I'm taking a test and have to guess the right answer to the question after the article. Article: Jeans are trousers made of a kind of clothe called denim. For many people, blue jeans represent American culture. The history of blue jeans usually begins with a man named Levi Strauss. Although he did not invent the jeans, he is considered the first person to produce and sell this kind of clothing in large amounts. Levi Strauss was born in Bavaria, Germany. In 1847, he and his family moved to the US. He opened a store, first in New York, and then in San Francisco, California. Among the products he sold were jeans. These trousers were especially useful for miners in California who needed clothing made of a strong material. Levi Strauss partnered with a clothing maker named Jacob Davis, who had invented a process for making rivets for jeans. These metal things helped strengthen the blue jean cloth to make the trousers stronger. In 1873, Strauss and Davis received a patent to officially own this invention. They began producing " copper-riveted waist overalls ". In 1928 the Levi Strauss company used the word "Levi's" as the trademark for their products. The 19th-century workers would probably be surprised to know that their trousers would one day become a fashion object. Today, jeans are worn by people of all ages, incomes and lifestyles. Jeans come in many colors other than blue and in many styles and at many prices. A national museum in Washington, D.C. has one of the oldest known pairs of Levi's jeans in its collection. Jeans have come to express different ideas about American culture based on the people who wear them. These include the heroes of the Wild West and famous Hollywood actors like James Dean and Marlon Brando in the 1950s. Writer James Sullivan published a book called Jean: A Cultural History of an American Icon. In the book, he says jeans serve as a sign for two American values, creativity and rebellion . Question: We know from the passage that Levi Strauss _ . Options: A: was the first person who wore jeans. B: moved to the US from Germany alone. C: not only sold jeans at first in his store D: helped Jacob Davis invent a kind of rivet

I'm taking a test and have to guess the right answer to the question after the article. Article: Never Talk to Strangers? "Never talk to strangers." Many children are taught this simple rule as a precaution against abduction . In June, 2005, an 11-year-old boy was lost in the Utah wilderness for four days. During that time, he stayed on the path. He saw people searching for him but deliberately hid from them, afraid someone might "steal" him. Eventually, the unfortunate game of hide-and-seek ended and he was found. According to the Canada Safety Council, this alarming incident shows how unwise it is to instill a fear of strangers in children. The "stranger danger" message can prevent children from developing the social skills and judgment needed to deal effectively with real-life situations. In a difficult situation, a stranger could be their lifeline to safety. To have a child go missing is a parent's worst nightmare. The threat of abduction by a stranger is minimal when compared with other possible reasons for a disappearance. In 2004, there were 67,266 missing-children cases in Canada. Only 31 involved abduction; in most of those cases the abductor was a relative, friend, or person known to the family. There were 671 cases of children wandering off, and 332 cases of abductions by a parent. Almost 80 percent of all cases were runaways. These statistics cast doubt on the idea that children should never talk to strangers. Wandering off is more common--but a lost children may have to call upon a stranger for help, and must develop the ability to judge what kind of people to approach. The "never talk to strangers" rule does not protect children in the situations they are most likely to face. On top of this, it can be confusing. Adults do not model the behaviour; they often talk to strangers. A child may not know how to tell who is a stranger, and who is not. For young children, nothing replaces close supervision . Pre-schoolers do not understand risk and tend to act without thinking. Children need to develop habits and sttitudes that will protect them from the real threats and dangers they may face. The... Question: Which would the author agree with about the "never talk to strangers" rule? Options: A: It is not well recognized by parents. B: It is not effective in keeping kids safe. C: It is easy enough for children to follow. D: It is practical as a safety tip in daily life.
