Question: Who won the Austrian Grand Prix in which Leclerc finished second? Passage 1:In China, Leclerc qualified 4th behind Vettel. After overtaking his teammate during the start, he was asked to yield and let Vettel pass. He eventually finished the Chinese Grand Prix in 5th. In Azerbaijan, he was the favourite for pole position until a crash in the second qualifying session ended his contention. He started 8th after penalties for the two Alfa Romeos and finished the race 5th with an extra point for the fastest lap of the race. At the following race in Monaco, he qualified 16th, as part of Ferrari's erroneous strategy that kept him in the garage to save tyres, underestimating track evolution at the end of the qualifying session. He was however promoted to 15th following Antonio Giovinazzi's grid penalty. He overtook Lando Norris and Romain Grosjean but suffered a puncture after a failed attempt to pass the Renault of Nico Hülkenberg. He also suffered severe floor damage to his car, leading to his second retirement at his home race. Leclerc qualified 3rd in Canada, ahead of Daniel Ricciardo in the Renault and behind Lewis Hamilton in the Mercedes. He would finish in the same position, his second podium finish of the season and of his career, behind the controversial 1-2 finish of Hamilton and teammate Sebastian Vettel. He would finish third again in France, having caught up to second-placed Bottas in the closing laps. At the Austrian Grand Prix, he qualified on pole position, the second pole of his Formula 1 career. He subsequently finished second after colliding with Red Bull's Max Verstappen, having led for the major part of the race. The incident was investigated by the stewards after the race, who called it 'a racing incident' and decided against taking action as neither of them was, wholly or predominantly, to blame for the incident.
 Passage 2:The Habeas Corpus Suspension, (1863), entitled An Act relating to Habeas Corpus, and regulating Judicial Proceedings in Certain Cases, was an Act of Congress that authorized the president of the United States to suspend the privilege of the writ of habeas corpus in response to the American Civil War and provided for the release of political prisoners. It began in the House of Representatives as an indemnity bill, introduced on December 5, 1862, releasing the president and his subordinates from any liability for having suspended habeas corpus without congressional approval. The Senate amended the House's bill, and the compromise reported out of the conference committee altered it to qualify the indemnity and to suspend habeas corpus on Congress's own authority. Abraham Lincoln signed the bill into law on March 3, 1863, and suspended habeas corpus under the authority it granted him six months later. The suspension was partially lifted with the issuance of Proclamation 148 by Andrew Johnson, and the Act became inoperative with the end of the Civil War. The exceptions to his Proclamation 148 were the States of Virginia, Kentucky, Tennessee, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, Arkansas, and Texas, the District of Columbia, and the Territories of New Mexico and Arizona.
 Passage 3:The novel provided the basis for a subsequent film version, produced in the Universum Film AG (Ufa) studios. The plot was written by Bobby E. Lüthge and Karl Aloys Schenzinger, the author of the novel. Produced by Karl Ritter, the film was supported by the Nazi leadership and produced for 320,000 reichsmarks under the aegis of Baldur von Schirach. The latter also wrote the lyrics for the Hitler Youth song "Unsere Fahne flattert uns voran", based on an existing melody by Hans-Otto Borgmann, who was also responsible for the music. The director was Hans Steinhoff. For the film, the novel's title was amended with the subtitle Ein Film vom Opfergeist der deutschen Jugend ("A film about the sacrificial spirit of German youth"). The film has a length of 95 minutes (2,605 metres) and was premiered on 11 September 1933 at the Ufa-Phoebus Palace, Munich, and on 19 September at the Ufa-Palast am Zoo, Berlin. It was one of three films about Nazi martyrs in 1933, the other two being SA-Mann Brand and Hans Westmar, and by January 1934 had been viewed by a million people.
