Question: Which of the schools that Ari Brynjolfsson attended or worked at has existed the longest? Passage:Ari Brynjolfsson was born in Akureyri, Iceland, one of the seven children of Brynjólfur Sigtryggsson and Guðrún Rósinkarsdóttir from Hörgárdalur. He lived in Krossanes, Eyjafjörður and graduated from Menntaskólinn á Akureyri in 1948, then studied nuclear physics at the Niels Bohr Institute, University of Copenhagen, Denmark, from 1948 to 1954, gaining his PhD, with a thesis which dealt with a device he had constructed for accurately measuring magnetism in rocks. Following this he became a special research fellow of the University of Iceland from 1954 to 1955, then an Alexander von Humboldt fellow of the University of Göttingen, Germany, from 1955 to 1957. While at Göttingen he contributed important work in magnetic moments, using a self-devised instrument with which he and others provided the strongest evidence to that date for magnetic field reversals.

Question: What city did Stevens complete a Ph.D. in? Passage:In 1980, Stevens joined the Army under their split option training program and conducted basic training at Fort Dix, New Jersey and advanced individual training at Fort Sam Houston, Texas. While engaged in his military service, Stevens entered the University of Southern Maine in the Computer Science program in 1981. However, an enthusiastic professor (John Ricci) converted him to the study of Chemistry. He spent two summers working as an intern at the Brookhaven National Laboratory in Long Island with Professor Ricci, and Drs. Thomas Koetzle and Dick McMullan, where he first learned how to determine the molecular structure of compounds by X-ray and neutron diffraction. While there he also met a University of Southern California research team led by Dr. Robert Bau; after he obtained a Bachelor of Science degree in Chemistry at USM, he entered the University of Southern California in pursuit of a Doctor of Philosophy degree in Chemistry working with Professor Robert Bau and Nobel Laureate Professor, George Olah. He completed his Ph.D. in 26 months, graduating in 1988.

Question: Near what present day city is the Methana Volcano located? Passage:As with previous games in the God of War franchise, God of War: Ghost of Sparta is set in an alternate version of ancient Greece populated by the Olympian Gods, Titans, and other beings from Greek mythology. With the exception of flashbacks, the events are set between the games God of War (2005) and  (2007). Several locations are explored, including the fictional city of Atlantis (and later a sunken version). Atlantis is a mythical city erected by the Sea God Poseidon, and houses the Temple of Poseidon. Near the city is a real-world location, the Methana Volcano, which is contained by the archimedean screws and is also the prison of the Titan Thera, who is guarded by automatons. On the outskirts of the city is the Temple of the god Thanatos, the location of Death's Gate and portal to the Domain of Death. Other locations include the Island of Crete and its capital city, Heraklion, the Mounts of Aroania, the ancient city of Sparta (also home to the Temple of Ares), the Mounts of Laconia, and a brief scene above the city of Athens featuring Suicide Bluffs, the highest cliff in the city overlooking the Aegean Sea and a recurring location during Kratos' adventures.
