[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 Top40 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 Hot100 and fifteen number-one hits on the Adult Contemporary chart, in addition to twelve top-10 singles. They have sold more than 90million 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.

Passage 2:A Thorn for Every Heart was started in early 2003 by Joel Ryan Holt (guitar) and Aaron Peck (drums). The original line-up of Holt, Peck, Kelvin Cruz (lead vocals), Jeff Harber (guitar, keys, backing vocals), Justin Powell (bass), and Joy Welling (violin) independently released their debut EP, Silence Is Golden, in late 2003. The EP gained them internet exposure and created an underground following, leading to talks of a record deal with Interscope. Due to musical differences, Holt (guitar/band co-founder) and ATFEH parted ways, and long-time friend Phil Nguyen joined the band in Holt's place. In support of the EP, ATFEH embarked on their first nationwide tour in 2004, during which Welling (violin) parted ways with the band due to personal differences. The band never replaced the violinist or added any other full-time instruments to the group's sound. ATFEH recorded their first full-length album, Things Aren't So Beautiful Now, with producer Shawn Sullivan (Bleeding Through, Reel Big Fish) in the summer of 2004. The album, featuring five reworked songs from the EP and five new songs, was released on October 19, 2004, through Interscope's subsidiary, Kickball Records. After recording the album, Peck (drums/band co-founder) also parted ways with the band, leaving the permanent drummer position open for a year afterward.
Passage 3:He was a member of the Irish Volunteers and on the outbreak of the 1916 Easter Rising he walked the 26 kilometres to Dublin to fight in the Rising. He was imprisoned in the mass arrests and deportations that followed, and released in 1917. Like many Rising survivors, he joined Sinn Fein, a small separatist party that was wrongly blamed by the British government for the Easter Rising. In the aftermath of the Rising, survivors led by Eamon de Valera took over the party in the struggle for the establishment of an Irish republic. Ua Buachalla was elected as a Sinn Fein MP for Kildare North at the 1918 general election. He served in the First Dail (19181921), and was re-elected to the Second Dail in 1921 as a Teachta Dala (TD) for KildareWicklow. He sided with de Valera and opposed the Anglo-Irish Treaty. He fought in the Four Courts in the Civil War. Imprisoned in Dundalk jail, he was released by the Anti-Treaty troops in August 1922. He lost his seat at the 1922 general election, and was an unsuccessful candidate at the 1923 general election.

[EX Q]: Question: In what city is the university where Beloff traveled to in 1946 to perform research? Passage 1:Anne Beloff was born in 1921 in Hampstead to Simon Beloff and Marie Katzin. Her parents were of RussianJewish background, and her siblings included the historian Max Beloff, Baron Beloff, the psychologist John Beloff, the journalist Nora Beloff, and the politician Renee Soskin. She earned a degree in chemistry from University College London in 1942 before completing a PhD in the biochemistry of skin burns with Rudolph Peters at the University of Oxford. She visited Harvard Medical School in 1946 to perform research and returned to the UK in 1948. In the same year she married Ernst Boris Chain, a biochemist who had won the Nobel Prize in Physiology or Medicine in 1945, and moved with him to Rome.
Passage 2:Bieberbach wrote a habilitation thesis in 1911 about groups of Euclidean motions identifying conditions under which the group must have a translational subgroup whose vectors span the Euclidean space that helped solve Hilbert's 18th problem. He worked on complex analysis and its applications to other areas in mathematics. He is known for his work on dynamics in several complex variables, where he obtained results similar to Fatou's. In 1916 he formulated the Bieberbach conjecture, stating a necessary condition for a holomorphic function to map the open unit disc injectively into the complex plane in terms of the function's Taylor series. In 1984 Louis de Branges proved the conjecture (for this reason, the Bieberbach conjecture is sometimes called de Branges' theorem). There is also a on space groups. In 1928 Bieberbach wrote a book with Issai Schur titled Uber die Minkowskische Reduktiontheorie der positiven quadratischen Formen.
Passage 3:Sherwood later began taking acting lessons and landed a guest role on the TV sitcom My Wife and Kids. In 2003, she was cast in the short lived series Platinum as the feisty Jade Rhames alongside Sticky Fingaz and Jason George.
