The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. The 48 contiguous states and Washington, D.C., are in North America between Canada and Mexico, while Alaska is in the far northwestern part of North America and Hawaii is an archipelago in the mid-Pacific. Territories of the United States are scattered throughout the Pacific Ocean and the Caribbean Sea.
States possess a number of powers and rights under the United States Constitution, such as regulating intrastate commerce, running elections, creating local governments, and ratifying constitutional amendments. Each state has its own constitution, grounded in republican principles, and government, consisting of three branches: executive, legislative, and judicial. All states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state is represented by two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state. Article IV, Section 3, Clause 1 of the Constitution grants to Congress the authority to admit new states into the Union. Since the establishment of the United States in 1776, the number of states has expanded from the original 13 to the current total of 50, and each new state is admitted on an equal footing with the existing states.As provided by Article I, Section 8 of the Constitution, Congress exercises "exclusive jurisdiction" over the federal district, which is not part of any state.

Europa  (listen), or Jupiter II, is the smallest of the four Galilean moons orbiting Jupiter, and the sixth-closest to the planet of all the 79 known moons of Jupiter. It is also the sixth-largest moon in the Solar System. Europa was discovered in 1610 by Galileo Galilei and was named after Europa, the Phoenician mother of King Minos of Crete and lover of Zeus (the Greek equivalent of the Roman god Jupiter).
Slightly smaller than Earth's Moon, Europa is primarily made of silicate rock and has a water-ice crust and probably an iron–nickel core. It has a very thin atmosphere, composed primarily of oxygen. Its surface is striated by cracks and streaks, but craters are relatively few. In addition to Earth-bound telescope observations, Europa has been examined by a succession of space-probe flybys, the first occurring in the early 1970s.
Europa has the smoothest surface of any known solid object in the Solar System. The apparent youth and smoothness of the surface have led to the hypothesis that a water ocean exists beneath the surface, which could conceivably harbor extraterrestrial life. The predominant model suggests that heat from tidal flexing causes the ocean to remain liquid and drives ice movement similar to plate tectonics, absorbing chemicals from the surface into the ocean below.

A trailer (also known as a preview or coming attraction) is a commercial advertisement for a feature film that will be exhibited in the future at a movie theater/cinema, the result of creative and technical work. The term "trailer" dates back to the distribution of movies on reels of film. The reels were always distributed un-rewound (the theater about to show the film first had to rewind it, as early experience showed the danger of expecting an incoming film to have been rewound). Therefore, the end of the movie was the most accessible part, to which previews were spliced, "trailing" the film.Movie trailers have now become popular on DVDs and Blu-ray discs, as well as on the Internet and mobile devices. Of some 10 billion videos watched online annually, film trailers rank third, after news and user-created video. The trailer format has also been adopted as a promotional tool for television shows, video games, books, and theatrical events/concerts.


== History ==

The first trailer shown in an American film theater was in November 1913, when Nils Granlund, the advertising manager for the Marcus Loew theater chain, produced a short promotional film for the musical The Pleasure Seekers, opening at the Winter Garden Theatre on Broadway. As reported in a wire service story carried by the Lincoln, Nebraska Daily Star, the practice which Loew adopted was described as "an entirely new and unique stunt", and that "moving pictures of the rehearsals and other incidents connected with the production will be sent out in advance of the show, to be presented to the Loew's picture houses and will take the place of much of the bill board advertising". Granlund was also first to introduce trailer material for an upcoming motion picture, using a slide technique to promote an upcoming film featuring Charlie Chaplin at Loew's Seventh Avenue Theatre in Harlem in 1914.Trailers were initially shown after, or "trailing", the feature film, and this led to their being called "trailers". The practice was found to be somewhat ineffective, often ignored by audiences who left immediately after the feature.

The NRG Astrodome, also known as the Houston Astrodome or simply the Astrodome, is the world's first multi-purpose, domed sports stadium, located in Houston, Texas. It was financed and assisted in development by Roy Hofheinz, mayor of Houston and known for pioneering modern stadiums. Construction on the stadium began in 1962, and it officially opened in 1965. It served as home to the Houston Astros of Major League Baseball (MLB) from its opening until 1999, and the home to the Houston Oilers of the National Football League (NFL) from 1968 until 1996, and also the part-time home of the Houston Rockets of the National Basketball Association (NBA) from 1971 until 1975. Additionally, the Astrodome was the primary venue of the Houston Livestock Show and Rodeo from 1966 until 2002. When opened, it was named the Harris County Domed Stadium and was nicknamed the "Eighth Wonder of the World".
After the original natural grass playing surface died, the Astrodome became the first major sports venue to install artificial turf, which became known as AstroTurf. In another technological first, the Astrodome featured the "Astrolite", which was the first animated scoreboard. The Astrodome was renovated in 1988, expanding seating and altering many original features.
By the 1990s, the Astrodome was becoming obsolete.

