Problem: Background: Irving Grant Thalberg (May 30, 1899 - September 14, 1936) was an American film producer during the early years of motion pictures. He was called "The Boy Wonder" for his youth and ability to select scripts, choose actors, gather production staff, and make profitable films, including Grand Hotel, China Seas, Camille, Mutiny on the Bounty, and The Good Earth. His films carved out an international market, "projecting a seductive image of American life brimming with vitality and rooted in democracy and personal freedom," states biographer Roland Flamini.
Context: He found work as an office secretary at Universal Pictures' New York office, and later became personal secretary to the studio's founder and president, Carl Laemmle. Among Thalberg's duties were transcribing and editing notes that Laemmle had written during screenings of his films. He earned $25 weekly, becoming adept at making insightful observations, which impressed Laemmle. Laemmle took Thalberg to see his Los Angeles production facility, where he spent a month watching how movie production worked. Before returning to New York, Laemmle told Thalberg to remain and "keep an eye on things for me." Two months later, Laemmle returned to California, partly to see how well Thalberg was able to handle the responsibilities he was given. Thalberg gave him suggestions, which impressed Laemmle by his ability to understand and explain problems. Thalberg suggested, "The first thing you should do is establish a new job of studio manager and give him the responsibility of watching day-to-day operations." Laemmle immediately agreed, "All right. You're it." In shock, Thalberg replied, "I'm what?" Laemmle told him to take charge of the Los Angeles studio, which he did in early 1919. At age 20, Thalberg became responsible for immediately overseeing the nine ongoing film productions and nearly thirty scenarios then under development. In describing the rationale for this early appointment as studio manager, film historian David Thomson writes that his new job "owed nothing to nepotism, private wealth, or experience in the film industry." He reasons that despite "Thalberg's youth, modest education, and frail appearance . . . it is clear that he had the charm, insight, and ability, or the appearance of it, to captivate the film world." Thalberg was one among the majority of Hollywood film industry workers who migrated from the East Coast, primarily from New York. Some film actors, such as Conrad Nagel, did not like the 5-day train trip or the sudden warmth of the California climate. Neither did Marion Davies, who was not used to such "big wide spaces." Samuel Marx, a close friend of Thalberg's from New York, recalled how easily Thalberg adapted to Southern California, often standing outside his doorway during moments of contemplation to enjoy the scenery. "We were all young," said comedian Buster Keaton. "The air in California was like wine. Our business was also young--and growing like nothing ever seen before."
Question: How did this help his career?
Answer: Laemmle took Thalberg to see his Los Angeles production facility, where he spent a month watching how movie production worked.

Problem: Background: Barack Hussein Obama II ( ( listen); born August 4, 1961) is an American politician who served as the 44th President of the United States from 2009 to 2017. The first African American to assume the presidency, he was previously the junior United States Senator from Illinois from 2005 to 2008. Before that, he served in the Illinois State Senate from 1997 until 2004. Obama was born in 1961 in Honolulu, Hawaii, two years after the territory was admitted to the Union as the 50th state.
Context: Obama was born on August 4, 1961, at Kapiolani Medical Center for Women and Children in Honolulu, Hawaii. He is the only President who was born in Hawaii and the only President who was born outside of the contiguous 48 states. He was born to a white mother and a black father. His mother, Ann Dunham (1942-1995), was born in Wichita, Kansas; she was mostly of English descent, with some German, Irish, Scottish, Swiss, and Welsh ancestry. His father, Barack Obama Sr. (1936-1982), was a married Luo Kenyan man from Nyang'oma Kogelo. Obama's parents met in 1960 in a Russian language class at the University of Hawaii at Manoa, where his father was a foreign student on scholarship. The couple married in Wailuku, Hawaii on February 2, 1961, six months before Obama was born. In late August 1961 (only a few weeks after he was born), Barack and his mother moved to the University of Washington in Seattle, where they lived for a year. During that time, the elder Obama completed his undergraduate degree in economics in Hawaii, graduating in June 1962. He then left to attend graduate school on a scholarship at Harvard University, where he earned an M.A. in economics. Obama's parents divorced in March 1964. Obama Sr. returned to Kenya in 1964, where he married for a third time. He visited his son in Hawaii only once, at Christmas time in 1971, before he was killed in an automobile accident in 1982, when Obama was 21 years old. Recalling his early childhood, Obama said, "That my father looked nothing like the people around me - that he was black as pitch, my mother white as milk - barely registered in my mind." He described his struggles as a young adult to reconcile social perceptions of his multiracial heritage. In 1963, Dunham met Lolo Soetoro at the University of Hawaii; he was an Indonesian East-West Center graduate student in geography. The couple married on Molokai on March 15, 1965. After two one-year extensions of his J-1 visa, Lolo returned to Indonesia in 1966. His wife and stepson followed sixteen months later in 1967. The family initially lived in a Menteng Dalam neighborhood in the Tebet subdistrict of south Jakarta. From 1970, they lived in a wealthier neighborhood in the Menteng subdistrict of central Jakarta.
