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 . Question: Among many branches of modern physics is _ . Yes or no, is the answer "electronics"?
(Answer)
No

Article: Richard Wagner was a German musician has been a very controversial person, but he has gained great fame by writing opera, a form of performance combining singing, music on instruments, and drama. While he wrote excellent music, many people think his operas are too dark and serious, lacking the fun common in operas written before his time. Wagner, on the other hand, thought the opera of his time was too simple.He wanted to make opera a serious form of art that combined drama and music to tell deep stories that would have a strong effect on the audience. Some people thought Wagner's new kind of music was too different from the operas they were used to hearing.Wagner agreed with them.In fact, he didn't call his works "operas" at all, using instead a German word that means "Musical Festival" or "Musical play". While many people today still do not like Wagner's operas, they cannot deny that Wagner has had a lot of influence on opera as a form of art.Wagner invented the tradition of turning off the lights before starting a play.He also was the first person to make the whole audience sit down for an entire play.Today, almost all operas are performed in this manner. Wagner as a man was even more controversial than Wagner as a writer of music.He hated Jewish people, and made many people angry, which we would today think of as evil.Some would say he was a good musician, while others would say that he was a bad musician.But it would be difficult to say he was not an important person in music and in the world. Question: Which of the following best expresses the main idea of the passage? Yes or no, is the answer "Richard Wagner is a very controversial man."?
(Answer)
No

Article: A Japanese company has ordered its employees to get the same hairstyles--- to help save energy. Tokyo-based Maeda Corporation has announced the move as part of a national campaingn to cut energy use. Since Fukushima nuclear plant was destroyed in the earthquake and tsunami that struck Japan in March, 2011, the county's government has asked its people to _ their energy consumption. Men are expected to sport a short back-and-sides, slightly longer on the top, while women have been asked to wear short hair with a fringer that can be swept to one side. Chizuru Inoue, a spokesman for Maeda Crop, said: "Our company is very devoted to protecting the environment and we encourage our staff to adopt many environment-friendly actions." "We are not sure of the data yet, but we believe if people have short hair they do not need to use their hairdryers for so long and they will use less water. If all our staff do this, then it may save a lot of power." There is another advantage for employees of the construction firm, Ms. Inoue added, as it is easier to make short hair neat again after staff had been wearing hard hats. She said a lot of staff had been calling for information on where they can get their hair cut in the correct style. Following the Fukushima nuclear disaster in March, Japan has been struggling to produce enough electricity for the tsunami ended production at the Fukushima plant. The disaster resulted in a review of the country's energy policy that now means less than a quarter of its remaining nuclear plants are in use. The government has talked about a move away from nuclear energy towards more sustainable technologies. Many government institutions have taken measures to save power, including a reduced use of air-conditioning in offices and schools. Question: What's the main idea of the text? Yes or no, is the answer "A Japanese company takes measures to save energy."?
(Answer)
No
