Input: Consider Input: Context: The film opens on October 30, 1988, nearly ten years after Michael Myers's last murderous rampage in Haddonfield, Illinois. An ambulance from Smith's Grove, IL makes its way along the road in a thunderstorm toward the Ridgemont Federal Sanitarium, where Michael, who has been in a coma since then, has been incarcerated. After the apprehensive transfer crew is seen off by medical chief of staff Dr. Hoffman, the ambulance makes its way up the driveway in the storm and back out onto the highway toward Smith's Grove. While in the ambulance, he hears that eight-year-old Jamie Lloyd, his niece and the daughter of Laurie Strode, his first target, is residing in Haddonfield. He immediately grabs and repeatedly bashes a hospital attendant's head against the wall of the ambulance and stabs his finger right into his skull. The other attendant, trapped by the ambulance's locked doors, can only watch helplessly. Soon after, the film introduces Jamie, who has been adopted by the Carruthers family and is still mourning the loss of her mother. Laurie supposedly died in a car accident eleven months earlier. Her older foster sister Rachel comes into her room and consoles her, telling her that she will love her just as much as her mother did. Rachel sends Jamie off to bed and exits the room. Jamie kneels down next to the bed and says her prayers when suddenly, lightning and thunder crash outside, startling her. The door creaks open and as Jamie gets up to close it, the reflection of Michael, donned in his classic white mask and black coveralls, appears in the mirror. Jamie returns to her bed and instantly, Michael's hand reaches out from under the bed and grabs her by the leg. Jamie struggles, gets loose, and runs to her closet. Opening the door, a second Michael appears in front of her, raising his knife. Jamie screams again, attracting the attention of her foster mother, Darlene, who rushes into the room. She finds Jamie, shaking on the floor of her closet, traumatized after what was only a horrific nightmare.Dr. Loomis angrily marches into Hoffman's office the next day, berating him about the transfer of Michael Myers. Hoffman explains that it was mandated by federal law; as he does, he is interrupted by a phone call informing him of an accident involving the ambulance that was carrying Michael Myers. Immediately Loomis smells trouble, and the two men drive to the site of the accident. The state police have secured the scene; the ambulance is upside-down in a river with blood on both the outside & interior. One trooper tells Hoffman it was likely an accident, but Loomis does not believe it. Despite Hoffman's admonishments, Loomis wades into the river & walks round to the ambulance's rear. Inside is a scene of horror; blood is sprayed all over the walls & floor of the ambulance. Immediately, Loomis heads toward Haddonfield, certain that Michael Myers is headed there. Meanwhile, at a gas station, a mechanic works beneath a car, calling for someone to hand him a wrench. When he hears no response, he slides out. There is Michael, raising a long, sharp pole in the air. He thrusts it down into the mechanic's stomach, killing him instantly. Loomis soon after arrives at the gas station and finds the mechanic's body, hanging by a chain from the roof. He also finds several other bodies and immediately sees Michael, standing against the back wall. Loomis shoots at him, but Michael disappears. Loomis scurries out to the exterior of the gas station, barely catching Michael driving away in a truck. Just after, the entire gas station explodes. Loomis survives after crouching behind a nearby barrel.Meanwhile, Jamie is coming home from school to see several kids coming upon her, taunting her that she has no mother. Jamie runs from the scene, crying. At home, Rachel plans to go out for Halloween with her boyfriend, Brady, but her parents refuse and force her to take Jamie trick-or-treating. Rachel protests and Jamie overhears, upset at the fact that Rachel 
 Question: Where does Dr. Loomis arrives?

