It is a regularly occurring and official count of a particular population. The term is used mostly in connection with national population and housing censuses; other common censuses include agriculture, business, and traffic censuses. The United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every 10 years. United Nations recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practice., Sacramento is the capital city of the U.S. state of California and the seat of Sacramento County. It is at the confluence of the Sacramento River and the American River in the northern portion of California's expansive Central Valley. Its estimated 2014 population of 485,199 made it the sixth-largest city in California, and the 35th largest city in the United States. Sacramento is the cultural and economic core of the Sacramento metropolitan area, which includes seven counties with a 2010 population of 2,414,783. Its metropolitan area is the fourth largest in California after the Greater Los Angeles area, the San Francisco Bay Area, and the San Diego metropolitan area, and is the 27th largest in the United States. In 2002, the Civil Rights Project at Harvard University conducted for "Time" magazine named Sacramento "America's Most Diverse City"., The Sacramento River is the principal river of Northern California in the United States, and is the largest river in California. Rising in the Klamath Mountains, the river flows south for before reaching the SacramentoSan Joaquin River Delta and San Francisco Bay. The river drains about in 19 California counties, mostly within the fertile agricultural region bounded by the Coast Ranges and Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California. Historically, its watershed has reached as far north as south-central Oregon where the now, primarily, endorheic (closed) Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento., A radio station is a set of equipment necessary to carry on communication via radio waves. Generally, it is a receiver or transmitter, an antenna, and some smaller additional equipment necessary to operate them. Radio stations play a vital role in communication technology as they are heavily relied on to transfer data and information across the world., Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 GHz to as low as 3 kHz, though some definitions describe waves above 1 or 3 GHz as microwaves, or include waves of any lower frequency. At 300 GHz, the corresponding wavelength is , and at 3 kHz is . Like all other electromagnetic waves, they travel at the speed of light. Naturally occurring radio waves are generated by lightning, or by astronomical objects. , The San Francisco Bay Area (referred to locally as the Bay Area) is a populous region surrounding the San Francisco and San Pablo estuaries in Northern California. The region encompasses the major cities and metropolitan areas of San Jose, San Francisco, and Oakland, along with smaller urban and rural areas. The Bay Area's nine counties are Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. Home to approximately 7.65 million people, the nine-county Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a network of roads, highways, railroads, bridges, tunnels and commuter rail. The combined statistical area of the region is the second-largest in California (after the Greater Los Angeles area), the fifth-largest in the United States, and the 43rd-largest urban area in the world., Jackson (formerly, Botilleas, Botilleas Spring, Bottileas, Bottle Spring, and Botellas) is the county seat of Amador County, California.

Context: African-American music is an umbrella term covering a diverse range of musics and musical genres largely developed by African Americans. Their origins are in musical forms that arose out of the historical condition of slavery that characterized the lives of African Americans prior to the American Civil War., Fritz Weiss ( Czech : Bedich Weiss ) ( 28 September 1919 - 28 September 1944 ) was a jazz musician and arranger , active in the first half of the 20th century . He was an organizer of jazz performances and an important participant in the musical life of the Theresienstadt concentration camp . Weiss was one of the victims of the Holocaust ., The Jazz Age was a period in the 1920s, ending with the Great Depression, in which jazz music and dance styles became popular, mainly in the United States, but also in Britain, France and elsewhere. Jazz originated in New Orleans as a fusion of African and European music and played a significant part in wider cultural changes in this period, and its influence on pop culture continued long afterwards. The Jazz Age is often referred to in conjunction with the Roaring Twenties., Blues is a genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. The genre developed from roots in African musical traditions, African-American work songs and European-American folk music. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds or fifths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove., West Africa, also called Western Africa and the West of Africa, is the westernmost subregion of Africa. West Africa has been defined as including 18 countries: Benin, Burkina Faso, the island nation of Cape Verde, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Mali, Mauritania, Niger, Nigeria, the island of Saint Helena, Senegal, Sierra Leone, São Tomé and Príncipe and Togo., Improvisation is broad term referring to the process of devising an atypical method of solving a problem due to lack of time or resources. In a technical context, this can mean adapting a device for some use other than that which it was designed for, or building a device from unusual components in an ad-hoc fashion. Improvisation, within the context of performing arts, is a very spontaneous performance without specific or scripted preparation. The skills of improvisation can apply to many different faculties, across all artistic, scientific, physical, cognitive, academic, and non-academic disciplines., Terezín is a former military fortress composed of citadel and adjacent walled garrison town of Litomice District, in the Ústí nad Labem Region of the Czech Republic., Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km² (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition., Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms"., A ghetto is a part of a city in which members of a minority group live, especially because of social, legal, or economic pressure. The term was originally used