Background: Dame Agatha Mary Clarissa Christie, Lady Mallowan, (nee Miller; 15 September 1890 - 12 January 1976) was an English writer. She is known for her 66 detective novels and 14 short story collections, particularly those revolving around her fictional detectives Hercule Poirot and Miss Marple. Christie also wrote the world's longest-running play, a murder mystery, The Mousetrap, and six romances under the name Mary Westmacott. In 1971 she was appointed a Dame Commander of the Order of the British Empire (DBE) for her contribution to literature.
Context: Christie had a lifelong interest in archaeology. She met her second husband, Sir Max Mallowan, a distinguished archaeologist, on a trip to the excavation site at Ur in 1930. But her fame as an author far surpassed his fame in archaeology. Prior to meeting Mallowan, Christie had not had any extensive brushes with archaeology, but once the two married, they made sure to only go to sites where they could work together. Christie accompanied Mallowan on countless archaeological trips, spending 3-4 months at a time in Syria and Iraq at excavation sites at Ur, Nineveh, Tell Arpachiyah, Chagar Bazar, Tell Brak, and Nimrud. She wrote novels and short stories, but also contributed work to the archaeological sites, more specifically to the archaeological restoration and labelling of ancient exhibits, including tasks such as cleaning and conserving delicate ivory pieces, reconstructing pottery, developing photos from early excavations which later led to taking photographs of the site and its findings, and taking field notes. Christie would always pay for her own board and lodging and her travel expenses so as to not influence the funding of the archaeological excavations, and she also supported excavations as an anonymous sponsor. During their time in the Middle East, there was also a large amount of time spent travelling to and from Mallowan's sites. Their extensive travelling had a strong influence on her writing, as some type of transportation often plays a part in her murderer's schemes. The large amount of travel was reused in novels such as Murder on the Orient Express, as well as suggesting the idea of archaeology as an adventure itself. After the Second World War, she chronicled her time in Syria with fondness in Come Tell Me How You Live. Anecdotes, memories, funny episodes are strung in a rough timeline, with more emphasis on eccentric characters and lovely scenery than on factual accuracy. From 8 November 2001 to 24 March 2002, The British Museum had an exhibit named Agatha Christie and Archaeology: Mystery in Mesopotamia, which presented the life of Agatha Christie and the influences of archaeology in her life and works.
Question: What other sites did she visit?
Answer: Christie accompanied Mallowan on countless archaeological trips, spending 3-4 months at a time in Syria and Iraq

Background: The fifth Beatle is an informal title that various commentators in the press and entertainment industry have applied to people who were at one point a member of the Beatles, or who had a strong association with the "Fab Four" (John Lennon, Paul McCartney, George Harrison, and Ringo Starr) during the group's existence. The "fifth Beatle" claims first appeared in the press immediately upon the band's rise to global fame in 1963-64. The members have offered their own beliefs of the "fifth Beatle": Lennon was critical of individuals who claimed credit for the Beatles' success, including the individual Beatles themselves, saying in his 1970 interview with Jann Wenner, "I'm not the Beatles. I'm me.
Context: Brian Epstein, the band's manager from 1961 until his death in 1967, was instrumental in the Beatles' rise to global fame. Epstein "discovered" the band in Liverpool, saw their potential, and never wavered in his faith and commitment to them. He purposefully restricted his oversight of the band, limiting himself to business matters and public image, and gave the band free creative rein in their music. Epstein also doggedly sought a recording contract for the band in London at a crucial moment in their career, fighting their perception as provincial "northern" musicians. Epstein's death in essence marked the beginning of the Beatles' dissolution, as Lennon admitted later. Because he was not creatively involved with the band, Epstein was only infrequently called the "fifth Beatle", but over the years he and producer George Martin have clearly been recognised as the inner circle members who most profoundly affected the band's career. In an interview in the 1990s describing Epstein's involvement in the band's rise to fame, Martin declared "He's the fifth Beatle, if there ever was one." McCartney summarized the importance of Epstein to the Beatles when he was interviewed in 1997 for a BBC documentary about Epstein. He stated: "If anyone was the fifth Beatle, it was Brian." In 2013 Epstein was the subject of a graphic novel entitled The Fifth Beatle by Vivek Tiwary. The book was released in November and spent several weeks on The New York Times best-seller list, reaching no. 1 in its third week of release.
