Problem: Background: Drazen Petrovic (pronounced [draZen petrovitc]; October 22, 1964 - June 7, 1993) was a Croatian professional basketball player. A shooting guard, he initially achieved success playing professional basketball in Europe in the 1980s, before joining the National Basketball Association (NBA) in 1989. A star on multiple stages, Petrovic earned two silver medals and one bronze in Olympic basketball, a gold and a bronze in the FIBA World Cup, a gold and a bronze in the FIBA EuroBasket, and two EuroLeague titles. He represented Yugoslavia's national team and, later, Croatia's national team.
Context: Petrovic's national team debut came at the age of 15, at the Under-18 Balkan Championship in Turkey, where the Yugoslavian junior team won the bronze. The young man regularly played for the Yugoslavian national team in the Balkan Championships, also winning gold with the junior team and silver with the senior team. He also brought back the silver from the 1982 FIBA Europe Under-18 Championship in Bulgaria. The 1984 Summer Olympics were Petrovic's first competition of a grand scale with the Yugoslav senior national team, and the bronze medal won in Los Angeles that summer became his first Olympic medal. Third place was also earned at the 1986 FIBA World Championship, remembered for the last minute thriller in the semi-final game against the Soviet Union. At the 1987 EuroBasket, Petrovic again returned with bronze, as Yugoslavia lost to the hosts and gold medalists Greece. The University Games, held in Zagreb in 1987, saw the Yugoslavian squad with Petrovic win the gold. In the 1988 Summer Olympics, Yugoslavia with Petrovic, earned 2nd place, as they lost once more to the Soviet powerhouse. An excellent club season with Real Madrid was topped by Petrovic's 1989 accomplishment with the Yugoslav national team: at the EuroBasket in Zagreb, the young Yugoslavian team went all the way, defeating Greece more than comfortably in the championship game. Petrovic was the tournament's second leading scorer and most valuable player. The very next year, the summer in between the two most frustrating seasons of his professional career, as he struggled for playing time with the Trail Blazers, Petrovic was again making history with the national team, as Yugoslavia became world champions, after beating the Soviet Union for the gold in Buenos Aires, at the 1990 FIBA World Championship.

Problem: Background: Fred McFeely Rogers (March 20, 1928 - February 27, 2003) was an American television personality, musician, puppeteer, writer, producer, and Presbyterian minister. Rogers was famous for creating, hosting and composing the theme music for the educational preschool television series Mister Rogers' Neighborhood (1968-2001), which featured his kind-hearted grandfatherly personality, and direct connection to his audiences. Originally trained and ordained as a minister, Rogers was displeased with the way television addressed children at the time, and made an effort to change this when he began to write for and perform on local Pittsburgh-area shows dedicated to youth. Rogers developed his own show on WQED in 1968, and it was distributed nationwide by Eastern Educational Television Network.
Context: During the controversy surrounding the introduction of the household VCR, Rogers was involved in supporting the manufacturers of VCRs in court. His 1979 testimony, in the case Sony Corp. of America v. Universal City Studios, Inc., noted that he did not object to home recordings of his television programs, for instance, by families in order to watch them together at a later time. This testimony contrasted with the views of others in the television industry who objected to home recordings or believed that devices to facilitate it should be taxed or regulated. When the case reached the Supreme Court in 1983, the majority decision considered the testimony of Rogers when it held that the Betamax video recorder did not infringe copyright. The Court stated that his views were a notable piece of evidence "that many [television] producers are willing to allow private time-shifting to continue" and even quoted his testimony in a footnote: Some public stations, as well as commercial stations, program the Neighborhood at hours when some children cannot use it ... I have always felt that with the advent of all of this new technology that allows people to tape the Neighborhood off-the-air, and I'm speaking for the Neighborhood because that's what I produce, that they then become much more active in the programming of their family's television life. Very frankly, I am opposed to people being programmed by others. My whole approach in broadcasting has always been "You are an important person just the way you are. You can make healthy decisions." Maybe I'm going on too long, but I just feel that anything that allows a person to be more active in the control of his or her life, in a healthy way, is important.
Question: is he still alive?

Problem: Background: Born in Prague, Czech Republic (then part of the Austro Hungarian empire) Friml showed aptitude for music at an early age. He entered the Prague Conservatory in 1895, where he studied the piano and composition with Antonin Dvorak. Friml was expelled from the conservatory in 1901 for performing without permission.
Context: Friml wrote his most famous operettas in the 1920s. In 1924, he wrote Rose-Marie. This operetta, on which Friml collaborated with lyricists Oscar Hammerstein II and Otto Harbach and co-composer Herbert Stothart, was a hit worldwide, and a few of the songs from it also became hits including "The Mounties" and "Indian Love Call". The use of murder as part of the plot was ground-breaking among operettas and musical theatre pieces at the time. After Rose-Marie's success came two other hit operettas, The Vagabond King in 1925, with lyrics by Brian Hooker and William H. Post, and The Three Musketeers in 1928, with lyrics by P. G. Wodehouse and Clifford Grey, based on Alexandre Dumas's famous swashbuckling novel. In addition, Friml contributed to the Ziegfeld Follies of 1921 and 1923. Friml wrote music for many films during the 1930s, often songs adapted from previous work. The Vagabond King, Rose-Marie and The Firefly were all made into films and included at least some of Friml's music. Oddly enough, his operetta version of The Three Musketeers was never filmed, despite the fact that the novel itself has been filmed many times. In 1930, he wrote a new operetta score for film, The Lottery Bride. Like his contemporary, Ivor Novello, Friml was sometimes ridiculed for the sentimental and insubstantial nature of his compositions and was often called trite. Friml was also criticized for the old-fashioned, Old World sentiments found in his works. Friml's last stage musical was Music Hath Charms in 1934. During the 1930s, Friml's music fell out of fashion on Broadway and in Hollywood.