in Venice to describe the part of the city to which Jews were restricted and segregated. The term has been applied in various contexts., Ragtime  also spelled rag-time or rag time  is a musical genre that enjoyed its peak popularity between 1895 and 1918. Its cardinal trait is its syncopated, or "ragged", rhythm. The genre has its origins in African-American communities like St. Louis years before being published as popular sheet music for piano. Ernest Hogan (18651909) was a pioneer of ragtime music and was the first to compose ragtime into sheet music. The composition was called "LA Pas Ma LA" and it was released in 1895. Hogan has also been credited for coining the term "ragtime". The term is actually derived from his hometown "Shake Rag" in Bowling Green, Kentucky. Ben Harney, who is also a Kentucky native has often been credited for introducing the music to the mainstream public. His first ragtime composition "You've been a good old wagon but you done broke" helped popularize the musical genre. The composition was published in 1895 but released in 1896. Ragtime was also a modification of the march made popular by John Philip Sousa, with additional polyrhythms coming from African music. The ragtime composer Scott Joplin ("ca." 18681917) became famous through the publication of the "Maple Leaf Rag" (1899) and a string of ragtime hits such as "The Entertainer" (1902), although he was later forgotten by all but a small, dedicated community of ragtime aficionados until the major ragtime revival in the early 1970s. For at least 12 years after its publication, "Maple Leaf Rag" heavily influenced subsequent ragtime composers with its melody lines, harmonic progressions or metric patterns., Theresienstadt concentration camp, also referred to as Theresienstadt ghetto, was a concentration camp established by the SS during World War II in the garrison city of Terezín, located in German-occupied Czechoslovakia., Subject: fritz weiss, Relation: country_of_citizenship, Options: (A) academic (B) american (C) benin (D) burkina faso (E) czech republic (F) czechoslovakia (G) earth (H) france (I) ghana (J) guinea (K) madagascar (L) mauritania (M) niger (N) senegal (O) venice

Context: Deoxyribonucleic acid (DNA) is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses. DNA and RNA are nucleic acids; alongside proteins, lipids and complex carbohydrates (polysaccharides), they are one of the four major types of macromolecules that are essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix., Oral cancer, also known as mouth cancer, is a type of head and neck cancer and is any cancerous tissue growth located in the oral cavity., Molecular biology concerns the molecular basis of biological activity between biomolecules in the various systems of a cell, including the interactions between DNA, RNA, and proteins and their biosynthesis, as well as the regulation of these interactions. Writing in "Nature" in 1961, William Astbury described molecular biology as:, Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes. RNA and DNA are nucleic acids, and, along with proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA it is more often found in nature as a single-strand folded onto itself, rather than a paired double-strand. Cellular organisms use messenger RNA (mRNA) to convey genetic information (using the letters G, U, A, and C to denote the nitrogenous bases guanine, uracil, adenine, and cytosine) that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome., A biomolecule or biological molecule is molecule that is present in living organisms, including large macromolecules such as proteins, carbohydrates, lipids, and nucleic acids, as well as small molecules such as primary metabolites, secondary metabolites, and natural products. A more general name for this class of material is biological materials. Biomolecules are usually endogenous but may also be exogenous. For example, pharmaceutical drugs may be natural products or semisynthetic (biopharmaceuticals) or they may be totally synthetic., William Thomas Astbury FRS (also Bill Astbury; 25 February 1898, Longton  4 June 1961, Leeds) was an English physicist and molecular biologist who made pioneering X-ray diffraction studies of biological molecules. His work on keratin provided the foundation for Linus Pauling's discovery of the alpha helix. He also studied the structure for DNA in 1937 and made the first step in the elucidation of its structure., Head and neck cancer is a group of cancers that starts within the mouth, nose, throat, larynx, sinuses, or salivary glands. Symptoms may include a lump or sore that does not heal, a sore throat that does not go away, trouble swallowing, or a change in the voice. There may also be unusual bleeding, facial swelling, or trouble breathing.
About 80% of head and neck cancer is due to the use of alcohol or tobacco. Other risk factors include betel quid, certain types of human papillomavirus, radiation exposure, certain workplace exposures, and Epstein-Barr virus. Head and neck cancers are most commonly of the squamous cell carcinoma type. The diagnosis is confirmed by tissue biopsy. The degree of spread may be determined by medical imaging and blood tests.
Prevention is by not using tobacco or alcohol. While screening in the general population does not appear to be useful, screening high risk groups by examination of the throat might be useful. Often head and neck cancer is curable if detected early; however, outcomes are typically poor if detected late. Treatment may include a combination of surgery, radiation therapy, chemotherapy, and targeted therapy. Following treatment of one head and neck cancer people are at higher risk of a second cancer.
In 2013 head and neck cancers globally affected more than 4.6 million people (mouth 2.4 million, throat 1.3 million, larynx 0.9 million) and resulted in more than 362,000 deaths (mouth 135,000, throat 139,000, larynx 88,000). Together they are the seventh most frequent cancer and the ninth most frequent cause of death from cancer. In the United States about one percent of people are affected at some point in their life and males are affected twice as often as females. The usual age at diagnosis is between 55 and 65 years. The average 5 year survival following diagnosis in the developed world is 42 to 64%., Dr. Xiaofeng Zhou , (  ) Associate Professor , Center for Molecular Biology of Oral Diseases , University of Illinois at Chicago College of Dentistry , is an internationally known oral cancer researcher .
