Passage: Efforts to identify the origins of Ashkenazi Jews through DNA analysis began in the 1990s. Currently, there are three types of genetic origin testing, autosomal DNA (atDNA), mitochondrial DNA (mtDNA), and Y-chromosomal DNA (Y-DNA). Autosomal DNA is a mixture from an individual's entire ancestry, Y-DNA shows a male's lineage only along his strict-paternal line, mtDNA shows any person's lineage only along the strict-maternal line. Genome-wide association studies have also been employed to yield findings relevant to genetic origins. Question: How many types of genetic origin testing currently exist?
answer:
three types of genetic origin testing


question:
Passage: Aonuma had anticipated creating a Zelda game for what would later be called the Wii, but had assumed that he would need to complete Twilight Princess first. His team began work developing a pointing-based interface for the bow and arrow, and Aonuma found that aiming directly at the screen gave the game a new feel, just like the DS control scheme for Phantom Hourglass. Aonuma felt confident this was the only way to proceed, but worried about consumers who had been anticipating a GameCube release. Developing two versions would mean delaying the previously announced 2005 release, still disappointing the consumer. Satoru Iwata felt that having both versions would satisfy users in the end, even though they would have to wait for the finished product. Aonuma then started working on both versions in parallel.[o] Question: Which Nintendo employee was confident in the potential of developing two versions of Twilight Princess?
answer:
Satoru Iwata


question:
Passage: Albert spent the first six months of 1913 on the training ship HMS Cumberland in the West Indies and on the east coast of Canada. He was rated as a midshipman aboard HMS Collingwood on 15 September 1913, and spent three months in the Mediterranean. His fellow officers gave him the nickname "Mr. Johnson". One year after his commission, he began service in the First World War. He was mentioned in despatches for his action as a turret officer aboard Collingwood in the Battle of Jutland (31 May – 1 June 1916), an indecisive engagement with the German navy that was the largest naval action of the war. He did not see further combat, largely because of ill health caused by a duodenal ulcer, for which he had an operation in November 1917. Question: How many months did Albert spend in the Mediterranean in 1913?
answer:

three months
