Passage: Stefen "Stef" Djordjevic is a Serbian American high school defensive back who is gifted in both sports and academics. He is seeking a college football scholarship to escape the economically depressed small western Pennsylvania town of Ampipe and a dead-end job and life working at the mill like his father and brother Greg. He dreams of becoming an engineer right after he graduates from college. Ampipe is a company town whose economy is dominated by the town's main employer, American Pipe & Steel, a steel mill struggling through the downturn of the early 1980s recession. Stef gets through his days with the love of his girlfriend, Lisa Lietzke, and his strong bond with his teammates.
Most of the film takes place after the big football game against undefeated Walnut Heights High School. Ampipe appears headed to win the game, when a fumbled handoff in the closing secondsas well as Stefen's pass interference penalty earlier in the gameleads to a Walnut Heights victory. Following the game, Coach Burt Nickerson lambastes the fumbler in the locker room, telling him he "quit" the game. When Stefen retorts that the coach himself quit, the coach kicks him off the team.
In the aftermath, disgruntled Ampipe fans vandalize Coach Nickerson's house and yard. Stefen is present and is a reluctant participant, but is nonetheless seen by Nickerson as the vandals flee. From there, Stefen deals with personal battles, including dealing with the coach blackballing him among colleges because of his attitude and participation in the desecration of Nickerson's yard and house. Stefen gets in an argument with Lisa, and his best friend Brian declines a scholarship offer to USC and plans to marry his pregnant girlfriend.
Question: What's the nickname of the person who gets removed from the team after standing up to the coach?
answer:
Stef.

Passage: In February 2011, Gaga released "Born This Way", the lead single from her studio album of the same name. The song sold more than one million copies within five days, earning the Guinness World Record for the fastest selling single on iTunes. It debuted atop the Billboard Hot 100, becoming the 1,000th number-one single in the history of the charts. Its second single "Judas" followed two months later, and "The Edge of Glory" served as its third single. Both reached the top 10 in the US and the UK. Her music video for "The Edge of Glory", unlike her previous work, portrays her dancing on a fire escape and walking on a lonely street, without intricate choreography and back-up dancers.
Gaga hosted an episode of Saturday Night Live in November 2013, performing "Do What U Want" (with Kelly) and an album cut, "Gypsy". After holding her second Thanksgiving Day television special on ABC, Lady Gaga and the Muppets Holiday Spectacular, she performed a special rendition of "Do What U Want" with Christina Aguilera on the fifth season of the American reality talent show The Voice. In March 2014, Gaga had a seven-day concert residency commemorating the last performance at New York's Roseland Ballroom before its closure. Two months later, she embarked on the ArtRave: The Artpop Ball tour, building on concepts from her ArtRave promotional event. Earning $83 million, the tour included cities canceled from the Born This Way Ball tour itinerary. In the meantime, Gaga split from longtime manager Troy Carter over "creative differences", and by June 2014, she and new manager Bobby Campbell joined Artist Nation, the artist management division of Live Nation Entertainment. She briefly appeared in Rodriguez's Sin City: A Dame to Kill For, and was confirmed as Versace's spring-summer 2014 face with a campaign called "Lady Gaga For Versace".In September 2014, Gaga released a collaborative jazz album with Tony Bennett titled Cheek to Cheek. The inspiration behind the album came from her friendship with Bennett, and fascination with jazz music since her childhood. Before the album was released, it produced the singles "Anything Goes" and "I Can't Give You Anything but Love". Cheek to Cheek received generally favorable reviews; The Guardian's Caroline Sullivan praised Gaga's vocals and Howard Reich of the Chicago Tribune wrote that "Cheek to Cheek serves up the real thing, start to finish". The record was Gaga's third consecutive number-one album on the Billboard 200, and won a Grammy Award for Best Traditional Pop Vocal Album. The duo recorded the concert special Tony Bennett and Lady Gaga: Cheek to Cheek Live!, and embarked on the Cheek to Cheek Tour from December 2014 to August 2015.
Question: What is the title of the album before whose release it produced the singles "Anything Goes" and "I Can't Give You Anything but Love"?
answer:
Cheek to Cheek.

Passage: The Night of the Long Knives (German: Nacht der langen Messer ), or the Rohm Purge, also called Operation Hummingbird (German: Unternehmen Kolibri), was a purge that took place in Nazi Germany from June 30 to July 2, 1934, when Adolf Hitler, urged on by Hermann Goring and Heinrich Himmler, carried out a series of political extrajudicial executions intended to consolidate his hold on power in Germany, as well as to alleviate the concerns of the German military about the role of Ernst Rohm and the Sturmabteilung (SA), the Nazis' own mass paramilitary organization. Nazi propaganda presented the murders as a preventive measure against an alleged imminent coup by the SA under Rohm the so-called Rohm putsch.
The primary instruments of Hitler's action, who carried out most of the killings, were the Schutzstaffel (SS) paramilitary force under Himmler and its Security Service (SD) under Reinhard Heydrich, and the Gestapo, the secret police, under Goring. Goring's personal police battalion also took part in the killings. Many of those killed in the purge were leaders of the SA, the best-known being Rohm himself, the SA's chief of staff and one of Hitler's longtime supporters and allies. Leading members of the leftist-leaning Strasserist faction of the Nazi Party, including its figurehead, Gregor Strasser, were also killed, as were establishment conservatives and anti-Nazis, such as former Chancellor Kurt von Schleicher and Bavarian politician Gustav Ritter von Kahr, who had suppressed Hitler's Munich Beer Hall Putsch in 1923. The murders of SA leaders were also intended to improve the image of the Hitler government with a German public that was increasingly critical of thuggish SA tactics.
Question: What is the first name of the person who the SA was under during an alleged imminent coup?
answer:
Ernst.
