IN: Ai Carina Uemura (Zhi Cun  Ai  karina, Uemura Ai Karina, born November 2, 1981), known mononymously as Ai (Japanese pronunciation: [ai], stylized as AI or A.I. ) is a Japanese-American singer and songwriter who was born in Los Angeles. Ai spent her childhood in both Kagoshima, Japan and Los Angeles. She debuted as a singer in 2000, later moving to Def Jam Japan and rising to fame with her album 2004 Ai.

Ai was born in Los Angeles in 1981. Her father was Japanese and her mother was half Italian-American and half Japanese. She moved to Kagoshima in Japan when she was 4, and went to elementary school and junior high school in Japan.  Ai was motivated to become a singer in her early teens, after singing at a cousin's wedding, having many people ask her if she wanted to be a professional singer, and hearing a gospel performance at the First African Methodist Episcopal Church of Los Angeles in 1993. After graduating from junior high school in Japan, Ai returned to Los Angeles for high school, enrolling at Glendale High School, however found high school difficult due to never formally studying English. After making it through the audition process, she switched to the Los Angeles County High School for the Arts, majoring in ballet. She became a member of the school's gospel choir. In 1998, she performed in a gospel choir at a Mary J. Blige concert at the Universal Amphitheatre, performing of "A Dream." In the same year, she appeared as a dancer in the music video for Janet Jackson's song "Go Deep."  In 1999, she joined an Asian girl group called SX4, who were produced by George Brown of Kool & the Gang. Ai was a member of the group for two years, and later in 1999 the group were offered a record label deal. While on her summer holiday in Kagoshima, she performed Monica's "For You I Will" on a local radio station, which led to her being scouted by BMG Japan. She decided to take the offer, and after leaving SX4 and graduating from high school in June 2000, moved to Tokyo and debuted as a musician later in 2000.
QUESTION: What was Ai doing in the year 1981
IN: Benny was born in Chicago, Illinois, and grew up in nearby Waukegan, Illinois. He was the son of Meyer Kubelsky and Emma Sachs Kubelsky. His parents were Jewish. Meyer was a saloon owner and later a haberdasher who had emigrated to America from Poland.

Benny's comic persona changed over the course of his career. At some point he developed a miserly persona. This stage character was everything that Jack Benny was not: cheap, petty, vain and self-congratulatory. His comic rendering of these traits was the linchpin to the success of his show. Benny set himself up as comedic foil, allowing his supporting characters to draw laughs at the expense of his own flaws. With his humanism and vulnerability in an era where few male characters were allowed such character traits, Benny made what could have been unlikable into an everyman character.  Benny said: "I don't care who gets the laughs on my show, as long as the show is funny." Benny felt he got the credit or blame either way, not the actor saying the lines, so there was emphasis on the comedic bottom line. This attitude reached its apogee in a broadcast structured as a Hollywood bus tour of the stars' homes. Each "stop" on the tour was at a house belonging to one of the show's supporting cast, who would then have a scene which included jokes about the absent Benny. Not until the final moments of the program did the bus arrive at Jack Benny's house, at which point the listening audience heard Benny's only line of the episode: "Driver, here's where I get off." Few stars possessed the combination of daring, humility and comic timing to commit to such an extended payoff.  Mary Livingstone, his wife, was a supporting character, as his wisecracking and not especially deferential female friend. She was not quite his girlfriend, since Benny would often try to date movie stars like Barbara Stanwyck, and occasionally had stage girlfriends, such as "Gladys Zybisco". Don Wilson, the rotund announcer, also appeared on the show. He also announced for Fanny Brice's hit Baby Snooks. Bandleader Phil Harris appeared as a jive talking, alcoholic philanderer whose repartee was profoundly risque for its time. Boy tenor Dennis Day appeared as a sheltered, naive youth who often got the better of his boss. This character was originated by Kenny Baker whom Day replaced. Singer Larry Stevens replaced Dennis Day from November 5, 1944 to March 10, 1946, while the latter served in the Navy.

IN: Richard John Santorum (born May 10, 1958) is an American attorney, author, politician, and CNN Senior Political Commentator. A member of the Republican Party, he served as a United States Senator from Pennsylvania from 1995 to 2007 and was the Senate's third-ranking Republican from 2001 to 2007. He ran as a candidate for the 2012 Republican Party presidential nomination, finishing second to Mitt Romney. Santorum was elected as a United States Senator from Pennsylvania in 1994.

Santorum served in the United States Senate representing Pennsylvania from 1995 to 2007. From 2001 until 2007, he was the Senate's third-ranking Republican. He was first elected to the Senate during the 1994 Republican takeover, narrowly defeating incumbent Democrat Harris Wofford, 49% to 47%. The theme of Santorum's 1994 campaign signs was "Join the Fight!" During the race, he was considered an underdog, as his opponent was 32 years his senior. He was reelected in 2000, defeating U.S. Congressman Ron Klink by a 52-46% margin. In his reelection bid of 2006, he lost to Democrat Bob Casey, Jr. by a 59-41% margin.  After his election to the Senate in 1994, Santorum sought to "practice what [he] preached" and hired five people for his staff who were on welfare, food stamps, or other government aid.  In 1996, Santorum served as Chairman of the Republican Party Task Force on Welfare Reform, and contributed to legislation that became the Personal Responsibility and Work Opportunity Act. Santorum was an author and the floor manager of the bill. In 1996, Santorum endorsed moderate Republican Arlen Specter in his short-lived campaign for president. Reporters have observed that though Santorum and Specter differed on social policy, Specter provided him with key political staff for his successful run in 1994.  The National Taxpayers Union, a fiscal conservative organization, gave Santorum an "A-" score for his votes on fiscal issues, meaning that he was one of "the strongest supporters of responsible tax and spending policies" during his tenure, and ranked fifth in the group's rankings out of 50 senators who served at the same time.
