Problem: Santa Monica, California:

In 2006, crime in Santa Monica affected 4.41% of the population, slightly lower than the national average crime rate that year of 4.48%. The majority of this was property crime, which affected 3.74% of Santa Monica's population in 2006; this was higher than the rates for Los Angeles County (2.76%) and California (3.17%), but lower than the national average (3.91%). These per-capita crime rates are computed based on Santa Monica's full-time population of about 85,000. However, the Santa Monica Police Department has suggested the actual per-capita crime rate is much lower, as tourists, workers, and beachgoers can increase the city's daytime population to between 250,000 and 450,000 people.

Problem: The modern concept of an abstract group developed out of several fields of mathematics. The original motivation for group theory was the quest for solutions of polynomial equations of degree higher than 4. The 19th-century French mathematician Evariste Galois, extending prior work of Paolo Ruffini and Joseph-Louis Lagrange, gave a criterion for the solvability of a particular polynomial equation in terms of the symmetry group of its roots (solutions). The elements of such a Galois group correspond to certain permutations of the roots. At first, Galois' ideas were rejected by his contemporaries, and published only posthumously. More general permutation groups were investigated in particular by Augustin Louis Cauchy. Arthur Cayley's On the theory of groups, as depending on the symbolic equation n = 1 (1854) gives the first abstract definition of a finite group.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In April 2014, FIFA banned the club from buying players for the next two transfer windows following the violation of the FIFA's rules about the transfer of footballers aged under 18. A statement on FIFA's website read "With regard to the case in question, FC Barcelona has been found to be in breach of art. 19 of the Regulations in the case of ten minor players and to have committed several other concurrent infringements in the context of other players, including under Annexe 2 of the Regulations. The Disciplinary Committee regarded the infringements as serious and decided to sanction the club with a transfer ban at both national and international level for two complete and consecutive transfer periods, together with a fine of CHF 450,000. Additionally, the club was granted a period of 90 days in which to regularise the situation of all minor players concerned." FIFA rejected an appeal in August but the pending appeal to the Court of Arbitration for Sport allowed Barcelona to sign players during the summer of 2014.
When FIFA ban Barcelona from buying players?

Context and question: Another study from 2012 included 150 dental school students from University of Athens, the result showed that light hair colour (blonde/light ash brown) was predominant in 10.7% of the students. 36% had medium hair colour (Light brown/Medium darkest brown). 32% had darkest brown and 21% black (15.3 off black, 6% midnight black). In conclusion the hair colour of young Greeks are mostly brown, ranging from light to dark brown. with significant minorities having black and blonde hair. The same study also showed that the eye colour of the students was 14.6% blue/green, 28% medium (light brown) and 57.4% dark brown.

Question: Such a theory would be true with higher probability, because it cannot be attacked so easily: to falsify the first one, it is sufficient to find that the sun has stopped rising; to falsify the second one, one additionally needs the assumption that the given day has not yet been reached. Popper held that it is the least likely, or most easily falsifiable, or simplest theory (attributes which he identified as all the same thing) that explains known facts that one should rationally prefer. His opposition to positivism, which held that it is the theory most likely to be true that one should prefer, here becomes very apparent. It is impossible, Popper argues, to ensure a theory to be true; it is more important that its falsity can be detected as easily as possible.
Is there an answer to this question: What is less important than detecting the falsity of a theory?

Problem: Ottoman Empire:

Part of the Ottoman territories in the Balkans (such as Thessaloniki, Macedonia and Kosovo) were temporarily lost after 1402 but were later recovered by Murad II between the 1430s and 1450s. On 10 November 1444, Murad II defeated the Hungarian, Polish, and Wallachian armies under Wadysaw III of Poland (also King of Hungary) and John Hunyadi at the Battle of Varna, the final battle of the Crusade of Varna, although Albanians under Skanderbeg continued to resist. Four years later, John Hunyadi prepared another army (of Hungarian and Wallachian forces) to attack the Turks but was again defeated by Murad II at the Second Battle of Kosovo in 1448.

In what battle did Murad II leave as the victory in 1448?

A:
Second Battle of Kosovo
