Problem: A cappella:

A cappella [a kapˈpɛlla] (Italian for "in the manner of the chapel") music is specifically group or solo singing without instrumental accompaniment, or a piece intended to be performed in this way. It contrasts with cantata, which is accompanied singing. The term "a cappella" was originally intended to differentiate between Renaissance polyphony and Baroque concertato style. In the 19th century a renewed interest in Renaissance polyphony coupled with an ignorance of the fact that vocal parts were often doubled by instrumentalists led to the term coming to mean unaccompanied vocal music. The term is also used, albeit rarely, as a synonym for alla breve.

Problem: The subsequent Slave dynasty of Delhi managed to conquer large areas of northern India, while the Khilji dynasty conquered most of central India but were ultimately unsuccessful in conquering and uniting the subcontinent. The Sultanate ushered in a period of Indian cultural renaissance. The resulting "Indo-Muslim" fusion of cultures left lasting syncretic monuments in architecture, music, literature, religion, and clothing. It is surmised that the language of Urdu (literally meaning "horde" or "camp" in various Turkic dialects) was born during the Delhi Sultanate period as a result of the intermingling of the local speakers of Sanskritic Prakrits with immigrants speaking Persian, Turkic, and Arabic under the Muslim rulers. The Delhi Sultanate is the only Indo-Islamic empire to enthrone one of the few female rulers in India, Razia Sultana (1236–1240).

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During the High Middle Ages, which began after 1000, the population of Europe increased greatly as technological and agricultural innovations allowed trade to flourish and the Medieval Warm Period climate change allowed crop yields to increase. Manorialism, the organisation of peasants into villages that owed rent and labour services to the nobles, and feudalism, the political structure whereby knights and lower-status nobles owed military service to their overlords in return for the right to rent from lands and manors, were two of the ways society was organised in the High Middle Ages. The Crusades, first preached in 1095, were military attempts by Western European Christians to regain control of the Holy Land from the Muslims. Kings became the heads of centralised nation states, reducing crime and violence but making the ideal of a unified Christendom more distant. Intellectual life was marked by scholasticism, a philosophy that emphasised joining faith to reason, and by the founding of universities. The theology of Thomas Aquinas, the paintings of Giotto, the poetry of Dante and Chaucer, the travels of Marco Polo, and the architecture of Gothic cathedrals such as Chartres are among the outstanding achievements toward the end of this period, and into the Late Middle Ages.
What year marked the beginning of the High Middle Ages?
A: 1000


Context and question: Some of the most renowned and highly ranked universities in the world are located in the Boston area. Four members of the Association of American Universities are in Greater Boston (more than any other metropolitan area): Harvard University, the Massachusetts Institute of Technology, Boston University, and Brandeis University. Hospitals, universities, and research institutions in Greater Boston received more than $1.77 billion in National Institutes of Health grants in 2013, more money than any other American metropolitan area. Greater Boston has more than 100 colleges and universities, with 250,000 students enrolled in Boston and Cambridge alone. Its largest private universities include Boston University (the city's fourth-largest employer) with its main campus along Commonwealth Avenue and a medical campus in the South End; Northeastern University in the Fenway area; Suffolk University near Beacon Hill, which includes law school and business school; and Boston College, which straddles the Boston (Brighton)–Newton border. Boston's only public university is the University of Massachusetts Boston, on Columbia Point in Dorchester. Roxbury Community College and Bunker Hill Community College are the city's two public community colleges. Altogether, Boston's colleges and universities employ over 42,600 people, accounting for nearly 7 percent of the city's workforce.
How many students are enrolled in boston and Cambridge?

Question: St. John's economy is connected to both its role as the provincial capital of Newfoundland and Labrador and to the ocean. The civil service which is supported by the federal, provincial and municipal governments has been the key to the expansion of the city's labour force and to the stability of its economy, which supports a sizable retail, service and business sector. The provincial government is the largest employer in the city, followed by Memorial University. With the collapse of the fishing industry in Newfoundland and Labrador in the 1990s, the role of the ocean is now tied to what lies beneath it – oil and gas – as opposed to what swims in or travels across it. The city is the centre of the oil and gas industry in Eastern Canada and is one of 19 World Energy Cities. ExxonMobil Canada is headquartered in St. John's and companies such as Chevron, Husky Energy, Suncor Energy and Statoil have major regional operations in the city. Three major offshore oil developments, Hibernia, Terra Nova and White Rose, are in production off the coast of the city and a fourth development, Hebron, is expected to be producing oil by 2017.
Is there an answer to this question: Who is the largest employer in the province?

Answer: unanswerable
