Background: Devika Rani Chaudhuri, usually known as Devika Rani (30 March 1908 - 9 March 1994), was an actress in Indian films who was active during the 1930s and 1940s. Widely acknowledged as the first lady of Indian cinema, Devika Rani had a successful film career that spanned 10 years. Born into a wealthy, anglicized Indian family, Devika Rani was sent to boarding school in England at age nine and grew up in that country. In 1928, she met Himanshu Rai, an Indian film-producer, and married him the following year.
Context: Najm-ul-Hassan was also Devika's co-star in the studio's next venture, Jeevan Naiya. The two co-stars developed a romantic relationship, and during the shooting schedule of Jeevan Naiya, Devika eloped with Hassan. Himanshu was both enraged and distraught. Since the leading pair were absent, production was stalled. A significant portion of the movie had been shot and a large sum of money, which had been taken as credit from financers, had been spent. The studio therefore suffered severe financial losses and a loss of credit among bankers in the city while the runaway couple made merry. Sashadhar Mukherjee, an assistant sound-engineer at the studio, had a brotherly bond with Devika Rani because both of them were Bengalis and spoke that language with each other. He established contact with the runaway couple and managed to convince Devika Rani to return to her husband. In the India of that era, divorce was legally almost impossible and women who eloped were regarded as no better than prostitutes and were shunned by their own families. In her heart of hearts, Devika Rani knew that she could not secure a divorce or marry Hassan under any circumstances. She negotiated with her husband through the auspices of Sashadhar Mukherjee, seeking the separation of her finances from those of her husband as a condition for her return. Henceforth, she would be paid separately for working in his films, but he would be required to single-handedly pay the household expenses for the home in which both of them would live. Himanshu agreed to this, in order to save face in society and to prevent his studio from going bankrupt. Devika Rani returned to her marital home. However, things would never be the same between husband and wife again, and it is said that thenceforth, their relationship was largely confined to work and little or no intimacy transpired between them after this episode. Despite the additional expense involved in re-shooting many portions of the film, Himanshu Rai replaced Najm-ul-Hassan with Ashok Kumar, who was the brother of Sashadhar Mukherjee's wife, as the hero of Jeevan Naiya. This marked the debut, improbable as it may seem, of Ashok Kumar's five-decade-long career in Hindi films. Najm-ul-Hassan was dismissed from his job at Bombay Talkies (this was the period in which actors and actresses were paid regular monthly salaries by one specific film studio and could not work in any other studio). His reputation as a dangerous cad established, he could not find work in any other studio. His career was ruined and he sank into obscurity.
Question: Was their marriage successful?
Answer: In her heart of hearts, Devika Rani knew that she could not secure a divorce or marry Hassan under any circumstances.

Background: Walter Leland Cronkite Jr. (November 4, 1916 - July 17, 2009) was an American broadcast journalist who served as anchorman for the CBS Evening News for 19 years (1962-1981). During the heyday of CBS News in the 1960s and 1970s, he was often cited as "the most trusted man in America" after being so named in an opinion poll. He reported many events from 1937 to 1981, including bombings in World War II; the Nuremberg trials; combat in the Vietnam War; the Dawson's Field hijackings; Watergate; the Iran Hostage Crisis; and the assassinations of President John F. Kennedy, civil rights pioneer Martin Luther King Jr., and Beatles musician John Lennon. He was also known for his extensive coverage of the U.S. space program, from Project Mercury to the Moon landings to the Space Shuttle.
Context: On April 16, 1962, Cronkite succeeded Douglas Edwards as anchorman of the CBS's nightly feature newscast, tentatively renamed Walter Cronkite with the News, but later the CBS Evening News on September 2, 1963, when the show was expanded from 15 to 30 minutes, making Cronkite the anchor of American network television's first nightly half-hour news program. Cronkite's tenure as anchor of the CBS Evening News made him an icon in television news. During the early part of his tenure anchoring the CBS Evening News, Cronkite competed against NBC's anchor team of Chet Huntley and David Brinkley, who anchored the Huntley-Brinkley Report. For much of the 1960s, the Huntley-Brinkley Report had more viewers than Cronkite's broadcast. A key moment for Cronkite came during his coverage of John F. Kennedy's assassination on November 22, 1963. Another factor in Cronkite and CBS' ascendancy to the top of the ratings was that, as the decade progressed, RCA made a corporate decision not to fund NBC News at the levels that CBS provided for its news broadcasts. Consequently, CBS News acquired a reputation for greater accuracy and depth in coverage. This reputation meshed well with Cronkite's wire service experience, and in 1967 the CBS Evening News began to surpass The Huntley-Brinkley Report in viewership during the summer months. In 1969, during the Apollo 11 (with co-host and former astronaut Wally Schirra) and Apollo 13 moon missions, Cronkite received the best ratings and made CBS the most-watched television network for the missions. In 1970, when Huntley retired, the CBS Evening News finally dominated the American TV news viewing audience. Although NBC finally settled on the skilled and well-respected broadcast journalist John Chancellor, Cronkite proved to be more popular and continued to be top-rated until his retirement in 1981. One of Cronkite's trademarks was ending the CBS Evening News with the phrase "...And that's the way it is," followed by the date. Keeping to standards of objective journalism, he omitted this phrase on nights when he ended the newscast with opinion or commentary. Beginning with January 16, 1980, Day 50 of the Iran hostage crisis, Cronkite added the length of the hostages' captivity to the show's closing in order to remind the audience of the unresolved situation, ending only on Day 444, January 20, 1981.
