[EX Q]: Question: Did Henry and Louisine have any children beside their daughter Electra? Passage 1:William Havemeyer (1770-1851) left Germany at age 15 and arrived in New York City after learning the trade of sugar refining in London. In New York he managed a sugar house on Pine Street before opening his own refinery on Vandam Street with his brother, Frederick Christian Havemeyer, who had come to New York in 1802. Together the two brothers operated the W. & F.C. Havemeyer Company sugar refineries, before passing the business on to their sons. His son William Frederick Havemeyer, retired from the sugar refining business in 1842 and entered politics, eventually serving three terms as Mayor of New York. In 1855 the family relocated their refineries to Brooklyn, where they remained as the business grew to acquire a commanding share of the United States sugar refining market under the leadership of Frederick's grandson, Henry Osborne Havemeyer. The Havemeyer refineries were incorporated as the American Sugar Refining Company in 1891 and became known as Domino Sugar in 1900. In the 20th century several of the family's members made notable contributions to the arts. Henry Osborne Havemeyer and his wife Louisine Havemeyer made large bequests to the Metropolitan Museum of Art and their daughter Electra Havemeyer Webb founded the Shelburne Museum.
 Passage 2:The city is located approximately northwest of the geographic center of South Carolina, and is the primary city of the Midlands region of the state. It lies at the confluence of the Saluda River and the Broad River, which merge at Columbia to form the Congaree River. Columbia is home to the University of South Carolina, the state's flagship university and the largest in the state, and is also the site of Fort Jackson, the largest United States Army installation for Basic Combat Training. Columbia is also located 20 miles west of the site of McEntire Joint National Guard Base, which is operated by the U.S. Air Force and is used as a training base for the 169th Fighter Wing of The South Carolina Air National Guard. Columbia is also the location of the South Carolina State House, which is the center of government for the state. In 1860, the city was the location of the South Carolina Secession Convention, which marked the departure of the first state from the Union in the events leading up to the Civil War.
 Passage 3:The Detroit Lions season was the franchise's 82nd season in the National Football League, their 78th as the Detroit Lions, the 10th playing its home games at Ford Field and the third year under head coach Jim Schwartz.

[EX Q]: Question: What city did Stevens complete a Ph.D. in? Passage 1:The siblings were born in New Haven, Connecticut, and moved to Downey, California, in 1963. Richard took piano lessons as a child, progressing to California State University, Long Beach, while Karen learned the drums. They first performed together as a duo in 1965 and formed the jazz-oriented Richard Carpenter Trio followed by the middle-of-the-road group Spectrum. Signing as Carpenters to A&M Records in 1969, they achieved major success the following year with the hit singles "(They Long to Be) Close to You" and "We've Only Just Begun". Subsequently, the duo's brand of melodic pop produced a record-breaking run of hit recordings on the American Top 40 and Adult Contemporary charts, and they became leading sellers in the soft rock, easy listening and adult contemporary music genres. The Carpenters had three number-one singles and five number-two singles on the Billboard Hot 100 and fifteen number-one hits on the Adult Contemporary chart, in addition to twelve top-10 singles. They have sold more than 90 million records worldwide, making them one of the best-selling music artists of all time. The duo toured continually during the 1970s, which put them under increased strain; Richard took a year off in 1979 after he had become addicted to Quaaludes, while Karen suffered from anorexia nervosa.
 Passage 2: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.
 Passage 3:The 1966 NASCAR season opened at Augusta Speedway on November 14, 1965, with Richard Petty winning the season opening event in a 1965 Plymouth. NASCAR then ventured to Riverside International Raceway where Dan Gurney took the checkered flag in a 1965 Ford. After the January 23rd Riverside event, the drivers and teams traveled to Daytona International Speedway in Florida for the 1966 Daytona 500. Paul Goldsmith and Early Balmer took the qualifying events, while Richard Petty notched his first and only Daytona 500 pole position. Petty came from two laps down during the competition to win by more than a full lap when the race was halted 2 laps shy of scheduled event due to thunderstorms. In March Paul Goldsmith won at Rockingham Speedway, Dick Hutcherson at Bristol, and Jim Hurtubise captured the checkered flag at Atlanta Motor Speedway. Hutcherson's victory at Bristol was by more than 4 laps over the closest competitor, Paul Lewis, when crashes and attrition left only seven cars of the 38 starters running at the end of the Southeastern 500 (now known as Food City 500). On April 3, Pearson finally found his way to victory lane in the first of four consecutive victories at Hickory Motor Speedway. He followed up with wins at Columbia Speedway, Greenville, and Winston-Salem, before Jim Paschal broke his streak at North Wilksboro and repeated at Martinsville Speedway. On May 7, Richard Petty started a string of three consecutive wins at Darlington Raceway, Hampton, and Macon. After Ford's announcement of their boycott of NASCAR on April 7, only 2.500 fans attend the May 13th event in which Darel Dieringer captures the win at Monroe in a contest.

[EX Q]: 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.
