Background: Hanson is an American pop rock band from Tulsa, Oklahoma, United States, formed by brothers Isaac (guitar, bass, piano, vocals), Taylor (keyboards, piano, guitar, drums, vocals), and Zac (drums, piano, guitar, vocals). Supporting members include Dimitrius Collins (keyboards, guitar), and Andrew Perusi (bass) who have toured and performed live with the band since 2007. They are best known for the 1997 hit song "MMMBop" from their debut album released through Mercury, Polygram, Middle of Nowhere, which earned three Grammy nominations. Despite the enormous commercial success of Middle of Nowhere, the band suffered from the merger that eliminated their label, Mercury Records .
Context: In the early to mid-1990s, Isaac, Taylor and Zac sang a cappella and recorded such classic songs as "Rockin' Robin", "Splish Splash" and "Johnny B. Goode", as well as their own material. Their first performance as a professional group took place in 1992 at the Mayfest Arts Festival in Tulsa. They were known as the Hanson Brothers, before shortening the name to Hanson in 1993.  Hanson also appeared on Carman's Yo! Kidz: The Vidz, which cast Taylor as a young Biblical David facing Goliath, Isaac as an event announcer, and Zac and other members of the family in the stands cheering on this "sporting event".  All three boys started their musical careers as pianists, but Isaac eventually started playing guitar and Zac started playing drums, while Taylor continued as the keyboard player. The band recorded two independent albums in their hometown of Tulsa, Boomerang (recorded in autumn 1994, released in 1995) and MMMBop (released in 1996). The latter featured the original version of the song "MMMBop", which would later become the runaway single on their debut commercial record Middle of Nowhere. The boys then found themselves at the South By Southwest (aka SXSW) music festival in Austin, Texas. There, they were promptly signed by manager Christopher Sabec. He shopped them to several record companies, most of which dismissed the band as either a novelty or fraud before Steve Greenberg, an A&R representative for Mercury Records, heard them play a set at the Wisconsin State Fair. After this performance, they were signed almost immediately by Mercury. They soon became a worldwide sensation with the release of their first major-label album, Middle of Nowhere, which was produced by Stephen Lironi and the Dust Brothers.

Problem: Background: Ukrainians (Ukrainian: ukrayintsi, ukrayintsi, [ukra'jinjtsji]) are an East Slavic ethnic group native to Ukraine, which is by total population the sixth-largest nation in Europe. The Constitution of Ukraine applies the term 'Ukrainians' to all its citizens. Also among historical names of the people of Ukraine, Rusyns (Ruthenians), Cossacks, etc. can be found. According to most dictionary definitions, a descriptive name for the "inhabitants of Ukraine" is Ukrainian or Ukrainian people.
Context: Most ethnic Ukrainians live in Ukraine, where they make up over three-quarters of the population. The largest population of ethnic Ukrainians outside of Ukraine lives in Russia where about 1.9 million Russian citizens consider themselves ethnic Ukrainians, while millions of others (primarily in southern Russia and Siberia) have some Ukrainian ancestry. The inhabitants of the Kuban, for example, have vacillated among three identities: Ukrainian, Russian (an identity supported by the Soviet regime), and "Cossack". Approximately 800,000 people of Ukrainian ancestry live in the Russian Far East in an area known historically as "Green Ukraine".  According to some previous assumptions, an estimated number of almost 2.4 million people of Ukrainian origin live in North America (1,359,655 in Canada and 1,028,492 in the United States). Large numbers of Ukrainians live in Brazil (600,000), Kazakhstan (338,022), Moldova (325,235), Argentina (305,000), Germany (272,000), Italy (234,354), Belarus (225,734), Uzbekistan (124,602), the Czech Republic (110,245), Spain (90,530-100,000) and Romania (51,703-200,000). There are also large Ukrainian communities in such countries as Latvia, Portugal, France, Australia, Paraguay, the UK, Israel, Slovakia, Kyrgyzstan, Austria, Uruguay and the former Yugoslavia. Generally, the Ukrainian diaspora is present in more than one hundred and twenty countries of the world.  The number of Ukrainians in Poland amounted to some 51,000 people in 2011 (according to Polish Census). Since 2014, the country has experienced a large increase in immigration from Ukraine. More recent data put the number of Ukrainian workers at 1.2 - 1.3 million in 2016.  In the last decades of the 19th century, many Ukrainians were forced by the Tsarist autocracy to move to the Asian regions of Russia, while many of their counterpart Slavs under Austro-Hungarian rule emigrated to the New World seeking work and better economic opportunities. Today, large ethnic Ukrainian minorities reside in Russia, Canada, the United States, Brazil, Kazakhstan, Italy and Argentina. According to some sources, around 20 million people outside Ukraine identify as having Ukrainian ethnicity, however the official data of the respective countries calculated together doesn't show more than 10 million. Ukrainians have one of the largest diasporas in the world.