Output: hoffman's office; the crime scene of the ambulance; gas station


Input: Consider Input: Context: For travellers who want to experience some of the history and mystery of the ancient world, here is a list of cool destinations for your next holiday. Angkor Wat, Cambodia Built in the 12th century, Angkor Wat (meaning "capital monastery") was a temple in the ancient Khmer capital city of Angkor. It is Cambodia's best-known tourist attraction and is famed for its beautiful architecture and reliefs. You'll need at least three days to fully discover the delights of this magnificent site. Machu Picchu, Peru Machu Picchu was built high in the Andes Mountains of South America by the Inca in the 15th century. Although well preserved its exact purpose is unknown. It is famous throughout the world not only for its incredible design but also for the natural beauty that surrounds it. Give yourself a week to explore this magnificent site. Stonehenge, England The entire Stonehenge site was constructed over thousands of years. But why and how it was built remains a mystery. As the weather can be pretty bleak in winter and the crowds huge in summer, we suggest autumn should be the best time to visit these monster rocks. Pompeii, Italy When Mount Vesuvius erupted in 79 A.D., Pompeii was buried under many layers of ash, preserving the city exactly as it was when the volcano erupted. Because so many objects were preserved, scientists and visitors are able to better understand daily life in the ancient Roman Empire. 
 Question: Which location offers the most direct view into daily life in the ancient world?

Output: pompeii.


Input: Consider Input: Context: Air quality is a measure of the pollutants in the air. More pollutants mean poorer air quality. Air quality, in turn, depends on many factors. Some natural processes add pollutants to the air. For example, forest fires and volcanoes add carbon dioxide and soot. In dry areas, the air often contains dust. However, human actions cause the most air pollution. The single biggest cause is fossil fuel burning. Poor air quality started to become a serious problem after the Industrial Revolution. The machines in factories burned coal. This released a lot of pollutants into the air. After 1900, motor vehicles became common. Cars and trucks burn gasoline, which adds greatly to air pollution. By the mid-1900s, air quality in many big cities was very bad. The worst incident came in December 1952. A temperature inversion over London, England, kept cold air and pollutants near the ground. The air became so polluted that thousands of people died in just a few days. This event was called the Big Smoke. At the same time, many U.S. cities had air pollution problems. Some of the worst were in California. Cars were becoming more popular. Oil refineries and power plants also polluted the air. Mountain ranges trapped polluted air over cities. The California sunshine caused chemical reactions among the pollutants. These reactions produced many more harmful compounds. By 1970, it was clear that something needed to be done to protect air quality. In the U.S., the Clean Air Act was passed. It limits what can be released into the air. As a result, the air in the U.S. is much cleaner now than it was 50 years ago. But air pollution has not gone away. Vehicles, factories, and power plants still release more than 150 million tons of pollutants into the air each year. There are two basic types of pollutants in air. They are known as primary pollutants and secondary pollutants. Primary pollutants enter the air directly. Some are released by natural processes, like ash from volcanoes. Most are released by human activities. They pour into the air from vehicles and smokestacks. Several of these pollutants are described below. Carbon oxides include carbon monoxide (CO) and carbon dioxide (CO2 ). Carbon oxides are released when fossil fuels burn. Nitrogen oxides include nitric oxide (NO) and nitrogen dioxide (NO2 ). Nitrogen oxides form when nitrogen and oxygen combine at high temperatures. This occurs in hot exhausts from vehicles, factories, and power plants. Sulfur oxides include sulfur dioxide (SO2 ) and sulfur trioxide (SO3 ). Sulfur oxides are produced when sulfur and oxygen combine. This happens when coal burns. Coal can contain up to 10 percent sulfur. Toxic heavy metals include mercury and lead. Mercury is used in some industrial processes. It is also found in fluorescent light bulbs. Lead was once widely used in gasoline, paint, and pipes. It is still found in some products. Volatile organic compounds (VOCs) are carbon compounds such as methane. VOCs are released in many human activities, such as raising livestock. Livestock wastes produce a lot of methane. Particulates are solid particles. These particles may be ash, dust, or even animal wastes. Many are released when fossil fuels burn (see Figure 22.1). Secondary pollutants form when primary pollutants undergo chemical reactions after they are released. Many occur as part of photochemical smog. This type of smog is seen as a brown haze in the air. Photochemical smog forms when certain pollutants react together in the presence of sunlight. You can see smog hanging in the air over San Francisco in Figure 22.2. Photochemical smog consists mainly of ozone (O3 ). The ozone in smog is the same compound as the ozone in the ozone layer,(O3 ). But ozone in smog is found near the ground. Figure 22.3 shows how it forms. When nitrogen oxides and VOCs are heated by the Sun, they lose oxygen atoms. The oxygen atoms combine with molecules of oxygen to form ozone. Smog ozone is harmful to humans and other living things. Most pollutants enter the air when fossil fuels burn. Some are released when forests burn.
