Problem: United States presidential election, 2004:

The following week, John Edwards won the South Carolina primary and finished a strong second in Oklahoma to Clark. Lieberman dropped out of the campaign the following day. Kerry dominated throughout February and his support quickly snowballed as he won caucuses and primaries, taking in a string of wins in Michigan, Washington, Maine, Tennessee, Washington, D.C., Nevada, Wisconsin, Utah, Hawaii, and Idaho. Clark and Dean dropped out during this time, leaving Edwards as the only real threat to Kerry. Kucinich and Sharpton continued to run despite poor results at the polls.

What primary was won by Sharpton?

A: unanswerable

Problem: Before printing was widely adopted in the 19th century, the Quran was transmitted in manuscripts made by calligraphers and copyists. The earliest manuscripts were written in Hijazi-type script. The Hijazi style manuscripts nevertheless confirm that transmission of the Quran in writing began at an early stage. Probably in the ninth century, scripts began to feature thicker strokes, which are traditionally known as Kufic scripts. Toward the end of the ninth century, new scripts began to appear in copies of the Quran and replace earlier scripts. The reason for discontinuation in the use of the earlier style was that it took too long to produce and the demand for copies was increasing. Copyists would therefore chose simpler writing styles. Beginning in the 11th century, the styles of writing employed were primarily the naskh, muhaqqaq, rayhani and, on rarer occasions, the thuluth script. Naskh was in very widespread use. In North Africa and Spain, the Maghribi style was popular. More distinct is the Bihari script which was used solely in the north of India. Nastaliq style was also rarely used in Persian world.
What is the name of the thicker-stroked writing used for the Quran beginning in the 8th century?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The final decades of the 20th century have seen the rise of a new interdisciplinary approach to studying human psychology, known collectively as cognitive science. Cognitive science again considers the mind as a subject for investigation, using the tools of psychology, linguistics, computer science, philosophy, and neurobiology. New methods of visualizing the activity of the brain, such as PET scans and CAT scans, began to exert their influence as well, leading some researchers to investigate the mind by investigating the brain, rather than cognition. These new forms of investigation assume that a wide understanding of the human mind is possible, and that such an understanding may be applied to other research domains, such as artificial intelligence.
What is the group that human psychology belongs to?
A: cognitive science

Context and question: The city has an average elevation of 43 metres (141 ft). Its highest elevations are two hills: the Cerro de Montevideo and the Cerro de la Victoria, with the highest point, the peak of Cerro de Montevideo, crowned by a fortress, the Fortaleza del Cerro at a height of 134 metres (440 ft). Closest cities by road are Las Piedras to the north and the so-called Ciudad de la Costa (a conglomeration of coastal towns) to the east, both in the range of 20 to 25 kilometres (16 mi) from the city center. The approximate distances to the neighbouring department capitals by road are, 90 kilometres (56 mi) to San Jose de Mayo (San Jose Department) and 46 kilometres (29 mi) to Canelones (Canelones Department).
How far is to the neighboring capitol of Canelones?
Answer: 46 kilometres

Question: Sub- and quotient groups are related in the following way: a subset H of G can be seen as an injective map H G, i.e. any element of the target has at most one element that maps to it. The counterpart to injective maps are surjective maps (every element of the target is mapped onto), such as the canonical map G G / N.y["] Interpreting subgroup and quotients in light of these homomorphisms emphasizes the structural concept inherent to these definitions alluded to in the introduction. In general, homomorphisms are neither injective nor surjective. Kernel and image of group homomorphisms and the first isomorphism theorem address this phenomenon.
Is there an answer to this question: What theory address the phenomenon of homomorphisms being neither injective nor surjective?

Answer: the first isomorphism theorem

Question: Similar examples abound. Macedonian, although mutually intelligible with Bulgarian, certain dialects of Serbian and to a lesser extent the rest of the South Slavic dialect continuum, is considered by Bulgarian linguists to be a Bulgarian dialect, in contrast with the contemporary international view and the view in the Republic of Macedonia, which regards it as a language in its own right. Nevertheless, before the establishment of a literary standard of Macedonian in 1944, in most sources in and out of Bulgaria before the Second World War, the southern Slavonic dialect continuum covering the area of today's Republic of Macedonia were referred to as Bulgarian dialects.
Is there an answer to this question: What do Bulgarian linguists regard the Macedonian language as?

Answer:
a Bulgarian dialect
