Q: Passage: Hilda Rix Nicholas (née Rix, later Wright, 1 September 1884 – 3 August 1961) was an Australian artist. Hilda Rix was born in the Victorian city of Ballarat. Her father was an education administrator and poet, her mother was a musician and artist. She studied under a leading member of the Heidelberg School, Frederick McCubbin, at the National Gallery of Victoria Art School from 1902 to 1905 and was an early member of the Melbourne Society of Women Painters and Sculptors. Following the death of her father in 1907, Hilda Rix, her only sibling Elsie and her mother travelled to Europe where she undertook further study in London and then in Paris. Her teachers during the period included John Hassall, Richard Emil Miller and Théophile Steinlen.
After travelling to Tangiers in 1912, Rix held several successful exhibitions of her work, with one drawing, Grande marche, Tanger, purchased by the French government. She was one of the first Australians to paint post-impressionist landscapes, was made a member of the Société des Peintres Orientalistes Français, and had works hung in the Paris Salon first in 1911 and again in 1913. The family evacuated from France to England after the outbreak of World War I. A period of personal tragedy followed, as Rix's sister died in 1914, then her mother in 1915. In 1916 she met and married George Matson Nicholas, only to be widowed the next month when he was killed on the Western Front.
Returning to Australia in 1918, Rix Nicholas once more took up professional painting, and held an exhibition of over a hundred works at Melbourne's Guild Hall. Many sold, including In Picardy, purchased by the National Gallery of Victoria. Following a period painting in rural locations in the early 1920s, Rix Nicholas returned to Europe. A 1925 exhibition in Paris led to the sale of her work In Australia to the Musée du Luxembourg, followed by an extensive tour of her paintings around regional British art galleries. There followed representation in other exhibitions, including at the International Society of Sculptors, Painters and Gravers, and the Royal Academy of Arts, both in London. Following the inclusion of several works in the 1926 Société Nationale des Beaux-Arts Spring exhibition in Paris she was made an Associate of that organisation. 
Question: What is the full name of the person who studied at the National Gallery of Victoria Art School?

A: Hilda Rix Nicholas.

Q: Passage: Zappa expressed opinions on censorship when he appeared on CNN's Crossfire TV series and debated issues with Washington Times commentator John Lofton in 1986. On September 19, 1985, Zappa testified before the United States Senate Commerce, Technology, and Transportation committee, attacking the Parents Music Resource Center or PMRC, a music organization co-founded by Tipper Gore, wife of then-senator Al Gore. The PMRC consisted of many wives of politicians, including the wives of five members of the committee, and was founded to address the issue of song lyrics with sexual or satanic content. During Zappa's testimony, he stated that there was a clear conflict of interest between the PMRC due to the relations of its founders to the politicians who were then trying to pass what he referred to as the "Blank Tape Tax." Kandy Stroud, a spokeswoman for the PMRC, announced that Senator Gore (who co-founded the committee) was a co-sponsor of that legislation. Zappa suggested that record labels were trying to get the bill passed quickly through committees, one of which was chaired by Senator Strom Thurmond, who was also affiliated with the PMRC. Zappa further pointed out that this committee was being used as a distraction from that bill being passed, which would lead only to the benefit of a select few in the music industry.Zappa saw their activities as on a path towards censorship, and called their proposal for voluntary labelling of records with explicit content "extortion" of the music industry.In his prepared statement, he said:
The PMRC proposal is an ill-conceived piece of nonsense which fails to deliver any real benefits to children, infringes the civil liberties of people who are not children, and promises to keep the courts busy for years dealing with the interpretational and enforcemental problems inherent in the proposal's design. It is my understanding that, in law, First Amendment issues are decided with a preference for the least restrictive alternative. In this context, the PMRC's demands are the equivalent of treating dandruff by decapitation. ... The establishment of a rating system, voluntary or otherwise, opens the door to an endless parade of moral quality control programs based on things certain Christians do not like. What if the next bunch of Washington wives demands a large yellow "J" on all material written or performed by Jews, in order to save helpless children from exposure to concealed Zionist doctrine?Zappa set excerpts from the PMRC hearings to Synclavier music in his composition "Porn Wars" on the 1985 album Frank Zappa Meets the Mothers of Prevention, and the full recording was released in 2010 as Congress Shall Make No Law... Zappa is heard interacting with Senators Fritz Hollings, Slade Gorton and Al Gore. 
Question: What is the first name of the person who saw the PMRC's activities as on a path towards censorship, and called their proposal for voluntary labelling of records with explicit content "extortion" of the music industry?

A: Frank.

Q: Passage: The most important nautical innovation of the Song period seems to have been the introduction of the magnetic mariner's compass, which permitted accurate navigation on the open sea regardless of the weather. The magnetized compass needle – known in Chinese as the "south-pointing needle" – was first described by Shen Kuo in his 1088 Dream Pool Essays and first mentioned in active use by sailors in Zhu Yu's 1119 Pingzhou Table Talks.
There were other considerable advancements in hydraulic engineering and nautical technology during the Song dynasty. The 10th-century invention of the pound lock for canal systems allowed different water levels to be raised and lowered for separated segments of a canal, which significantly aided the safety of canal traffic and allowed for larger barges. There was the Song-era innovation of watertight bulkhead compartments that allowed damage to hulls without sinking the ships. If ships were damaged, the Chinese of the 11th century employed drydocks to repair them while suspended out of the water. The Song used crossbeams to brace the ribs of ships in order to strengthen them in a skeletal-like structure. Stern-mounted rudders had been mounted on Chinese ships since the 1st century, as evidenced with a preserved Han tomb model of a ship. In the Song period, the Chinese devised a way to mechanically raise and lower rudders in order for ships to travel in a wider range of water depths. The Song arranged the protruding teeth of anchors in a circular pattern instead of in one direction. David Graff and Robin Higham state that this arrangement "[made] them more reliable" for anchoring ships. 
Question: Who were the first people to use the magnetized compass needle?

A:
sailors.
