question:
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.

question:
Question: How long had Super Junior been an idol group when they had their six-car accident in Singapore? Passage 1:The Red Line MetroLink alignment begins at Lambert St. Louis International Airport, making stops at the main and east terminal stations. It then proceeds through Kinloch before making a stop in North Hanley near Bel-Ridge. It makes 2 stops (UMSL North & South stations) at the University of Missouri St. Louis located in Normandy. After departing UMSL-North Station, the trains divert south onto the former Wabash/Norfolk & Western Railroad's Union Depot (U.D.) line that once brought passenger trains from Ferguson to Union Station. It further follows into 2 stops in Pagedale on St. Charles Rock Road and Wellston on Plymouth St., before crossing the St. Louis City/County boundary line at Skinker Boulevard; and making a stop at Delmar Boulevard, serving the popular Delmar Loop and located just below the original Wabash Railroad's Delmar Station building. The Red Line meets up with the Blue Line at the Forest Park-DeBaliviere station. From this station to the Fairview Heights station in Illinois, it creates the Shared Alignment track with the Blue Line. It terminates in Shiloh next to the Scott Air Force Base and close to the Mid-America Airport in Mascoutah.
 Passage 2:The Dhoom series began with the release of Dhoom in 2004. The film became a commercial box office hit and received generally positive reviews from audiences, but not so much from critics. As a result, producer Yash Chopra announced plans for a sequel, titled Dhoom 2: Back in Action. John Abraham, portrayer of Kabir Sharma, the villain of the predecessor, was eliminated from the sequel because Chopra did not want Dhoom 2 to repeat the stories featured in its predecessor. Instead, Hrithik Roshan and Aishwarya Rai were introduced into the franchise as the sequel's main villains. Aishwarya Rai's character was summarised as Catwoman, a female fictional comic book femme fatale or anti-hero . Rai stated, "All I can tell you is it would be nothing like anything you've seen me do before." Producer Aditya Chopra told Rai to lose weight after she gained it for her role in 2004's Bride & Prejudice. Yash Chopra stated, "But yes, the role does require Aishwarya to convey oodles of sensuality. She has asked for a couple of months to get into shape. We (at Yash Raj Films) are very clear about every character in every script and what's required of the actors. Before Dhoom, Esha Deol was specifically briefed about the look and the attitude she needed to cultivate. She readily agreed, and look at what Dhoom did to her career!" Roshan also lost twelve pounds of weight at Aditya Chopra's request. With the exception of Abraham and Esha Deol, all of the other main actors in Dhoom were hired again for Dhoom 2.
 Passage 3:There have been a number of car accidents involving Korean idols being followed by sasaeng fans. In 2011, two members of the band Super Junior were caught in a six-car collision after being chased by eight fan vehicles in Singapore. The band members, Leeteuk and Heechul, were unharmed, but Heechul later tweeted that he still suffered after-effects from the accident and was often afraid to drive. In 2013, Seungri, formerly of the band Big Bang, suffered minor injuries in a car accident in Shanghai involving a sasaeng fan. In 2015, Chanyeol of the band Exo wrote on Weibo that he was constantly followed by 20 fan vehicles during a visit to Shanghai.

question:
Question: Did the Battle of Pakchon take place in North Korea or in South Korea? Passage 1:The Battle of Pakchon (5 November 1950), also known as the Battle of Bochuan (), took place ten days after the start of the Chinese First Phase Offensive, following the entry of the Chinese People's Volunteer Army (PVA) into the Korean War. The offensive reversed the United Nations Command (UN) advance towards the Yalu River which had occurred after their intervention in the wake of the North Korean invasion of South Korea at the start of the war. The battle was fought between British and Australian forces from the 27th British Commonwealth Brigade with American armour and artillery in support, and the PVA 117th Division of the 39th Army, around the village of Pakchon on the Taeryong River. After capturing Chongju on 30 October the British and Australians had been ordered to pull back to Pakchon in an attempt to consolidate the western flank of the US Eighth Army. Meanwhile, immediately following their success at Unsan against the Americans, the PVA 117th Division had attacked southward, intending to cut off the UN forces as they withdrew in the face of the unexpected PVA assault. To halt the PVA advance, the 27th British Commonwealth Brigade was ordered to defend the lower crossings of the Taeryong and Chongchon rivers as part of a rearguard, in conjunction with the US 24th Infantry Division further upstream on the right.