Oreo () is an American sandwich cookie consisting of two (usually chocolate) wafers or biscuits with a sweet crème filling. Introduced on March 6, 1912, Oreo is the best-selling cookie brand in the United States. As of 2018, the version sold in the U.S. is made by the Nabisco division of Mondelez International.
Oreo cookies are available in over one hundred countries. Many varieties of Oreo cookies have been produced, and limited-edition runs have become popular in the 21st century.


== Etymology ==
The origin of the name "Oreo" is unknown, but there are many hypotheses, including derivations from the French word or, meaning 'gold', or from an Ancient Greek root meaning 'mountain'. Others believe that the cookie was named Oreo simply because the name was short and easy to pronounce. Another theory, proposed by food writer Stella Parks, is that the name derives from the Latin Oreodaphne, a genus of the laurel family. She observes that the original design of the Oreo includes a laurel wreath; and the names of several of Nabisco's cookies at the time of the original Oreo had botanical derivations, including Avena, Lotus, and Helicon (from Heliconia).


== History ==


=== Twentieth century ===
The "Oreo Biscuit" was first developed and produced by the National Biscuit Company (today known as Nabisco) in 1912 at its Chelsea, New York City factory in the present-day Chelsea Market complex, located on Ninth Avenue between 15th and 16th Streets.

The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Adult sea otters typically weigh between 14 and 45 kg (31 and 99 lb), making them the heaviest members of the weasel family, but among the smallest marine mammals. Unlike most marine mammals, the sea otter's primary form of insulation is an exceptionally thick coat of fur, the densest in the animal kingdom. Although it can walk on land, the sea otter is capable of living exclusively in the ocean.

The sea otter inhabits nearshore environments, where it dives to the sea floor to forage. It preys mostly on marine invertebrates such as sea urchins, various mollusks and crustaceans, and some species of fish. Its foraging and eating habits are noteworthy in several respects. First, its use of rocks to dislodge prey and to open shells makes it one of the few mammal species to use tools. In most of its range, it is a keystone species, controlling sea urchin populations which would otherwise inflict extensive damage to kelp forest ecosystems. Its diet includes prey species that are also valued by humans as food, leading to conflicts between sea otters and fisheries.

Sweden (; Swedish: Sverige [ˈsvæ̌rjɛ] (listen)), officially the Kingdom of Sweden (Swedish: Konungariket Sverige [ˈkôːnɵŋaˌriːkɛt ˈsvæ̌rjɛ] (listen)), is a Nordic country in Northern Europe. It borders Norway to the west and north, Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund Strait. At 450,295 square kilometres (173,860 sq mi), Sweden is the largest country in Northern Europe, the third-largest country in the European Union, and the fifth largest country in Europe. The capital city is Stockholm. Sweden has a total population of 10.4 million; and a low population density of 25 inhabitants per square kilometre (65/sq mi). 87% of Swedes live in urban areas, which cover 1.5% of the entire land area. The highest concentration is in the central and southern half of the country.
Sweden is part of the geographical area of Fennoscandia. The climate is in general mild for its northerly latitude due to significant maritime influence. In spite of the high latitude, Sweden often has warm continental summers, being located in between the North Atlantic, the Baltic Sea, and vast Russia.

Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. It is the largest country in Oceania and the world's sixth-largest country by total area. Its population of nearly 26 million is highly urbanised and heavily concentrated on the eastern seaboard. Australia's capital is Canberra, and its largest city is Sydney. The country's other major metropolitan areas are Melbourne, Brisbane, Perth, and Adelaide.
Indigenous Australians inhabited the continent for about 65,000 years prior to the first arrival of Dutch explorers in the early 17th century, who named it New Holland. In 1770, Australia's eastern half was claimed by Great Britain and initially settled through penal transportation to the colony of New South Wales from 26 January 1788, a date which became Australia's national day. The population grew steadily in subsequent decades, and by the time of an 1850s gold rush, most of the continent had been explored by European settlers and an additional five self-governing crown colonies established. On 1 January 1901, the six colonies federated, forming the Commonwealth of Australia. Australia has since maintained a stable liberal democratic political system that functions as a federal parliamentary constitutional monarchy, comprising six states and ten territories.

