Input: Read this: Bermuda's modern black population contains more than one demographic group. Although the number of residents born in Africa is very small, it has tripled between 2000 and 2010 (this group also includes non-blacks). The majority of blacks in Bermuda can be termed "Bermudian blacks", whose ancestry dates back centuries between the 17th century and the end of slavery in 1834, Bermuda's black population was self-sustaining, with its growth resulting largely from natural expansion. This contrasts to the enslaved blacks of the plantation colonies, who were subjected to conditions so harsh as to drop their birth rate below the death rate, and slaveholders in the United States and the West Indies found it necessary to continue importing more enslaved blacks from Africa until the end of slavery (the same had been true for the Native Americans that the Africans had replaced on the New World plantations). The indigenous populations of many West Indian islands, and much of the South-East of what is now the United States that had survived the 16th- and 17th-century epidemics of European-introduced diseases then became the victims of large-scale slave raiding, with much of the region completely depopulated. When the supply of indigenous slaves ran out, the slaveholders looked to Africa). The ancestry of Bermuda's black population is distinguished from that of the British West Indian black population in two ways: firstly, the higher degree of European and Native American admixture; secondly, the source of the African ancestry.
Question: What is one way that the ancestry of Bermudian black population differs from that of British West Indian black population?

Output: the source of the African ancestry


Input: Read this: The percentage of students attending a Gesamtschule varies by Bundesland. In the State of Brandenburg more than 50% of all students attended a Gesamtschule in 2007, while in the State of Bavaria less than 1% did.
Question: What percentage of Bavarian students went to a Gesamtschule in 2007?

Output: less than 1%


Input: Read this: Cladistics is a technique borrowed from biology, where it was originally named phylogenetic systematics by Willi Hennig. In biology, the technique is used to determine the evolutionary relationships between different species. In its application in textual criticism, the text of a number of different manuscripts is entered into a computer, which records all the differences between them. The manuscripts are then grouped according to their shared characteristics. The difference between cladistics and more traditional forms of statistical analysis is that, rather than simply arranging the manuscripts into rough groupings according to their overall similarity, cladistics assumes that they are part of a branching family tree and uses that assumption to derive relationships between them. This makes it more like an automated approach to stemmatics. However, where there is a difference, the computer does not attempt to decide which reading is closer to the original text, and so does not indicate which branch of the tree is the "root"—which manuscript tradition is closest to the original. Other types of evidence must be used for that purpose.
Question: What is the biological basis for Cladistics?

Output: to determine the evolutionary relationships between different species


Input: Read this: The term "Immersive app" had been used internally by Microsoft developers to refer to the apps prior to the first official presentation of Windows 8, after which they were referred to as "Metro-style apps" in reference to the Metro design language. The term was phased out in August 2012; a Microsoft spokesperson denied rumors that the change was related to a potential trademark issue, and stated that "Metro" was only a codename that would be replaced prior to Windows 8's release. Following these reports, the terms "Modern UI-style apps", "Windows 8-style apps" and "Windows Store apps" began to be used by various Microsoft documents and material to refer to the new apps. In an interview on September 12, 2012, Soma Somasegar (vice president of Microsoft's development software division) confirmed that "Windows Store apps" would be the official term for the apps. An MSDN page explaining the Metro design language uses the term "Modern design" to refer to the language as a whole.
Question: What doesn't immersive app stand for?

Output:
unanswerable
