[Q]: Context: We have dreams almost every night. Do you ever notice the colors of your dreams? Do you dream in black and white or do you dream in yellow, red and green? New research suggests that the type of television you watched as a child has a great effect on the color of your dreams. While almost all people under 25 dream in color, thousands of people over 55, all of whom were brought up with black and white TV sets, often dream in monochrome . "It suggests there could be a critical period in our childhood when watching films has a big impact on the way dreams are formed", said Eva Murzyn, a psychology student at Dundee University in Britain who carried out the study. Research from 1915 through the 1950s suggested that the vast majority of dreams are in black and white. But the tide turned in the sixties, and later results suggested that up to 83 percent of dreams contain some color. Since this period also marked the transition between black-and-white film and TV and Technicolor ,an obvious explanation was that the media had been painting people's dreams. However, there weren't any firm conclusions. But now Miss Murzyn believes she has proven the link. She made a survey of more than 60 people, half of whom were over 55 and half of whom were under 25. She asked the volunteers to answer a questionnaire on the color of their dreams and their childhood exposure to film and TV. She then analyzed her own data. Only 4.4 percent of the under-25s' dreams were black and white. The over-55s who had had access to color TV and film during their childhood also reported a very low proportion of just 7.3 percent. But the over-55s who only had access to black-and -white media reported dreaming in black and white about a quarter of the time. Even though they would have spent only a few hours a day watching TV or films, their attention and emotion would have been heightened during this time, leaving a deeper imprint on their mind, Miss Murzyn told the New Scientist. "The crucial time is between three and ten when we all begin to have the ability to dream", she said.

[Q]: Context: Coming off their bye week, the Lions played a Week 5 Black and Blue Division duel at home with the Chicago Bears. In the first quarter, Detroit trailed early as Bears kicker Robbie Gould got a 37-yard field goal. In the second quarter, the Lions continued to trail as QB Kyle Orton completed a 9-yard TD pass to RB Matt Forte and a 12-yard TD pass to WR/KR Devin Hester. In the third quarter, Chicago continued its domination as Forte got a 1-yard TD run, and CB Charles Tillman returned an interception 26 yards for a touchdown. Afterwards, Detroit got its only score of the game as rookie RB Kevin Smith scored on a 12-yard TD run. In the fourth quarter, the Bears sealed the win when Gould nailed a 45-yard field goal. 
 Question: How was the ball received ending in the longest touchdown run?
[A]: interception


[Q]: Context: The Clean Air Act of 1970 and the amendments since then have done a great job in requiring people to clean up the air over the United States. Emissions of the six major pollutants regulated by the Clean Air Act carbon monoxide, lead, nitrous oxides, ozone, sulfur dioxide, and particulates have decreased by more than 50%. Cars, power plants, and factories individually release less pollution than they did in the mid-20th century. But there are many more cars, power plants, and factories. Many pollutants are still being released and some substances have been found to be pollutants that were not known to be pollutants in the past. There is still much work to be done to continue to clean up the air. Reducing air pollution from vehicles can be done in a number of ways. Breaking down pollutants before they are released into the atmosphere. Motor vehicles emit less pollution than they once did because of catalytic converters (Figure 1.1). Catalytic converters contain a catalyst that speeds up chemical reactions and breaks down nitrous oxides, carbon monoxide, and VOCs. Catalytic converters only work when they are hot, so a lot of exhaust escapes as the car is warming up. Catalytic converters are placed on mod- ern cars in the United States. Making a vehicle more fuel efficient. Lighter, more streamlined vehicles need less energy. Hybrid vehicles have an electric motor and a rechargeable battery. The energy that would be lost during braking is funneled into charging the battery, which then can power the car. The internal combustion engine only takes over when power in the battery has run out. Hybrids can reduce auto emissions by 90% or more, but many models do not maximize the possible fuel efficiency of the vehicle. A plug-in hybrid is plugged into an electricity source when it is not in use, perhaps in a garage, to make sure that the battery is charged. Plug-in hybrids run for a longer time on electricity and so are less polluting than regular hybrids. Plug-in hybrids began to become available in 2010. Developing new technologies that do not use fossil fuels. Fueling a car with something other than a liquid organic-based fuel is difficult. A fuel cell converts chemical energy into electrical energy. Hydrogen fuel cells harness the energy released when hydrogen and oxygen come together to create water (Figure 1.2). Fuel cells are extremely efficient and they produce no pollutants. But developing fuel-cell technology has had many problems and no one knows when or if they will become practical. Pollutants are removed from the exhaust streams of power plants and industrial plants before they enter the atmo- sphere. Particulates can be filtered out, and sulfur and nitric oxides can be broken down by catalysts. Removing these oxides reduces the pollutants that cause acid rain. Particles are relatively easy to remove from emissions by using motion or electricity to separate particles from the gases. Scrubbers remove particles and waste gases from exhaust using liquids or neutralizing materials (Figure 1.3). Gases, such as nitrogen oxides, can be broken down at very high temperatures. A hydrogen fuel-cell car looks like a gasoline-powered car. Scrubbers remove particles and waste gases from exhaust. Gasification is a developing technology. In gasification, coal (rarely is another organic material used) is heated to extremely high temperatures to create syngas, which is then filtered. The energy goes on to drive a generator. Syngas releases about 80% less pollution than regular coal plants, and greenhouse gases are also lower. Clean coal plants do not need scrubbers or other pollution control devices. Although the technology is ready, clean coal plants are more expensive to construct and operate. Also, heating the coal to high enough temperatures uses a great deal of energy, so the technology is not energy efficient. In addition, large amounts of the greenhouse gas CO2 are still released with clean coal technology. Nonetheless, a few of these plants are operating in the United States and around the world. How can air pollution be reduced? Using less fossil fuel is one way to lessen pollution. Some examples of ways to conserve fossil fuels are: Riding a bike or walking instead of driving
