Problem: 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. 

Question: "What determines how a ball will bounce off a surface?"

Answer: "The temperature"
Answer: no

Problem: The grant also will help victims go through court proceedings after losing a job or being evicted because of an abuser's actions, Xanthopoulos said. "It's going to help the victims, but it's also going to help their children," he said. More than 270 domestic violence assaults in Madison County were reported last year, according to Tennessee Bureau of Investigation statistics. In Jackson, more than 730 domestic violence assaults were reported last year, according to records. "Domestic violence is certainly on the increase and we need to do something to curve that. I see this as helping that," Madison County Sheriff David Woolfork said of the grant. Domestic violence accounted for five of 12 murders in 2001 in Jackson, police have said. And the increase in calls prompted Jackson Police Chief Rick Staples in March to form a focus group to determine if police officers need to make changes in their response to domestic calls. 

Question: "Who did Xanthnopoulos say the grant would help?"

Answer: "Going to help the victim but also their children"
Answer: yes

Problem: New Legitimacy: Organized crime was soon to have a formidable adversary in its bid to control Las Vegas — corporate cash. Though Las Vegas had developed a powerful local economy, few major outside investments were made in the city, due primarily to mob infiltration and its inherent ties to illegal activities. That would change dramatically with the 1966 arrival of billionaire Howard Hughes. A legitimate businessman, Hughes was nonetheless eccentric and dramatic, a style suited to the Las Vegas ethos. True to the myth, the reclusive Hughes immediately cloistered himself in the Desert Inn's penthouse. Several weeks later he was asked — then ordered — to vacate the room to make room for high rollers, whereupon he promptly bought the property and fired the management. Thus began Hughes' legendary three-year, $300-million Las Vegas buying spree. When it was over, Hughes owned six casinos, an airport, and an airline, along with numerous plots of land stretching from the Strip to the mountains. Hughes' actions would have beneficial repercussions, both immediate and lasting. Because of the new legitimacy Las Vegas acquired from Hughes' investments, established companies such as Hilton Hotels bought into the gaming business, and their influence helped draw a line in the desert sand between legitimate operations and mob casinos, where illegal skimming of profits was rampant. That, combined with the formation of the Nevada Gaming Control Board, would signal the beginning of the end for heavy mob influence in the city. Las Vegas with a Vision As corporations moved in and the mob was slowly pushed out, a new Las Vegas emerged. The legitimization of gambling led to its increased legalization across the US. What was once a sure thing became much more competitive. Casino operators had to reassess the nature of their business. The first to really do so was Steve Wynn, a Las Vegas resident and owner of the Golden Nugget. In the mid-1980s, Wynn began plans to reinvigorate Las Vegas with a new resort. He bought several Strip properties — the Silver Slipper and Castaways among them — and demolished them to make way for a new kind of resort — Mirage —  which became an instant success. 

Question: "What did Hughes do as soon as he arrived in Vegas in 1966?"

Answer: "He bought a casino"

no
