Input: Read this: In the past, many organizations have claimed ownership of patents related to MP3 decoding or encoding. These claims led to a number of legal threats and actions from a variety of sources. As a result, uncertainty about which patents must be licensed in order to create MP3 products without committing patent infringement in countries that allow software patents was a common feature of the early stages of adoption of the technology.
Question: Legal threats and confusion made it difficult to ensure what about patents regarding MP3 products?

Output: which patents must be licensed

QUES: Kadamba (345 525 CE) was an ancient royal dynasty of Karnataka, India that ruled northern Karnataka and the Konkan from Banavasi in present-day Uttara Kannada district. At the peak of their power under King Kakushtavarma, the Kadambas of Banavasi ruled large parts of modern Karnataka state. The dynasty was founded by Mayurasharma in 345 CE which at later times showed the potential of developing into imperial proportions, an indication to which is provided by the titles and epithets assumed by its rulers. King Mayurasharma defeated the armies of Pallavas of Kanchi possibly with help of some native tribes. The Kadamba fame reached its peak during the rule of Kakusthavarma, a notable ruler with whom even the kings of Gupta Dynasty of northern India cultivated marital alliances. The Kadambas were contemporaries of the Western Ganga Dynasty and together they formed the earliest native kingdoms to rule the land with absolute autonomy. The dynasty later continued to rule as a feudatory of larger Kannada empires, the Chalukya and the Rashtrakuta empires, for over five hundred years during which time they branched into minor dynasties known as the Kadambas of Goa, Kadambas of Halasi and Kadambas of Hangal.

QUES: Italy is home to a vast array of native regional minority languages, most of which are Romance-based and have their own local variants. These regional languages are often referred to colloquially or in non-linguistic circles as Italian "dialects," or dialetti (standard Italian for "dialects"). However, the majority of the regional languages in Italy are in fact not actually "dialects" of standard Italian in the strict linguistic sense, as they are not derived from modern standard Italian but instead evolved locally from Vulgar Latin independent of standard Italian, with little to no influence from what is now known as "standard Italian." They are therefore better classified as individual languages rather than "dialects."
Most of Italy's languages have what kind of base along with shared variants?

ANS: unanswerable

Marwan was succeeded by his son, Abd al-Malik (685705), who reconsolidated Umayyad control of the caliphate. The early reign of Abd al-Malik was marked by the revolt of Al-Mukhtar, which was based in Kufa. Al-Mukhtar hoped to elevate Muhammad ibn al-Hanafiyyah, another son of Ali, to the caliphate, although Ibn al-Hanafiyyah himself may have had no connection to the revolt. The troops of al-Mukhtar engaged in battles both with the Umayyads in 686, defeating them at the river Khazir near Mosul, and with Ibn al-Zubayr in 687, at which time the revolt of al-Mukhtar was crushed. In 691, Umayyad troops reconquered Iraq, and in 692 the same army captured Mecca. Ibn al-Zubayr was killed in the attack.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was the father of Muhammad ibn al-Hanafiyyah?
Ah, so.. Ali

Question: In 1949, the city was chosen to be the seat of the Council of Europe with its European Court of Human Rights and European Pharmacopoeia. Since 1952, the European Parliament has met in Strasbourg, which was formally designated its official 'seat' at the Edinburgh meeting of the European Council of EU heads of state and government in December 1992. (This position was reconfirmed and given treaty status in the 1997 Treaty of Amsterdam). However, only the (four-day) plenary sessions of the Parliament are held in Strasbourg each month, with all other business being conducted in Brussels and Luxembourg. Those sessions take place in the Immeuble Louise Weiss, inaugurated in 1999, which houses the largest parliamentary assembly room in Europe and of any democratic institution in the world. Before that, the EP sessions had to take place in the main Council of Europe building, the Palace of Europe, whose unusual inner architecture had become a familiar sight to European TV audiences. In 1992, Strasbourg became the seat of the Franco-German TV channel and movie-production society Arte.
Try to answer this question if possible: How many days each month is Council of Europe business conducted in Brussels and Luxembourg?
Answer: unanswerable

Problem: The elections of 2010 resulted in a victory for the military-backed Union Solidarity and Development Party. Various foreign observers questioned the fairness of the elections. One criticism of the election was that only government sanctioned political parties were allowed to contest in it and the popular National League for Democracy was declared illegal. However, immediately following the elections, the government ended the house arrest of the democracy advocate and leader of the National League for Democracy, Aung San Suu Kyi, and her ability to move freely around the country is considered an important test of the military's movement toward more openness. After unexpected reforms in 2011, NLD senior leaders have decided to register as a political party and to field candidates in future by-elections.
