In the United States, a prom, short for promenade, is a formal dance held at the end of the years of high school and college, called junior prom and senior prom respectively. In British English such an event would be called a ball, although in Canada, Australia, and New Zealand it is also often called a formal. In Australian schools the terms used are either formal or sometimes as Leaver's Dinner, usually so when the night includes a meal. In Ireland it is known as a debs (an abbreviation of debutante ball). In the U.S. a "formal" is typically a similar dance that is held by a fraternity or sorority affiliated with a certain college or university. In Australia, the term "prom" has also come into sparse usage and in Britain it is becoming widespread, because of US influence. The name is derived from the late ninteenth century practice of a Promenade ball. The end of year tradition stemmed from the Graduation Ball tradition.

Ohio is a state in the United States. Historically a part of the Midwest, Ohio is a cultural and geographical crossroads, which was settled by people from New England, the Middle States, Appalachia, and the upper south. "This slice of the mid-west contains a bit of everything American—part north-eastern and part southern, part urban and part rural, part hardscrabble poverty and part booming suburb," notes The Economist.[1] Prior to 1984, the United States Census Bureau considered Ohio part of the North Central Region.[2] That region concept was renamed "Midwest" and split into two divisions. Ohio is now in the East North Central States division.[3] Ohio was the first state admitted to the Union under the Northwest Ordinance. Its U.S. postal abbreviation is OH; its old-style abbreviation is O. Ohio is an Iroquois word meaning "good river." The name refers to the Ohio River that forms its southern border. The U.S. Navy has named several ships USS Ohio in honor of this state. Economy Ohio is a major producer of machines, tires and rubber products, steel, processed foods, tools, and other manufactured goods. This is not immediately obvious because Ohio specializes in producers goods (goods used to make other goods, such as machine tools, industrial chemicals, and plastic moldings). Nevertheless, there are well known Ohio consumer items including some Procter & Gamble products, Smuckers jams and jellies, and Day-Glo paints. Ohio is the site of the invention of the airplane, resulting from the experiments of the Wright brothers in Dayton. Production of aircraft in the USA is now centered elsewhere, but a large experimental and design facility, Wright-Patterson Air Force Base has been located near Dayton and serves in the co-ordination of production of US military aircraft. On the base are located Wright Hill and Huffman Prairie, where many of the earliest aerodynamic experiments of the Wright brothers were performed. Ohio today also has many aerospace, defense, and NASA parts and systems suppliers scattered throughout the state. As part of the Corn Belt, agriculture also plays an important role in the state's economy. There is also a small commercial fishing sector on Lake Erie, and the principal catch is yellow perch. In addition, Ohio's historical attractions, varying landscapes, and recreational opportunities are the basis for a thriving tourist industry. Over 2,500 lakes and 43,000 miles (70,000 km) of river landscapes are a paradise for boaters, fishermen, and swimmers. Of special historical interest are the Native American archaeological sites—including grave mounds and other sites. The Bureau of Economic Analysis estimates that Ohio's gross state product in 2004 was $419 billion[1]. Per capita personal income in 2003 was $30,129, 25th in the nation. Ohio's agricultural outputs are soybeans, dairy products, corn, tomatoes, hogs, cattle, poultry and eggs. Its industrial outputs are transportation equipment, fabricated metal products, machinery, food processing, and electric equipment. Source: Wikipedia.org - English
