Question:
Light rays strike a reflecting surface. They are then reflected back. You can predict the angle of the reflected light. Imagine a ball bouncing off a surface. Light can do the same thing. That is, assuming the surface is shiny. So how do you know where light will go after it strikes a shiny surface? It depends on how the light initially strikes the shiny object. Light does not always go straight toward a surface. Therefore, not all light bounces straight back. Sometimes, light can hit a surface at an angle. The angle at which it strikes the surface tells us how it will bounce off. While light is different to a ball, they react in a similar manner. Many sports rely on knowledge of reflection. Pool players know a lot about reflection. They take great care when they strike the pool ball. They need it to go to a certain place. They know the angle it will hit the side of the pool table. After reading the above, is "The angle at which it strikes the surface." the correct answer to the question "What determines how a ball will bounce off a surface?"?

Answer:
yes

Question:
This is the story of a young girl and her dog. The young girl and her dog set out a trip into the woods one day. Upon entering the woods the girl and her dog found that the woods were dark and cold. The girl was a little scared and was thinking of turning back, but yet they went on. The girl's dog was acting very interested in what was in the bushes up ahead. To both the girl and the dog's surprise, there was a small brown bear resting in the bushes. The bear was not surprised and did not seem at all interested in the girl and her dog. The bear looked up at the girl and it was almost as if he was smiling at her. He then rested his head on his bear paws and went back to sleep. The girl and the dog kept walking and finally made it out of the woods. To this day the girl does not know why the bear was so friendly and to this day she has never told anyone about the meeting with the bear in the woods. After reading the above, is "No, she hasn't and her companion was her dog" the correct answer to the question "Has the girl or her companion told anyone about meeting the bear?"?

Answer:
yes

Question:
Enter the Shoguns: Japan's austere, ruthless, but statesmanlike new ruler, Yoritomo Minamoto, set up his government in Kamakura (just south of modern Tokyo), well away from the "softening" influence of court life that had been the undoing of his predecessor, Kiyomori. First of the national rulers to take the title of sei-i tai-shogun ("barbarian-subduing great general"), Minamoto expanded and consolidated his power by confiscating lands from some of the defeated Taira and redistributing them to his samurai vassals. Minamoto died in 1199, and the feudal structure passed intact to the tutelage of his widow's family, the Hojo, who were content to play regent to a figurehead shogun, in much the same way as the Fujiwara had done with the emperor. The fiction of Japanese imperial power had become infinitely extendable. The emperor at Kyotostill seconded by a Fujiwara regent at courtlegitimized a Minamoto who was himself a military dictator controlled by a Hojo regent. In a country where form and substance were inextricably interrelated, two things counted in politics: symbolic authority and real power. Neither could exist without the other. A thwarted Mongol invasion in 1274 weakened the Kamakura regime. The fighting brought none of the usual spoils of war that provincial warlords and samurai had come to expect as payment. And the treasury was empty after earthquake, famine, and plague had crippled the economy. Buddhist monasteries were using their private armies to support imperial ambitions to bring power back to Kyoto. Worst of all, the Kamakura warriors, resenting the way the Kyoto court referred to them as "Eastern barbarians," sought refinement in a ruinous taste for luxury: extravagant feasts, rich costumes, and opulent homes. Kamakura was falling apart. After reading the above, is "They are barbarians that have ruinous taste for luxury. With extravagant feasts, rich costumes, and opulent homes" the correct answer to the question "What are Eastern barbarians?"?

Answer:
yes

Question:
After arriving in New York City, Einstein was taken to various places and events, including Chinatown, a lunch with the editors of the New York Times, and a performance of Carmen at the Metropolitan Opera, where he was cheered by the audience on his arrival. During the days following, he was given the keys to the city by Mayor Jimmy Walker and met the president of Columbia University, who described Einstein as "The ruling monarch of the mind." Harry Emerson Fosdick, pastor at New York's Riverside Church, gave Einstein a tour of the church and showed him a full-size statue that the church made of Einstein, standing at the entrance. Also during his stay in New York, he joined a crowd of 15,000 people at Madison Square Garden during a Hanukkah celebration. Einstein next traveled to California where he met Caltech president and Nobel laureate, Robert A. Millikan. His friendship with Millikan was "awkward", as Millikan "had a penchant for patriotic militarism," where Einstein was a pronounced pacifist. During an address to Caltech's students, Einstein noted that science was often inclined to do more harm than good. This aversion to war also led Einstein to befriend author Upton Sinclair and film star Charlie Chaplin, both noted for their pacifism. Carl Laemmle, head of Universal Studios, gave Einstein a tour of his studio and introduced him to Chaplin. They had an instant rapport, with Chaplin inviting Einstein and his wife, Elsa, to his home for dinner. Chaplin said Einstein's outward persona, calm and gentle, seemed to conceal a "highly emotional temperament," from which came his "extraordinary intellectual energy." Chaplin also remembers Elsa telling him about the time Einstein conceived his theory of relativity. During breakfast one morning, he seemed lost in thought and ignored his food. She asked him if something was bothering him. He sat down at his piano and started playing. He continued playing and writing notes for half an hour, then went upstairs to his study, where he remained for two weeks, with Elsa bringing up his food. At the end of the two weeks he came downstairs with two sheets of paper bearing his theory. Chaplin's film, City Lights, was to premier a few days later in Hollywood, and Chaplin invited Einstein and Elsa to join him as his special guests. After reading the above, is "Ignored his food" the correct answer to the question "What were the events preceding Einstein's seclusion?"?

Answer:
yes
