Problem: All YouTube users can upload videos up to 15 minutes each in duration. Users who have a good track record of complying with the site's Community Guidelines may be offered the ability to upload videos up to 12 hours in length, which requires verifying the account, normally through a mobile phone. When YouTube was launched in 2005, it was possible to upload long videos, but a ten-minute limit was introduced in March 2006 after YouTube found that the majority of videos exceeding this length were unauthorized uploads of television shows and films. The 10-minute limit was increased to 15 minutes in July 2010. If an up-to-date browser version is used, videos greater than 20 GB can be uploaded.
Who can upload videos of 15 hours in duration?

Context and question: After the Union of Horodło the Lithuanian nobility acquired equal status with the Polish szlachta, and over time began to become more and more polonized, although they did preserve their national consciousness, and in most cases recognition of their Lithuanian family roots. In the 16th century some of the Lithuanian nobility claimed that they were of Roman extraction, and the Lithuanian language was just a morphed Latin language. This led to paradox: Polish nobility claimed own ancestry from Sarmatian tribes, but Sarmatians were considered enemies to Romans. Thus new Roman-Sarmatian theory was created. Strong cultural ties with Polish nobility led that in the 16th century the new term to name Lithuanian nobility appeared šlėkta—a direct loanword from Polish szlachta. From the view of historical truth Lithuanians also should use this term, šlėkta (szlachta), to name own nobility, but Lithuanian linguists forbade the usage of this Polish loanword. This refusal to use word szlachta (in Lithuanian text šlėkta) complicates all naming.
What other group had equal status with the lithuanian nobility?
Answer: Polish szlachta


Question: New sequencing technologies, such as massive parallel sequencing have also opened up the prospect of personal genome sequencing as a diagnostic tool, as pioneered by Manteia Predictive Medicine. A major step toward that goal was the completion in 2007 of the full genome of James D. Watson, one of the co-discoverers of the structure of DNA.
Is there an answer to this question: What has James D. Watson recently develop that may lead to personal genome sequencing?

Answer: unanswerable


QUES: Jonassohn and Björnson postulate that the major reason why no single generally accepted genocide definition has emerged is because academics have adjusted their focus to emphasise different periods and have found it expedient to use slightly different definitions to help them interpret events. For example, Frank Chalk and Kurt Jonassohn studied the whole of human history, while Leo Kuper and R. J. Rummel in their more recent works concentrated on the 20th century, and Helen Fein, Barbara Harff and Ted Gurr have looked at post World War II events. Jonassohn and Björnson are critical of some of these studies, arguing that they are too expansive, and conclude that the academic discipline of genocide studies is too young to have a canon of work on which to build an academic paradigm.

What writer joined Jonassohn in the study of definitions?
