Q: Question: Who won the Austrian Grand Prix in which Leclerc finished second? Passage: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.

Q: Question: What dates did the secession convention occur in Alabama? Passage:Alabama was central to the Civil War, with the secession convention at Montgomery, birthplace of the Confederacy, inviting other states to form a Southern Republic, during January–March 1861, and develop constitutions to legally run their own affairs. The 1861 Alabama Constitution granted citizenship to current U.S. residents, but prohibited import duties (tariffs) on foreign goods, limited a standing military, and as a final issue, opposed emancipation by any nation, but urged protection of African slaves, with trial by jury, and reserved the power to regulate or prohibit the African slave trade. The secession convention invited all slaveholding states to secede, but only 7 Cotton States of the Lower South formed the Confederacy with Alabama, while the majority of slave states were in the Union and voted to make U.S. slavery permanent by passing the Corwin Amendment, signed by President Buchanan and backed by President Lincoln on March 4, 1861.
