Input: Question: Was Murgescu alive to see the Soviet Union dissolve? Passage 1:Costin Ion Murgescu (; October 27, 1919 August 30, 1989) was a Romanian economist, jurist, journalist and diplomat. A supporter of fascism during his youth, he switched to communism by the end of World War II, and became an editor of the Communist Party daily organ, Romania Libera. He taught at the University of Bucharest and worked for the Economic Research Institute. Having campaigned for multilateralism in world affairs as early as 1944, he helped to distance Romania from the Soviet Union after 1964, and later represented his country at the United Nations. He wrote extensively, publishing works on the effects of land reform and industrialization, on the history of economic thought, and on Romania's relations with the Comecon and the First World.
Passage 2:Elizabeth Alice "Ali" MacGraw (born April 1, 1939) is an American actress, model, author, and animal rights activist. She first gained attention with her role in the film Goodbye, Columbus (1969), for which she won the Golden Globe Award for Most Promising Newcomer. She gained an international profile for her role in the film Love Story (1970), for which she was nominated for an Academy Award for Best Actress and won the Golden Globe Award for Best Actress in a Motion Picture Drama. In 1972, MacGraw was voted the top female box office star in the world and was honored with a hands and footprints ceremony at Grauman's Chinese Theatre after having been in just three films. She went on to star in the popular action films The Getaway (1972) and Convoy (1978) as well as the romantic sports drama Players (1979), the comedy Just Tell Me What You Want (1980), and the historical novel-based television miniseries The Winds of War (1983).

Passage 3:Clarkson has performed the song in eight of her concert tours. First, she performed the song on the Breakaway World Tour, Hazel Eyes Tour, and the Addicted Tour (200506). Later, Clarkson performed the track on the My December Tour (200708). She also performed the song on the 2 Worlds 2 Voices Tour (2008), a co-headlining concert tour with Reba McEntire. It was the first Clarkson song to be performed. Later, she performed the song on the All I Ever Wanted Tour (200910). On the Stronger Tour (2012), Clarkson performed the song as part of a medley, with "The Trouble With Love Is", "How I Feel" and "I Want You". When Clarkson performed the song on her most recent tour, the 12th Annual Honda Civic Tour, where she was a special guest for Maroon 5, she and her music director changed the arrangement to make it sound more jazzy. For her Piece by Piece Tour (2015) Clarkson mashes the song up with "Uptown Funk" by Mark Ronson and Bruno Mars.
