Input: Read this: In July 1943, as a result of the American Federation of Musicians boycott of US recording studios, the a cappella vocal group The Song Spinners had a best-seller with "Comin' In On A Wing And A Prayer". In the 1950s several recording groups, notably The Hi-Los and the Four Freshmen, introduced complex jazz harmonies to a cappella performances. The King's Singers are credited with promoting interest in small-group a cappella performances in the 1960s. In 1983 an a cappella group known as The Flying Pickets had a Christmas 'number one' in the UK with a cover of Yazoo's (known in the US as Yaz) "Only You". A cappella music attained renewed prominence from the late 1980s onward, spurred by the success of Top 40 recordings by artists such as The Manhattan Transfer, Bobby McFerrin, Huey Lewis and the News, All-4-One, The Nylons, Backstreet Boys and Boyz II Men.[citation needed]
Question: Who is credited for first introducing elements of Jazz into a cappella?

Output: The Hi-Los and the Four Freshmen


QUES: The atolls have shown resilience to gradual sea-level rise, with atolls and reef islands being able to grow under current climate conditions by generating sufficient sand and coral debris that accumulates and gets dumped on the islands during cyclones. Gradual sea-level rise also allows for coral polyp activity to increase the reefs. However, if the increase in sea level occurs at faster rate as compared to coral growth, or if polyp activity is damaged by ocean acidification, then the resilience of the atolls and reef islands is less certain. The 2011 report of Pacific Climate Change Science Program of Australia concludes, in relation to Tuvalu, states the conclusions that over the course of the 21st century:

What does gradual sea level rise allow for coral to increase?
What is the answer?
ANS: reefs


QUES: Although most often associated with the People's Republic of China, character simplification predates the 1949 communist victory. Caoshu, cursive written text, almost always includes character simplification, and simplified forms have always existed in print, albeit not for the most formal works. In the 1930s and 1940s, discussions on character simplification took place within the Kuomintang government, and a large number of Chinese intellectuals and writers have long maintained that character simplification would help boost literacy in China. Indeed, this desire by the Kuomintang to simplify the Chinese writing system (inherited and implemented by the Communist Party of China) also nursed aspirations of some for the adoption of a phonetic script based on the Latin script, and spawned such inventions as the Gwoyeu Romatzyh.
What is Caoshu?

ANS: cursive written text


The deeper ancestral demography of Bermuda's population has been obscured by the ethnic homogenisation of the last four centuries. There is effectively no ethnic distinction between black and white Bermudians, other than those characterising recent immigrant communities. In the 17th century, this was not so. For the first hundred years of settlement, white Protestants of English heritage were the distinct majority, with white minorities of Irish (the native language of many of whom can be assumed to have been Gaelic) and Scots sent to Bermuda after the English invasions of their homelands that followed the English Civil War. Non-white minorities included Spanish-speaking, free (indentured) blacks from the West Indies, black chattel slaves primarily captured from Spanish and Portuguese ships by Bermudian privateers, and Native Americans, primarily from the Algonquian and other tribes of the Atlantic seaboard, but possibly from as far away as Mexico. By the 19th century, the white ethnically-English Bermudians had lost their numerical advantage. Despite the banning of the importation of Irish, and the repeated attempts to force free blacks to emigrate and the owners of black slaves to export them, the merging of the various minority groups, along with some of the white English, had resulted in a new demographic group, "coloured" (which term, in Bermuda, referred to anyone not wholly of European ancestry) Bermudians, gaining a slight majority. Any child born before or since then to one coloured and one white parent has been added to the coloured statistic. Most of those historically described as "coloured" are today described as "black", or "of African heritage", which obscures their non-African heritage (those previously described as "coloured" who were not of African ancestry had been very few, though the numbers of South Asians, particularly, is now growing. The number of persons born in Asian countries doubled between the 2000 and the 2010 censuses), blacks have remained in the majority, with new white immigration from Portugal, Britain and elsewhere countered by black immigration from the West Indies.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): There has been a double in the population of people born in which country?
Ah, so.. Asian


Question: Mean speeds vary greatly, but is typically around 1 m (3 ft) per day. There may be no motion in stagnant areas; for example, in parts of Alaska, trees can establish themselves on surface sediment deposits. In other cases, glaciers can move as fast as 20–30 m (70–100 ft) per day, such as in Greenland's Jakobshavn Isbræ (Greenlandic: Sermeq Kujalleq). Velocity increases with increasing slope, increasing thickness, increasing snowfall, increasing longitudinal confinement, increasing basal temperature, increasing meltwater production and reduced bed hardness.
Try to answer this question if possible: What makes some glaciers stagnant?
Answer: unanswerable


Input: Read this: The concept of racial origin relies on the notion that human beings can be separated into biologically distinct "races", an idea generally rejected by the scientific community. Since all human beings belong to the same species, the ECRI (European Commission against Racism and Intolerance) rejects theories based on the existence of different "races". However, in its Recommendation ECRI uses this term in order to ensure that those persons who are generally and erroneously perceived as belonging to "another race" are not excluded from the protection provided for by the legislation. The law claims to reject the existence of "race", yet penalize situations where someone is treated less favourably on this ground.
Question: What community rejects the idea there are biologically distinct races?

Output:
scientific
