[EX Q]: Question: Who piloted the airplane that killed Mulgrew Nunatak in 1979? Passage 1:Carter started his career as an apprentice at Brighton & Hove Albion but failed to make the grade for the first team. He made his first team debut in April 1987 in a 1–1 draw with Blackburn Rovers, coming on as a substitute and almost scoring with his first touch. He subsequently dropped down to the Isthmian League where he spent a season with Billericay Town. He was signed by Fourth Division side Leyton Orient in July 1988 and remained a first team regular in his seven-year spell at the club, which included promotion to the Third Division in his first season with via the play-offs. In June 1995, he joined newly relegated Second Division side Peterborough United for a fee of £25,000. He was a first team regular in his first season with the club but dropped out of the side in his second season as the club narrowly avoided relegation twice. Following his release he spent time on trial at Cambridge United and Wycombe Wanderers, however, both were unsuccessful in earning a full-time contract. He subsequently signed for Welsh Premier League side Barry Town, where he spent two seasons and made a total of sixty league appearances, scoring ten goals. He later joined Southern League Premier side Merthyr Tydfil in 1999 and spent six seasons with the club making over 200 appearances. He was also the club captain. In the summer of 2005 he signed for newly promoted Welsh Premier League side Cardiff Grange Harlequins but only made eight league appearances and the side couldn't avoid relegation at the first attempt.
 Passage 2:Mulgrew Nunatak () is a prominent nunatak, 1,600 m, standing four nautical miles (7 km) east of Tentacle Ridge in the Cook Mountains. Its summit, standing at , is named Peter Crest. The nunatak was first mapped by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58). Both it and its peak were named for Peter D. Mulgrew, a New Zealand adventurer who accompanied Sir Edmund Hillary to the South Pole and served as the chief radio operator at Scott Base. He perished in the Air New Zealand DC10 scenic flight to Ross Island, 28 November 1979, when the airplane crashed near Te Puna Roimata Peak ("spring of tears" peak) on the northeast slope of Mount Erebus, killing all 257 persons aboard.
 Passage 3:The northern segment of the fault runs from Hollister, through the Santa Cruz Mountains, epicenter of the 1989 Loma Prieta earthquake, then up the San Francisco Peninsula, where it was first identified by Professor Lawson in 1895, then offshore at Daly City near Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. The fault returns onshore at Bolinas Lagoon just north of Stinson Beach in Marin County. It returns underwater through the linear trough of Tomales Bay which separates the Point Reyes Peninsula from the mainland, runs just east of Bodega Head through Bodega Bay and back underwater, returning onshore at Fort Ross. (In this region around the San Francisco Bay Area several significant "sister faults" run more-or-less parallel, and each of these can create significantly destructive earthquakes.) From Fort Ross, the northern segment continues overland, forming in part a linear valley through which the Gualala River flows. It goes back offshore at Point Arena. After that, it runs underwater along the coast until it nears Cape Mendocino, where it begins to bend to the west, terminating at the Mendocino Triple Junction.

[EX Q]: Question: Which of the Green family's good friends died first? Passage 1:Thomas was born to Thomas Marston Green Sr., a future Colonel in the Continental Army, and Martha Wills. He was born in Williamsburg, Virginia, on February 26, 1758. In 1782 he moved with his family to Natchez District, Mississippi Territory. He would later move to Fayette, Mississippi where he would build the Springfield Plantation, and where he would live until his death. The Green family were good friends with Andrew Jackson and Rachel Donelson. Thomas's brother Abraham married Elizabeth Caffery who was the niece of Rachel Jackson. In August 1791, Andrew Jackson and Rachel were married at the Green Family Springfield Plantation. The marriage ceremony was performed by Thomas Green Sr., while Thomas Jr. served as a witness. Andrew and Rachel would later find out that Rachel's divorce was not finalized, at the time of the wedding.
 Passage 2:New York played a pivotal role during the American Revolution and subsequent war. The Stamp Act Congress in 1765 brought together representatives from across the Thirteen Colonies to form a unified response to British policies. The Sons of Liberty were active in New York City to challenge British authority. After a major loss at the Battle of Long Island, the Continental Army suffered a series of additional defeats that forced a retreat from the New York City area, leaving the strategic port and harbor to the British army and navy as their North American base of operations for the rest of the war. The Battle of Saratoga was the turning point of the war in favor of the Americans, convincing France to formally ally with them. New York's constitution was adopted in 1777, and strongly influenced the United States Constitution. New York City was the national capital at various times between 1785 and 1790, where the Bill of Rights was drafted. Albany became the permanent state capital in 1797. In 1787, New York became the eleventh state to ratify the United States Constitution.

