Question: How many years apart were Adolphe's half-brother and Adolphe's son? Passage 1:In 1905, Grand Duke Adolphe's younger half-brother, Prince Nikolaus Wilhelm of Nassau, died, having left a son Georg Nikolaus, Count von Merenberg who was, however, the product of a morganatic marriage, and therefore not legally a member of the House of Nassau. In 1907, Adolphe's only son, William IV, Grand Duke of Luxembourg, obtained passage of a law confirming the right of his eldest daughter, Marie-Adélaïde, to succeed to the throne in virtue of the absence of any remaining dynastic males of the House of Nassau, as originally stipulated in the Nassau Family Pact. She became the grand duchy's first reigning female monarch upon her father's death in 1912, and upon her own abdication in 1919, was succeeded by her younger sister Charlotte, who married Felix of Bourbon-Parma, a prince of the former Duchy of Parma. Charlotte's descendants have since reigned as the continued dynasty of Nassau, and also constitute a cadet branch of the House of Bourbon-Parma.
 Passage 2: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 3: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.
