Question: Who was the main author of the Magna Carta? Passage:During the 24 November 1999 Parliamentary debate on the rule of law, Jeyaretnam traced the doctrine to the Magna Carta, and said that it was to be found in the Constitution of Singapore, particularly in Article 9 and Article 12, which respectively protect the rights to life and personal liberty, and equality rights. He also noted that in the court judgment Ong Ah Chuan v Public Prosecutor (1980), the Privy Council had held that in phrases such as "in accordance with law" and "equality before the law" in the Constitution, the term law does not only mean Acts passed by Parliament, but also includes the fundamental rules of natural justice that have been accepted and become part and parcel of the common law. He then cited eight instances of the Government's alleged non-compliance with the rule of law, including detention without trial under, inter alia, the ISA and the Criminal Law (Temporary Provisions) Act ("CLTPA"); denial of the right of arrested persons to counsel and to visits from their families for a period of time; denial of the rights to freedom of speech and assembly; and the tendency of the executive not to provide reasons for decisions made. Opposition MP Chiam See Tong complained that the Government had not treated opposition parties fairly as regards applications for licences for events.

Question: Which team did Ferby lose to in the semi-finals of the 2001 Worlds? Passage:In 1999, Rycroft left the team to play with Ferbey's main rival, Kevin Martin. Rycroft was replaced by Marcel Rocque. The Ferbey Four that would dominate the Brier for the next few years was complete. Ferbey made his return to the Alberta provincials in 1999. While they didn't win, they did return in 2001 with a bang. They went on to winning not only the Alberta championship, but the 2001 Nokia Brier as well beating Kerry Burtnyk of Manitoba 8–4 in the final. This sent the team to the 2001 Worlds where they lost both their semi-final game and the bronze medal game, which they gave up to Pål Trulsen of Norway. In 2002, Ferbey won his fourth Brier, the 2002 Nokia Brier, which was his team's 2nd. They beat John Morris 9–4 in the final. This time, at the 2002 Worlds in Bismarck, North Dakota his team won the championship, beating the same Pål Trulsen, 10–5. Ferbey and his team would return to the Brier, at the 2003 Nokia Brier in Halifax, Nova Scotia. In the finals, they beat the home-town favourites Mark Dacey 8–4 in the finals. At the 2003 Ford World Curling Championship, his team won their 2nd world title, beating Ralph Stöckli of Switzerland 10–6 in the finals. The 2004 Nokia Brier was a blip on his team's record. After returning to the Brier for the fourth straight year, an unprecedented feat especially considering the great number of good teams in Alberta, his team would bow out in the final. After a 10–1 round-robin record, Ferbey and his team lost out to the same team they beat the previous year, Mark Dacey of Nova Scotia, in a 10–9 game where Ferbey's team surrendered a lead. However, Team Ferbey did not give up, and their reign would not be over. In 2005, the once again won the Alberta championships, and once again won the 2005 Canadian championships. This set a record, as his team became the first to win 4 championships as a team. The final was against Nova Scotia again, albeit a different team, that of Shawn Adams. In another close game, team Ferbey pulled it out and won 5–4 in the final. His trip to the 2005 Men's Ford World Curling Championships were marked with struggles, as the team finished the round-robin with three losses – tied for first with five other teams. After having a 4–3 record, Ferbey mounted eight straight wins to win the championship over David Murdoch of Scotland in a convincing 11–4 victory. Additionally, the Ferbey rink was the first team in history to score five on any single end in the world finals – and they managed this feat twice at the 2005 Ford World Curling Championships.

Question: Who defeated West Germany to win the 1976 final? Passage:Following the end of World War II, Germany was partitioned into rival West and East zones, each with their own football systems. The general turmoil of the period and the country's lack of international footballing pedigree up to that point meant it was a surprise to many when West Germany won the 1954 FIFA World Cup in neighbouring Switzerland. It was in the mid-1960s when German football became very strong, with the backbone of the national squad formed by an exceptional group of young players at FC Bayern Munich, soon augmented further by another very strong team at Borussia Monchengladbach and others from the leading clubs. After reaching the 1966 FIFA World Cup Final, they built on victory in UEFA Euro 1972 by winning the 1954 FIFA World Cup on home soil. A further Euro win in 1980 (after an unexpected loss in the 1976 final), plus further World Cup final appearances in 1982 and 1986 confirmed their status as one of the world's most consistently powerful teams. With the end of the Cold War and reunification of the country approaching at the end of the 1980s, the final achievement of West Germany was winning the 1990 FIFA World Cup.