Eitan assumed responsibility for and resigned over the Jonathan Pollard affair, and the Bureau was disbanded. He was subject to an arrest warrant issued by the United States FBI. From 1985 until 1993, he was head of the government's Chemicals company, which was expanded under his leadership. After 1993, he became a businessman, noted for several large scale agricultural and construction ventures in Cuba.

[EX Q]: Question: What is the birth year of the man whose works Dulfu's thesis dealt with? Passage 1:Born in Tohat, Maramureș County, his parents were Nichifor Dulfu and his wife Agapia (née Bran), members of the rural intellectual class. From early childhood, his mother inspired a love of stories in him. He attended Hungarian-language primary school and gymnasium in Baia Mare from 1864 to 1871, earning top marks, and went to high school in the same town from 1872. In 1876, he graduated from high school in Cluj, where he studied for two years. He attended Franz Joseph University in the latter city, earning a doctorate in philosophy in 1881. His thesis, written in Hungarian, dealt with the work of Vasile Alecsandri, surveyed the Romanian literary context and included a dozen poems translated by Dulfu. After graduation, he moved to the Romanian Old Kingdom and worked as a teacher. After a brief stint in the capital Bucharest, he directed and taught at a school in Turnu Severin for the 1881-1882 year. Beginning in 1882, he again taught philosophy and later Romanian in Bucharest; one of the two schools where he worked was for girls. He came to know faculty colleague Ioan Slavici, as well as Mihail Eminescu, Alexandru Vlahuță and Bogdan Petriceicu Hasdeu. In 1886, he married Elena Mateescu, with whom he had four children and who encouraged his work as a writer. He obtained Romanian citizenship in 1891. During World War I, he worked as a postal censor in the temporary capital of Iași, where an illness claimed one of his daughters. Although normally a disciplined teacher, he lost his composure on December 1, 1918, the day the union of Transylvania with Romania was proclaimed; cutting short the lesson and visibly moved, he explained the significance of the event to his pupils. In 1921, he retired from the girls' school, as the pupils daily reminded him of his deceased daughter.
 Passage 2:Born in Philadelphia and raised in Chicago, Diehl attended MacMurray College in Illinois for two years, after which she married a graduate student at Yale University (since divorced) and moved to New Haven, Connecticut. She returned to Chicago in the early 1970s and began painting among a group of women artists, including Barbara Blades, Liz Langer, Sandra Perlow and Fern Shaffer, studying at the Evanston Art Center with artist Corey Postiglione. Diehl was soon active in the art scene that flourished in Chicago, exhibiting her work at galleries such as Richard Gray, Michael Wyman, Jan Cicero, and N.A.M.E. Gallery, and writing articles and reviews for the New Art Examiner, where she became Managing Editor. She had her first individual exhibition at Roy Boyd Gallery in 1980. During this time, her work was reviewed in the New Art Examiner, the Chicago Sun-Times, the Chicago Tribune, and the Chicago Daily News. In 1976, Diehl moved to New York to work as assistant to John Coplans, then editor of Artforum magazine.
 Passage 3:Born in Hirschberg on the Saale in the Principality of Reuss-Gera, Germany, Mutschmann moved while he was young with his family to Plauen in Saxony. He served an apprenticeship as an embroiderer and from 1896 to 1901 was employed as a master embroiderer, department head and warehouse director in lace and linen factories in Plauen, Herford and Köln. This was followed by military service from 1901-1903, after which he returned to employment in the Plauen Lace Factyory (Plauener Spitzenfabriken). He established his own lace factory, Mutschmann & Eisentraut, in Plauen in October 1907. During World War I, he served on the Western Front until he was severely wounded in April 1916. He was discharged from the Army as unfit for field service on 24 December 1916, then resuming the direction of his factory in Plauen. After the war, he was an early participant in the nationalist and anti-semitic Deutschvölkischer Schutz und Trutzbund. He was a founding member of the local branch (Ortsgruppe) of the National Socialist German Workers Party (NSDAP) in Plauen and made personal donations of capital to the Nazi Party.
