input: In 1987, Clemons was drafted by the Kansas City Chiefs of the National Football League. During the 1987 NFL season, Clemons played in eight games, predominantly as a punt returner, where he collected 19 returns for 162 yards. When Clemons first joined the Toronto Argonauts in 1989, guest running backs coach Tom Cudney nicknamed him "Pinball" because of his running style. His diminutive size and extraordinary balance allowed him to bounce between defensive players much like a pinball inside a pinball machine. During home games, The Who song "Pinball Wizard" would play on the P.A. each time Clemons was involved in a great play. In his first game with the Argonauts, Clemons was named the player of the game. In 1990, Clemons received the CFL's Most Outstanding Player Award after setting a single season record for all-purpose yards (3,300). The following year, Clemons won his very first football championship as his Argonauts defeated the Calgary Stampeders to win the Grey Cup. Clemons went on to win two more Grey Cups as a player when Doug Flutie led Argonauts won back-to-back titles during the 1996 & 1997 seasons. In 1997, Clemons surpassed his own single season all-purpose yards record from 1990 by recording 3,840 all-purpose yards. This mark stood until 2012, when it was broken by Chad Owens. On September 15, 2000, Clemons played his last ever game as an Argonaut. During his 12-year playing career with the Argonauts he set many team records including career pass receptions (682), punt return yards (6,025), punt returns (610), punt return touchdowns (8), kickoff return yards (6,349), and kickoff returns (300). He also set single season single-season punt return yards (1,070 in 1997), punt returns (111 in 1997), and kickoff returns (49 in 1997). Clemons also amassed a career 25,438 combined yards during the regular season, a CFL record. In 2008, Clemons was inducted into the Canadian Football Hall of Fame.

Problem: Background: Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.
Context: In 1947, Salk became ambitious for his own lab and was granted one at the University of Pittsburgh, but the lab was smaller than he had hoped and he found the rules imposed by the university restrictive. In 1948, Harry Weaver, the director of research at the National Foundation for Infantile Paralysis, contacted Salk. He asked Salk to find out if there were more types of polio than the three then known, offering additional space, equipment and researchers. For the first year he gathered supplies and researchers including Julius Youngner, Byron Bennett, L. James Lewis, and secretary Lorraine Friedman joined Salk's team, as well. As time went on, Salk began securing grants from the Mellon family and was able to build a working virology laboratory. He later joined the National Foundation for Infantile Paralysis's polio project established by President Franklin D. Roosevelt. Extensive publicity and fear of polio led to much increased funding, $67 million by 1955, but research continued on dangerous live vaccines. Salk decided to use the safer 'killed' virus, instead of weakened forms of strains of polio viruses like the ones used contemporarily by Albert Sabin, who was developing an oral vaccine. After successful tests on laboratory animals, on July 2, 1952, assisted by the staff at the D.T. Watson Home for Crippled Children, Salk injected 43 children with his killed-virus vaccine. A few weeks later, Salk injected children at the Polk State School for the retarded and feeble-minded. In 1954 he tested the vaccine on about one million children, known as the polio pioneers. The vaccine was announced as safe on April 12, 1955. The project became large, involving 100 million contributors to the March of Dimes, and 7 million volunteers. The foundation allowed itself to go into debt to finance the final research required to develop the Salk vaccine. Salk worked incessantly for two and a half years. Salk's inactivated polio vaccine was the first vaccine for the disease; it came into use in 1955. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.
Question: When did Salk do polio research?
Answer: In 1948,

Question: Anita Mui Yim-fong (Chinese: Mei Yan Fang ; Jyutping: Mui4 Jim6 Fong1; 10 October 1963 - 30 December 2003) was a Hong Kong singer and actress making major contributions to the Cantopop music scene and receiving numerous awards and honours.

On 5 September 2003, Mui publicly announced that she had cervical cancer, from which her sister had also died. She held a series of eight shows at the Hong Kong Coliseum from 6-11 November and 14-15 November 2003, which were to be her last concerts before her death. Her symbolic act was to "marry the stage", which was accompanied by her hit song "Sunset Melody" (Xi Yang Zhi Ge ) as she exited the stage. The last song she performed on stage was "Cherish When We Meet Again" (Zhen Xi Zai Hui Shi ), a rendition of The Manhattans' "Let's Just Kiss And Say Goodbye" on 15 November 2003, where she was accompanied by her friends on the stage. She eventually succumbed to cervical cancer and died of respiratory complications leading to lung failure at Hong Kong Sanatorium and Hospital on 30 December 2003 at 02:50 (HK local time). She was 40 years old. Thousands of fans turned out for her funeral at North Point in January 2004. In 1998, an ATV-produced television series Forever Love Song told a story of a character which was loosely based on that of Mui, but the character names were purposely changed. In 2007, a television series was produced in China titled Anita Mui Fei (Mei Yan Fang Fei ) to tell the story of her life. The 42-episode series was broadcast by China Education Television. Some subjects, such as her suffering from cancer, Leslie Cheung's suicide. and her mother's real estate dilemma, were avoided. Alice Chan (Chen Wei ) portrayed Mui in the series. On 11 October 2008, a show on TVB, titled Our Anita Mui (Wo Men De Mei Yan Fang ), was dedicated to Mui. Many fans and off-stage personnel who worked with her had a chance to talk about their personal experiences with Mui. Singers who participated in the show included Andy Hui, Edmond Leung, and Stephanie Cheng. Mui was cremated and her ashes are interred at the Po Lin Monastery's mausoleum on Lantau Island. On 18 July 2014, a statue of Anita Mui was unveiled on Hong Kong's Avenue of Stars.
