Question: Mwai Kibaki, C.G.H. (born 15 November 1931) is a Kenyan politician who was the third President of Kenya, serving from December 2002 until April 2013. Kibaki was previously Vice-President of Kenya for ten years from 1978 to 1988 under President Daniel arap Moi. He also held cabinet ministerial positions in the Kenyatta and Moi governments, including time as minister for Finance (1969-1981) under Kenyatta, and Minister for Home Affairs (1982-1988) and Minister for Health (1988-1991) under Moi. Kibaki served as an opposition Member of Parliament from 1992 to 2002.

The 2005 Kenyan constitutional referendum was held on 21 November 2005. The main issue of contention in the Constitution review process was how much power should be vested in the Kenyan Presidency. In previous drafts, those who feared a concentration of power in the president added provisions for European-style power-sharing between a ceremonial President elected via universal suffrage and an executive Prime Minister elected by Parliament. The draft presented by the Attorney General Amos Wako for the referendum retained sweeping powers for the Presidency.  Though Kibaki the proposal, some members of his own cabinet, mainly from the LDP wing led by Raila Odinga, allied with the main opposition party KANU to mobilize a powerful NO campaign that resulted in a majority of 58% of voters rejecting the draft.  As a consequence of, and immediately after, the referendum loss, on 23 November 2005, Kibaki dismissed his entire cabinet in the middle of his administration's term, with the aim of purging all Raila-allied ministers from the cabinet. About his decision Kibaki said, "Following the results of the Referendum, it has become necessary for me, as the President of the Republic, to re-organize my Government to make it more cohesive and better able to serve the people of Kenya". The only members of the cabinet office to be spared a midterm exit were the Vice President and Minister of Home Affairs, Moody Awori, and the Attorney General whose position is constitutionally protected. A new cabinet of Kibaki loyalists, including MP's from the opposition, termed the Government of National Unity (GNU), was thereafter appointed, but some MP's who were offered ministerial positions declined to take up posts.  A report by a Kenyan Commission of Inquiry, the Waki Commission, contextualises some issues. They reported that Kibaki, after agreeing to an informal Memorandum of Understanding (MoU) to create the post of Prime Minister, reneged on this pact after being elected. They cite criticism of Kibaki neglecting his pre-election agreement, leaving the public to identify it as an attempt by the Kibaki Government to "keep power to itself rather than share it."

Problem: John William Carson (October 23, 1925 - January 23, 2005) was an American television host, comedian, writer, and producer. He is best known as the host of The Tonight Show Starring Johnny Carson (1962-1992). Carson received six Emmy Awards, the Television Academy's 1980 Governor's Award, and a 1985 Peabody Award. He was inducted into the Television Academy Hall of Fame in 1987.

On May 1, 1972, the show was moved from Thirty Rockefeller Plaza, New York, to Burbank, California, because of the studio's proximity to the celebrities. Carson often joked about "beautiful downtown Burbank" and referred to "beautiful downtown Bakersfield", which prompted Bakersfield Mayor Mary K. Shell to chide Carson and invite him to her city to see improvements made during the early 1980s.  From July 1971, Carson stopped hosting five shows per week. Instead, Mondays featured a guest host, leaving Carson to host the other four weeknights. Shows were videotaped in Burbank at 5:30 pm, fed from there to the Central and Eastern time zone stations via cross-country television line at 8:30 pm Pacific time (11:30 pm Eastern time), and later sent from Burbank to the Pacific time zone stations at 11:30 pm Pacific time. Since only two feeds originated from Burbank, Central time zone stations received the Eastern feed one hour earlier at 10:30 pm local time, and Mountain time stations received the Pacific time zone feed one hour later at 12:30 am local time.  In 1980, at Carson's request, the show cut its 90-minute format to 60 minutes on September 16; Tom Snyder's Tomorrow added a half-hour to fill the vacant time. Joan Rivers became the "permanent" guest host from September 1983 until 1986. The Tonight Show returned to using rotating guest hosts, including comic George Carlin. Jay Leno then became the exclusive guest host in fall 1987. Leno joked that although other guest hosts had upped their fees, he had kept his low, assuring himself more bookings. Eventually, Monday night was for Leno, Tuesday for The Best of Carson--rebroadcasts usually dating from a year earlier, but occasionally from the 1970s.  Although Carson's work schedule became more attenuated, Tonight remained so successful that his compensation from NBC continued to rise; by the mid-1970s, he had become the highest-paid personality on television, earning about $4 million a year ($15,008,000 today), not including nightclub appearances and his other businesses. He refused many offers to appear in films, including title roles in The Thomas Crown Affair and Gene Wilder's role in Blazing Saddles. He also declined director Martin Scorsese's offer to co-star with Robert De Niro in the 1983 film The King of Comedy, the role of a TV talk-show host then going to Jerry Lewis.  In recognition of his 25th anniversary on The Tonight Show, Carson received a personal Peabody Award, the board saying he had "become an American institution, a household word, [and] the most widely quoted American." They also said they "felt the time had come to recognize the contributions that Johnny has made to television, to humor, and to America."
