Problem: Ashkenazi Jews:

A 2013 trans-genome study carried out by 30 geneticists, from 13 universities and academies, from 9 countries, assembling the largest data set available to date, for assessment of Ashkenazi Jewish genetic origins found no evidence of Khazar origin among Ashkenazi Jews. "Thus, analysis of Ashkenazi Jews together with a large sample from the region of the Khazar Khaganate corroborates the earlier results that Ashkenazi Jews derive their ancestry primarily from populations of the Middle East and Europe, that they possess considerable shared ancestry with other Jewish populations, and that there is no indication of a significant genetic contribution either from within or from north of the Caucasus region", the authors concluded.

What did the 2013 trans-genome study find in regards to Ashkenazi Jews and Khazar origins?

A: found no evidence of Khazar origin among Ashkenazi Jews

Problem: 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.
What years did the fishing industry fall in Newfoundland and Labrador?
---
Answer: 1990s

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Energy transfer can be considered for the special case of systems which are closed to transfers of matter. The portion of the energy which is transferred by conservative forces over a distance is measured as the work the source system does on the receiving system. The portion of the energy which does not do work during the transfer is called heat.[note 4] Energy can be transferred between systems in a variety of ways. Examples include the transmission of electromagnetic energy via photons, physical collisions which transfer kinetic energy,[note 5] and the conductive transfer of thermal energy.
The portion of energy which works during the transfer is called what?
A: unanswerable

Context and question: The Standard Output Sensitivity (SOS) technique, also new in the 2006 version of the standard, effectively specifies that the average level in the sRGB image must be 18% gray plus or minus 1/3 stop when the exposure is controlled by an automatic exposure control system calibrated per ISO 2721 and set to the EI with no exposure compensation. Because the output level is measured in the sRGB output from the camera, it is only applicable to sRGB imagestypically JPEGand not to output files in raw image format. It is not applicable when multi-zone metering is used.
Multi-zone metering uses what ISO calibration?
Answer: unanswerable

Question: The Reed Dance today is not an ancient ceremony but a development of the old "umchwasho" custom. In "umchwasho", all young girls were placed in a female age-regiment. If any girl became pregnant outside of marriage, her family paid a fine of one cow to the local chief. After a number of years, when the girls had reached a marriageable age, they would perform labour service for the Queen Mother, ending with dancing and feasting. The country was under the chastity rite of "umchwasho" until 19 August 2005.
Is there an answer to this question: Until what date was Swaziland bound by umchwasho?

Answer: 19 August 2005

On December 24, Yeltsin informed the Secretary-General of the United Nations that by agreement of the member states of the CIS Russian Federation would assume the membership of the Soviet Union in all UN organs (including permanent membership in the UN Security Council). Thus, Russia is considered to be an original member of the UN (since October 24, 1945) along with Ukraine (Ukrainian SSR) and Belarus (Byelorussian SSR). On December 25just hours after Gorbachev resigned as president of the Soviet Unionthe Russian SFSR was renamed the Russian Federation (Russia), reflecting that it was now a sovereign state with Yeltsin assuming the Presidency. The change was originally published on January 6, 1992 (Rossiyskaya Gazeta). According to law, during 1992, it was allowed to use the old name of the RSFSR for official business (forms, seals and stamps). The Russian Federation's Constitution (Fundamental Law) of 1978, though with the 19911992 Amendements, remained in effect until the 1993 Russian constitutional crisis.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what periodical was the new sovereign status of the Russian Federation last published?
Ah, so..
unanswerable
