Background: Ambrose was born in Lovington, Illinois, to Rosepha Trippe Ambrose and Stephen Hedges Ambrose. His father was a physician who served in the U.S. Navy during World War II.
Context: Ambrose was the lone historian featured in the 1973-74 ITV television series, The World at War, which detailed the history of World War II. He served as the historical consultant for the movie Saving Private Ryan. Tom Hanks, who starred in the movie, said he "pored over D-Day" and Band of Brothers in researching his role. Hanks also credited Ambrose's books with providing extensive detail, particularly regarding D-Day landings. The HBO mini-series, Band of Brothers (2001), for which he was an executive producer, helped sustain the fresh interest in World War II that had been stimulated by the 50th anniversary of D-Day in 1994 and the 60th anniversary in 2004. Ambrose served as executive producer for Price for Peace, a documentary concerning the war in the Pacific theater during World War II, and for Moments of Truth, a TV documentary containing interviews with World War II veterans. In addition, Ambrose served as a commentator for Lewis & Clark: The Journey of the Corps of Discovery, a documentary by Ken Burns. He provided commentary in twenty made-for TV documentaries, covering diverse topics, such as World War II, Lewis & Clark, and America's prominence in the 20th century. He also appeared as a guest on numerous TV programs or stations, including The Charlie Rose Show, C-Span programming, CNN programming, NBC's Today Show, CNBC's Hardball, and various programming on The History Channel and the National Geographic Channel. Ambrose's association with National Geographic stemmed, in part, from his designation as an Explorer-in-Residence by the Society. In addition to his academic work and publishing, Ambrose operated a historical tour business, acting as a tour guide to European locales of World War II. Also, he served on the board of directors for American Rivers and was a member of the Lewis and Clark Bicentennial Council.

Background: Hamid Karzai , (Pashto/Dari: Hmd khrzy, born 24 December 1957) is an Afghan politician who was the leader of Afghanistan from 22 December 2001 to 29 September 2014, originally as an interim leader and then as President for almost ten years, from 7 December 2004 to 2014. He comes from a politically active family; Karzai's father, uncle and grandfather were all active in Afghan politics and government. Karzai and his father before him, Abdul Ahad Karzai, were each head of the Popalzai tribe of the Durrani tribal confederation.
Context: After winning a democratic mandate in the 2004 election, it was thought that Karzai would pursue a more aggressively reformist path in 2005. However, Karzai has proved to be more cautious than was expected. After his new administration took over in 2004, the economy of Afghanistan began growing rapidly for the first time in many years. Government revenue began increasing every year, although it is still heavily dependent on foreign aid. During the first term in Karzai's Presidency, public discontent grew about corruption and the civilian casualties in the 2001-14. In May 2006, an anti-American and anti-Karzai riot took place in Kabul which left at least seven people dead and 40 injured. In May 2007, after as many as 51 Afghan civilians were killed in a bombing, Karzai asserted that his government "can no longer accept" casualties caused by U.S. and NATO operations. In September 2006, Karzai told the United Nations General Assembly that Afghanistan has become the "worst victim" of terrorism. Karzai said terrorism is rebounding in his country, with militants infiltrating the borders to wage attacks on civilians. He stated, "This does not have its seeds alone in Afghanistan. Military action in the country will, therefore, not deliver the shared goal of eliminating terrorism." He demanded assistance from the international community to destroy terrorist sanctuaries inside and outside Afghanistan. "You have to look beyond Afghanistan to the sources of terrorism," he told the UN General Assembly, and "destroy terrorist sanctuaries beyond" the country, dismantle the elaborate networks in the region that recruit, indoctrinate, train, finance, arm, and deploy terrorists. These activities are also robbing thousands of Afghan children of their right to education, and prevent health workers from doing their jobs in Afghanistan. In addition, he promised to eliminate opium-poppy cultivation in his country, which is possibly helping fuel the ongoing Taliban insurgency. He has repeatedly demanded that NATO forces take more care to avoid civilian casualties when conducting military operations in residential areas. In a September 2006 video broadcast, Karzai stated that if the money wasted on the Iraq War had been actually spent on rebuilding Afghanistan, his country would "be in heaven in less than one year".
Question: What happened after he was elected in 2004?
Answer: Karzai has proved to be more cautious than was expected.

Background: Nelson Piquet Souto Maior (Portuguese pronunciation: ['newso pi'ke], born August 17, 1952), known as Nelson Piquet, is a Brazilian former racing driver and businessman. Since his retirement, Piquet has been ranked among the greatest Formula One drivers in various motorsport polls. Piquet had a brief career in tennis before losing interest in the sport and subsequently took up karting and hid his identity to prevent his father discovering his hobby. He became the Brazilian national karting champion in 1971-72 and won the Formula Vee championship in 1976.
Context: Nelson Piquet and the number 1 went to a stagnating Lotus team in 1988, and his career took a nose dive despite the Camel sponsored Lotus 100T having the same specification Honda V6 turbo that powered the McLarens of Ayrton Senna and Alain Prost. Nelson, who had 20 wins and 3 World Championships following the 1987 season, began to lose his reputation when he had no wins in 1988, losing his number one status to fellow Brazilian Senna, who won 8 races and the championship for McLaren (Prost won 7 races, while Piquet could only manage three 3rd-place finishes for the season). In early 1988 he resorted to using the media to attack his rivals and gained a reputation as an outspoken "loose cannon", such as attacking Mansell and his wife, calling Mansell "an uneducated blockhead" (and insulting his wife's looks), and calling fellow Senna "the Sao Paulo taxi driver" and stating that he "doesn't like women". Piquet retracted his comments when both threatened legal action. He also earned the ire of the Tifosi at the San Marino Grand Prix when he said in an interview with Playboy that Scuderia Ferrari might do better as a team if the boss (Enzo Ferrari) was a younger man instead of the 90-year-old one who rarely attended races due to his age and failing health. Piquet claims he was badly misquoted in the interview, which also had him questioning Alain Prost's standing as the best driver in the world. On the official FIA video review of the 1988 season, Piquet left no doubts that the article got it wrong in his comments about Ferrari (saying that at 90, Enzo Ferrari had to be a strong man to run a Formula One team), and that he considered Prost to be the world's best driver. Piquet had a dismal 1989 season, driving a Judd V8-powered Lotus which had 125 less hp than the Honda V10s used by McLaren. He (and teammate Satoru Nakajima) once again had no wins and they both even failed to qualify for the 1989 Belgian Grand Prix, Piquet's first non-qualification since the 1982 Detroit Grand Prix. On what was his last attempt to qualify at Spa, Piquet lost his chance when he was slowed by rookie Frenchman Olivier Grouillard, who had gained a reputation throughout the season as a blocker.
