Question: What was the original name of the Suzba Bezpieczenstwa? Passage:On 30 June 1943 he was arrested by the Gestapo in Warsaw and sent to Berlin. Rowecki was arrested due to his betrayal by Ludwik Kalkstein "Hanka", Eugeniusz Swierczewski "Genes" and Blanka Kaczorowska "Sroka" who were Gestapo agents. All of them were members of the Home Army but in fact collaborated with the Gestapo. Swierczewski, Kalkstein and Kaczorowska were sentenced to death for high treason by the Secret War Tribunal of the Polish Secret State. The sentence on Eugeniusz Swierczewski was carried out by troops commanded by Stefan Rys ("Jozef"). They hanged Swierczewski in the basement of the house at 74 Krochmalna Street in Warsaw. Kalkstein received protection from the Gestapo and was not harmed. He fought in a Waffen SS unit during the Warsaw Uprising of 1944 under the name of Konrad Stark. After the war, he worked for the Polish Radio station in Szczecin and was later recruited as an agent by the Urzad Bezpieczenstwa. In 1982, he emigrated to France; he died in 1994. Blanka Kaczorowska also survived the war. Her death sentence was not carried out because she was pregnant. After the war, she also worked as a secret agent for the Urzad Bezpieczenstwa and later for the renamed Suzba Bezpieczenstwa. She emigrated to France in 1971. She died in 2002

Question: Which of Kuroda's contemporaries had more championships, Hosaka or Tanaka? Passage:Kuroda began his professional wrestling career in January 1993, when he was trained by Pro Wrestling Crusaders (PWC) at their dojo and made his debut on March 18, 1993 against Hideki Hosaka. PWC closed after a few months and Kuroda resumed his training at the Frontier Martial-Arts Wrestling (FMW) dojo. He made his FMW debut as a fan favorite with Masato Tanaka by losing to Dark Ranger and Masaru Toi in a tag team match on October 15. Kuroda remained in the low card for many years in the company and was usually utilized in opening matches on the card and served as a enhancement talent against higher level opponents, winning against only lesser known talent. He was often paired with fellow newcomer Tanaka in mid-card matches during the early years of his career and often wrestled Tanaka, Koji Nakagawa and Gosaku Goshogawara. Kuroda's first main event match took place on November 26, 1994, when he teamed with Atsushi Onita, Katsutoshi Niiyama and Masato Tanaka to defeat Mr. Pogo, The Gladiator, Hideki Hosaka and Hisakatsu Oya in a no ropes barbed wire street fight deathmatch. Kuroda would team with Onita, Niiyama and Tanaka in several street fights during late 1994 and early 1995. In the summer of 1995, Kuroda was entered into the Young Spirit Tournament, a round robin tournament consisting of rising rookies of the company. He would lose all of his matches in the tournament against W*ING Kanemura, Hideki Hosaka, Koji Nakagawa and Hido, while wrestling Masato Tanaka to a double knockout to gain one point in the tournament.

Question: When was the Chicago Tribune founded? Passage:Vincent Canby of The New York Times wrote, "As an attempt to elevate pornography ... into art, it is often witty and funny but it fails for several reasons, including Ginsberg's self-imposed limitations on form (to which he's not completely faithful)." He elaborated that "the screenplay, like the film, eventually drifts in a horizontal direction into a kind of foggy confusion." Variety stated, "The problem with 'Coming Apart' is that while it suggests some interesting ideas, it can't deliver any of them in cogent form. If Torn is supposed to be some form of saint in the 20th Century religion of psychiatry, prepared to accept the truth of his perceptions with detached irony, this only adds to the deadness of the film as public entertainment." Gene Siskel of the Chicago Tribune gave the film 3.5 stars out of 4 and praised Rip Torn for "a brilliantly controlled performance. He never appears to be acting." Kevin Thomas of the Los Angeles Times wrote, "In this dreary study of the disintegration of a New York psychologist (Rip Torn), Ginsberg made the mistake of placing professional actors in improvised Warhol-like situations ... What we're left with, consequently, is scarcely more than some mild but mainly tedious pornography for intellectuals." Gary Arnold of The Washington Post wrote, "Compared to the erotic satire, the film's serious pretensions seem so uninspired and derivative that it's only natural to find that your interest dwindles once the characters start sorting out their souls ... the breakdowns turn morbidly sentimental and theatrically pat." Life reviewer Richard Schickel praised Torn's performance, Ginsberg's inventive use of camera and sound, and the "illuminating" portrayal of a schizophrenic breakdown. Andrew Sarris of The Village Voice gave it a less favorable review, however, and the film was a commercial failure.
