchen. Half-Deserted Streets, based on his brother's killing, opened at a small Off-Broadway theater in 1988. A Hollywood producer saw it and asked him to work on a screenplay. His reputation grew, and he got enough assignments to move back to Hollywood. By 2003, he was again out of work and out of cash when he got a call from Paul Haggis, a director who had befriended him. Haggis wanted help writing a film about the country after September 11. The two worked on the writing Crash, but every studio in town turned it down. They kept trying. Studio executives, however, thought no one wanted to see hard lives in modern America. Crash slipped into the theaters in May 2005, and quietly became both a hit and a critical success. It was nominated for six Academy Awards and won three -- Best Picture, Best Film Editing and Best Writing... Question: Which of the following can best describe Bobby Moresco? Yes or no, is the answer "ambitious and persistent"?
No
