Q: Write a multi-choice question for the following article: Article: There are no exact differences between physics and other natural sciences because all sciences overlap .In general,however,physics is the scientific study of forces and qualities such as heat,light,sound,pressure,gravity and electricity,and the ways they affect other objects. One major branch of physics deals with the states of matter--solids,liquids and gases and with their motions.The pioneer achievements of Galileo,Kepler and Newton dealt with solid masses of matter in motion.Such studies deal with forces acting on moving objects.It is the subject of mechanics and belongs to the branch of mechanics called dynamics,the study of matter in motion.This large topic includes not only the motions of stars and ping-pong balls but also the motions of the water pumped by a fire engine and those of the air passing through the jet engine of an airplane. A branch of mechanics is statics ,the study of matter at rest.The designs of buildings and bridges are examples of problems in statics.Other branches of physics are based on the different kinds of energy,which interact with matter.They deal with electricity and magnetism ,heat,light,and sound.From these branches of physics scientists find clues which have revealed the constructions of atoms and how the atoms react to various kinds of energy. _ is often called the basis of modern physics.Among the many subdivisions of modern physics are electronics and nuclear physics.Physics is closely related to engineering.A person who uses knowledge of physics in solving everyday problems is often called an engineer.For example,electricity is one of the branches of physics;and an electrical engineer is a man who uses the "natural laws" of electricity to help in designing and electric generator .
A: Question: Among many branches of modern physics is _ .Options:A statesB electricityC electronicsD mechanicsAnswer:C

Question: Write a multi-choice question for the following article: Article: Wang Weiguo, an award-winning actor of the National Theatre Company of China, was wandering through Bejing's Panjiayuan Flea Market when he found a treasure, 20 exquisite picture frames . He bought them all. Inside the frames was a woman's life story. There were pictures of her as a baby and a growing child and pictures with her parents. Wang Weiguo was sure someone had lost them. He contacted the police and media. He showed them to friends and to people living outside China. No one recognized the people in the photographs. That was 1999. Wang never gave up the search. In 2010 he told the story to a TV host, Zhang Zequn, who suggested he contact China Radio International. Within three months of the story's being posted on CRI, someone recognized Julie Ege in one of the photographs. The wonderful Norwegian actress and model was the mother of the child whose growing years the photos traced. The child was Joanna Syson. She moved to Beijing in the 1990s to study Chinese. In 1999 she returned to Norway for six months, entrusting all her belongings, including the photographs, to a friend. When she returned, the friend was gone. So were her belongings. She was heartbroken. More than a decade passed. Then, thanks to the story posted on CRI and to a visitor to the website, the trail finally led to Joanna Syson. She traveled to Bejing to meet Wang Weiguo, who had searched for her for 12 years, and to recover her treasured photographs.
Answer: Question: What is the best title of the text?Options:A Flea market treasure finds its way homeB A touching story happening in a flea marketC A wonderful and honest Chinese actorD A sad story about a girlAnswer:A

Question: Write a multi-choice question for the following article: Article: Close relationships, thought to help communication by giving speakers a common context, are actually more likely to make _ when strangers are involved, a new study suggests. Because close colleagues and friends already share so much common knowledge that they often use short, ambiguous messages which can lead to misunderstandings. "People are so used to talking with those with whom they already share a great deal of information that, when they have something really new to share, they often present it in a way that they assume the person already knows it." says study-team member Boaz Keysar. Keysar and his graduate student, Shall Wu, trained 40 pairs of undergraduate students to memorize made-up names and descriptions of strange shapes. In each pair, the "director" had to communicate the identity of one of the 24 shapes. The partner had to use the information to choose the correct shape from a set of three images on a computer monitor. Half of the partners studied only the first six shapes, while the others learned the first 18 shapes. The directors, who had memorized all the shapes, were aware of their partners' knowledge levels of the shapes. In the pairs with the most shared knowledge, the directors were more likely to rattle off shape names, compared with pairs with little knowledge overlap , in which the directors were more likely to describe the actual shapes. Not surprisingly, participants with more shared knowledge were twice as likely to ask for clarification as those with less overlap. Language itself can be confusing. "The reason all this is happening at all is that language in general is ambiguous," said Keysar. He recalls an ambiguous billboard near a stadium holding a Rolling Stones concert that night. The billboard read, "Avoid LSD tonight." (:LSD"") Hmmm? "It was about Lake Shore Drive, and I'm sure the writer of the sign didn't realize he was being ambiguous," Keysar said. "Even though miscommunication can lead to missed meetings or deadlines, people are often unaware when their language is...
