In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
One example: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage 1: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lô during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
. Passage 2: John Ford (1894–1973) was an American film director whose career spanned from 1913 to 1971. During this time he directed more than 140 films. Born in Maine, Ford entered the filmmaking industry shortly after graduating from high school with the help of his older brother, Francis Ford, who had established himself as a leading man and director for Universal Studios. After working as an actor, assistant director, stuntman, and prop man – often for his brother – Universal gave Ford the opportunity to direct in 1917. Initially working in short films, he quickly moved into features, largely with Harry Carey as his star. In 1920 Ford left Universal and began working for the Fox Film Corporation. During the next ten years he directed more than 30 films, including the westerns The Iron Horse (1924) and 3 Bad Men (1926), both starring George O'Brien, the war drama Four Sons and the Irish romantic drama Hangman's House (both 1928 and both starring Victor McLaglen). In the same year of these last two films, Ford directed his first all-talking film, the short Napoleon's Barber. The following year he directed his first all-talking feature, The Black Watch.
. Passage 3: Since the late 1970s, the central part of NYU is its Washington Square campus in the heart of Greenwich Village. Despite being public property, and expanding the Fifth Avenue axis into Washington Square Park, the Washington Square Arch is the unofficial symbol of NYU. Until 2008, NYU's commencement ceremony was held in Washington Square Park. However, due to space constraints, ceremonies are now held at the Yankee Stadium. Important facilities at Washington Square are the Elmer Holmes Bobst Library, designed by Philip Johnson and Richard Foster, who also designed several other structures, such as Tisch Hall, Meyer Hall, and the Hagop Kevorkian Center. When designing these buildings Johnson and Foster also set up a master plan for a complete redesign of the NYU Washington Square campus. However, it was never implemented. Other historic buildings include the Silver Center (formerly known as "Main building"); the Brown Building of Science; Judson Hall, which houses the King Juan Carlos I of Spain Center; Vanderbilt Hall, the historic townhouse row on Washington Square North; The Grey Art Gallery at 100 Washington Square East, housing the New York University art collection and featuring museum quality exhibitions; the Kaufman Management Center; and the Torch Club – the NYU dining and club facility for alumni, faculty, and administrators. Just a block south of Washington Square is NYU's Washington Square Village, housing graduate students and junior and senior faculty residences in the Silver Towers, designed by I. M. Pei, where an enlargement of Picasso's sculpture Bust of Sylvette (1934) is displayed.

Explanation: The question refers to the 704th unit and task about war which is decribed by Passage 1.

Now, solve this: Question: What was the name of father of the historian who said Constantine was ranked sebastos? Passage 1:SR 510 begins as Marvin Road at exit 111, a diamond interchange on (I-5) in southern Lacey. The highway travels south by the Hawks Prairie Village Mall, home of the Hawks Prairie Center, a division of the South Puget Sound Community College. South of the mall is the Martin Way intersection, located west of River Ridge High School and one of the busiest intersections on the roadway at a daily average of 24,000 motorists in 2008, and the Pacific Avenue roundabout, where SR 510 turns east, renamed Pacific Avenue, northeast of Long Lake. After leaving Lacey city limits, the roadway begins to parallel the Quadlok line owned by Tacoma Rail south towards the Old Pacific Highway. At the Old Pacific Highway, the road becomes the St. Clair Cutoff Road, named for nearby Saint Clair Lake, and crosses the railroad tracks twice. After turning northeast, parallel to Saint Clair Lake's shoreline, the highway dips southeast, now parallel to the Nisqually River, into Fort Lewis and the Nisqually Indian Community. Outside of the community, SR 510 is renamed the Yelm Highway and passes Southworth Elementary. After intersecting Mudd Run Road, future western terminus of the Yelm Loop, the roadway enters Yelm city limits. After turning southeast, SR 510 becomes Yelm Avenue and serves Yelm High School. Shortly thereafter, the roadway serves Yelm Middle School, crosses the Yelm-Tenino Trail, a long rail trail in operation since 1993, and ends at First Street, signed as , which continues southeast as Yelm Avenue.
 Passage 2:Martha Hyer was born in Fort Worth, Texas into a wealthy family, the daughter of Julien Capers Hyer (1894–1974), an attorney and judge, and Agnes Rebecca (née Barnhart; 1892–1969). She was the middle of three sisters, with Agnes Ann (1920–2014) and Jeanne (b. 1928). The Hyers were active in the Methodist church where her father was a highly respected Sunday school teacher. Hyer graduated from Arlington Heights High School and then from Northwestern University with a degree in drama. She was in the sorority Pi Beta Phi with actress Patricia Neal. She then moved to California to study at the Pasadena Playhouse, and soon after was signed to a film contract with RKO. She was married twice, first to producer C. Ray Stahl and later to producer Hal B. Wallis. She converted to Judaism, Wallis's religion, after their marriage. Wallis and Hyer remained together until his death in 1986. Hyer and Wallis contributed funds towards the construction of “The Hal and Martha Hyer Wallis Theatre”, a black box theater, at Northwestern University. She had no children.
 Passage 3:A member of the Aspietes family, of noble Armenian origin, Constantine was probably a close relative of his contemporary Michael Aspietes, a distinguished general killed in 1176. Like his relative, Constantine too had earned distinction during Manuel I Komnenos' campaign against the Hungarians in 1167. The historian John Kinnamos records that he held the rank of sebastos. He is next recorded as being active in 1190/1, during the Byzantine efforts to suppress the Bulgarian–Vlach rebellion of the brothers Peter and Ivan Asen. The historian Niketas Choniates records that, in an effort to sustain the troops and bolster their morale, Aspietes decided to distribute to them their delayed annual salaries. This act, however, enraged Emperor Isaac II Angelos, who saw in it almost an attempt to bribe the army to support Aspietes in overthrowing him. The emperor had Aspietes arrested and blinded, after which nothing further is known of him. He possibly died in the early years of the 13th century.
