Do you love hamburgers? Do you how they were created? The first hamburgers in U.S. history were served in New Haven, Connecticut, at Louis' Lunch sandwich shop in 1895. Louis Lassen, founder of Louis' Lunch, ran a small lunch wagon selling steak sandwiches to local factory workers. Because he didn't like to waste the excess beef from his daily lunch rush, he ground it up, grilled it, and served it between two slice of bread--and thus America's first hamburger was created. The small _ is still owned and operated by the third and fourth generations of the Lassen family. Hamburgers are still the specialty of the house, where steak is ground fresh each day and hand molded, slow cooked, broiled vertically, and served between two slices of toast with your choice of only three "acceptable" garnishes: cheese, tomato, and onion. Want ketchup or mustard? Forget it. You will be told "no" in no uncertain terms. This is the home of the greatest hamburger in the world, claim the owners, who are perhaps best known for allowing their customers to have a burger the Lassen way or not at all. The best title of this article is  _  . A) The Creation of hamburgers B) Louis' Lunch C) A king of fast-food----Hamburgers D) Why People Love Hamburgers

A new study has found evidence of aggressive   behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children's behavior. The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day. Shakira Suglia, a famous expert, says they've found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression. "For the children who consume four or more soft drinks per day, we see more _ behaviors, which make them hard to get along well with others." The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people. The researchers have determined the link after considering factors like the child's age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home. Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons   and show signs of negative social behavior. After a further study on ingredients in soda, Shakira Suglia implies that the direct cause of the aggressive behaviors may be   _  . A) soft drinks B) attention problems C) caffeine D) social conditions

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk. Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma . They said that they found _ in studies that had reported associations between sunscreen use and higher risk of melanoma. Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence faster than any other cancer in the United States. But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning. The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--people with fair skin and freckles , for example--are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often. The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study. We can learn from the passage that  _  . A) sunscreen users get skin cancer more often B) the volunteers have proved the effect of sunscreen C) the new study was based on the experiences of volunteers D) the number of skin cancer patients is increasing in America

MADRID (Reuters)--Spain' s parliament   voiced its support on Wednesday for the rights of great apes   to life and freedom.     Parliament's environmental committee approved resolution   urging Spain to carry out the Great Ape Project (GAP), designed by scientists and philosophers who say our closest genetic  s deserve rights limited to humans.     "This is a historic day in the struggle for animal rights and in defense of our evolutionary comrades, which will doubtless go down in the history of humanity," said Pedro Poza, Spanish director of the Great Ape Project.     The new resolution has cross-party support and it is thought they will become law within a year, making Spain the first nation to extend legal rights to apes.     Under the new law, potential experiments on apes in Spain will be forbidden.     "We have no knowledge of great apes being used in experiments in Spain, but there is currently no law preventing that from happening," Poza said.     Keeping apes for circuses, television commercials or filming will also be forbidden.Housing apes in Spanish zoos, of which there are currently 315, will remain legal, but supporters of  _ have said the conditions in which most of them live will need to improve vastly.     Philosophers Peter Singer and Paola Cavalieri founded the Great Ape Project in 1993, arguing that "non-human hominids " should enjoy the rights to life and freedom and not to be mistreated. The Great Ape Project was probably set up to   _  . A) protect great apes' rights B) research the great ape society C) save the endangered great apes D) study the development of the great apes
