Question: Aleksandr Isayevich Solzhenitsyn (; 11 December 1918 - 3 August 2008) was a Russian novelist, historian, and short story writer. He was an outspoken critic of the Soviet Union and communism and helped to raise global awareness of its Gulag forced labor camp system. He was allowed to publish only one work in the Soviet Union, One Day in the Life of Ivan Denisovich (1962), in the periodical Novy Mir.

During the war, Solzhenitsyn served as the commander of a sound-ranging battery in the Red Army, was involved in major action at the front, and was twice decorated. He was awarded the Order of the Red Star on 8 July 1944 for sound-ranging two German artillery batteries and adjusting counterbattery fire onto them, resulting in their destruction. A series of writings published late in his life, including the early uncompleted novel Love the Revolution!, chronicles his wartime experience and his growing doubts about the moral foundations of the Soviet regime. While serving as an artillery officer in East Prussia, Solzhenitsyn witnessed war crimes against local German civilians by Soviet military personnel. The noncombatants and the elderly were robbed of their meager possessions and women and girls were gang-raped to death. A few years later, in the forced labor camp, he memorized a poem titled "Prussian Nights" about these incidents. In this poem, which describes the gang-rape of a Polish woman whom the Red Army soldiers mistakenly thought to be a German, the first-person narrator comments on the events with sarcasm and refers to the responsibility of official Soviet writers like Ilya Ehrenburg. In The Gulag Archipelago, Solzhenitsyn wrote, "There is nothing that so assists the awakening of omniscience within us as insistent thoughts about one's own transgressions, errors, mistakes. After the difficult cycles of such ponderings over many years, whenever I mentioned the heartlessness of our highest-ranking bureaucrats, the cruelty of our executioners, I remember myself in my Captain's shoulder boards and the forward march of my battery through East Prussia, enshrouded in fire, and I say: 'So were we any better?'"

Problem: Christina Maria Aguilera (born December 18, 1980) is an American singer, songwriter, actress, reality show personality and television personality. Born in Staten Island, New York and raised in Rochester and Wexford, Pennsylvania, she appeared on the television series Star Search and The Mickey Mouse Club in her early years. After recording "Reflection", the theme for Disney's 1998 film Mulan, Aguilera signed with RCA Records. She rose to prominence with her 1999 self-titled debut album that spawned the US Billboard Hot 100 number-one singles "Genie in a Bottle", "What a Girl Wants", and "Come On Over Baby

Christina Maria Aguilera was born in the Staten Island borough of New York City, New York, on December 18, 1980, to Shelly Loraine Kearns (nee Fidler), a musician, and Fausto Xavier Aguilera, a United States Army soldier. Her father is Ecuadorian, while her mother has German, Irish, Welsh, and Dutch ancestry. Her family moved frequently because of her father's military service, and lived in places including New Jersey, Texas, New York, and Japan. Aguilera and her mother alleged that her father was physically and emotionally abusive, claims which he denied; Aguilera used music as a form of escape from her turbulent household. Following her parents' divorce when she was six years old, Aguilera, her younger sister Rachel, and her mother (who later remarried Jim Kearns and gave birth to one more child, Michael 'Mikey' Kearns), moved into her grandmother's home in the Pittsburgh suburb of Rochester, Pennsylvania. After several years of being estranged, Aguilera expressed interest in reconciling with her father in 2012. Growing up, Aguilera, known locally as "the little girl with the big voice", aspired to be a singer, singing in local talent shows and competitions. She won her first talent show at the age of 8, in which she performed Whitney Houston's "I Wanna Dance with Somebody (Who Loves Me)". In 1990, she appeared on Star Search singing "A Sunday Kind of Love", and was eliminated during the semi-final rounds. She later performed the same song during an appearance on Pittsburgh's KDKA-TV's Wake Up with Larry Richert. Throughout her youth in Pittsburgh, Aguilera sang "The Star-Spangled Banner" before Pittsburgh Penguins hockey, Pittsburgh Steelers football, and Pittsburgh Pirates baseball games, in addition to the 1992 Stanley Cup Finals. She attended Rochester Area School District in Rochester and Marshall Middle School near Wexford, and briefly attended North Allegheny Intermediate High School before being home schooled due to bullying. In 1991, Aguilera auditioned for a position on The Mickey Mouse Club, although she did not meet its age requirements. She joined the television series two years later, where she performed musical numbers and sketch comedy until its cancellation in 1994. Her co-stars included Ryan Gosling, Keri Russell, Britney Spears, and Justin Timberlake. When she was fourteen, Aguilera recorded her first song, the duet "All I Wanna Do" with Japanese singer Keizo Nakanishi. She later sent her cover version of Houston's "Run to You" to Walt Disney Pictures in hopes of being selected to record the theme song "Reflection" for their animated film Mulan (1998). "Reflection" peaked at number 19 on the U.S. Billboard Adult Contemporary Chart.