The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers over 70 percent of the Earth's surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea.
The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Humans harnessing and studying the sea have been recorded since ancient times, and evidenced well into prehistory, while its modern scientific study is called oceanography. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary little across the oceans. Winds blowing over the surface of the sea produce waves, which break when they enter the shallow water. Winds also create surface currents through friction, setting up slow but stable circulations of water throughout the oceans. The directions of the circulation are governed by factors, including the shapes of the continents and Earth's rotation (the Coriolis effect).

The groundhog (Marmota monax), also known as a woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. 
The groundhog is a lowland creature of North America; it is found through much of the eastern United States, across Canada and into Alaska. 
It was first scientifically described by Carl Linnaeus in 1758.The groundhog is also referred to as a chuck, wood-shock, groundpig, whistlepig, whistler, thickwood badger, Canada marmot, monax, moonack, weenusk, red monk, land beaver, and, among French Canadians in eastern Canada, siffleux.The name "thickwood badger" was given in the Northwest to distinguish the animal from the prairie badger. Monax (Móonack) is an Algonquian name of the woodchuck, which means "digger" (cf. Lenape monachgeu). Young groundhogs may be called chucklings.The groundhog, being a lowland animal, is exceptional among marmots. Other marmots, such as the yellow-bellied and hoary marmots, live in rocky and mountainous areas. Groundhogs maintain an important role in maintaining many healthy soil in woodland and plain areas. Groundhogs are an extremely intelligent animal forming complex social networks, and understand complex social behavior, form kinship with their young, understand and communicate threats, and are able to work cooperatively to solve tasks such as burrowing. Due to this the Groundhog is considered a crucial habitat engineer.

Ketchup is a table condiment. The unmodified term ("ketchup") now typically refers to tomato ketchup, although original recipes used egg whites, mushrooms, oysters, grapes, mussels, or walnuts, among other ingredients.Tomato ketchup is a sweet and tangy condiment made from tomatoes, sugar, and vinegar, with seasonings and spices. The spices and flavors vary, but commonly include onions, allspice, coriander, cloves, cumin, garlic, and mustard, and sometimes include celery, cinnamon, or ginger. The market leader in the United States (60% market share) and the United Kingdom (82%) is Heinz Tomato Ketchup. Tomato ketchup is most often used as a condiment to dishes that are usually served hot and may be fried or greasy: french fries and other potatoes, hamburgers, hot dogs, chicken tenders, tater tots, hot sandwiches, meat pies, cooked eggs, and grilled or fried meat. Ketchup is sometimes used as the basis for, or as one ingredient in, other sauces and dressings, and the flavor may be replicated as an additive flavoring for snacks, such as potato chips.


== History ==


=== Mushroom ketchup ===

In the United Kingdom, preparations of ketchup were historically and originally prepared with mushrooms as a primary ingredient, rather than tomatoes. Ketchup recipes began to appear in British and then American cookbooks in the 18th century. In a 1742 London cookbook, the fish sauce had already taken on a very British flavor, with the addition of shallots and mushrooms. The mushrooms soon became the main ingredient and from 1750 to 1850 the word "ketchup" began to mean any number of thin dark sauces made of mushrooms or even walnuts.

Sloths are a group of arboreal Neotropical xenarthran mammals, constituting the suborder Folivora. Noted for their slowness of movement, they spend most of their lives hanging upside down in the trees of the tropical rainforests of South America and Central America. They are considered to be most closely related to anteaters, together making up the xenarthran order Pilosa. 
There are six extant sloth species in two genera – Bradypus (three–toed sloths) and Choloepus (two–toed sloths). Despite this traditional naming, all sloths actually have three toes on each rear limb, although two-toed sloths have only two digits on each forelimb. The two groups of sloths are from different, distantly related families, and are thought to have evolved their morphology via parallel evolution from terrestrial ancestors. Besides the extant species, many species of ground sloths ranging up to the size of elephants (like Megatherium) inhabited both North and South America during the Pleistocene Epoch. However, they became extinct during the Quaternary extinction event around 12,000 years ago, together with most large bodied animals in the New World. The extinction correlates in time with the arrival of humans, but climate change has also been suggested to have contributed. Members of an endemic radiation of Caribbean sloths formerly lived in the Greater Antilles.
