Example Input: Question: How many episodes did Case's character appear in on General Hospital? Passage:In November 1989, Case scored her first television role playing Dawn Winthrop on the ABC Network soap opera General Hospital. Case wanted to "perfect" her audition prior to screen testing as Dawn, who served as the long-lost daughter of the long-running character Monica Quartermaine (Leslie Charleson). Speaking of the audition, Case stated: "I practiced night and day [...] It was a heavy scene in which Dawn learned that her boyfriend Ned (Kurt Robin McKinney) had once slept with her mother! I knew I had to do the best job [possible]". She departed General Hospital the next year, after a guest appearance on another ABC series, the comedy drama Doogie Howser, M.D.. In 1991, Case appeared in various other television series, including Diplomatic Immunity, Beverly Hills, 90210, Parker Lewis Can't Lose and Cheers. From November 1992 to 1993 Case stepped into her second soap opera role, as Debbie Simon on the CBS Network drama As the World Turns. Case has stated that she loved the role, and wanted to stay on to explore more into the character of Debbie who was a "manic depressive", an issue that hadn't been covered on daytime television. During this, she also appeared on the CBS crime drama Silk Stalkings as Bonnie Abagail. In 1994, a year after departing from As the World Turns, she became a regular on the primetime soap opera Valley of the Dolls, which was based on the romantic novel of the same name. In 1997, Case had a role in the HBO film Breast Men. Previously, she turned down a larger role in the film due to being uncomfortable topless on-screen. Instead, she accepted a smaller, clothed role.

Example Input: Question: What sport was broadcast from Wrigley Field? Passage:Telstar 1 relayed its first, and non-public, television pictures—a flag outside Andover Earth Station—to Pleumeur-Bodou on July 11, 1962. Almost two weeks later, on July 23, at 3:00 p.m. EDT, it relayed the first publicly available live transatlantic television signal. The broadcast was shown in Europe by Eurovision and in North America by NBC, CBS, ABC, and the CBC. The first public broadcast featured CBS's Walter Cronkite and NBC's Chet Huntley in New York, and the BBC's Richard Dimbleby in Brussels. The first pictures were the Statue of Liberty in New York and the Eiffel Tower in Paris. The first broadcast was to have been remarks by President John F. Kennedy, but the signal was acquired before the president was ready, so engineers filled the lead-in time with a short segment of a televised game between the Philadelphia Phillies and the Chicago Cubs at Wrigley Field. The batter, Tony Taylor, was seen hitting a ball pitched by Cal Koonce to the right fielder George Altman. From there, the video switched first to Washington, DC; then to Cape Canaveral, Florida; to the Seattle World's Fair; then to Quebec and finally to Stratford, Ontario. The Washington segment included remarks by President Kennedy, talking about the price of the American dollar, which was causing concern in Europe. When Kennedy denied that the United States would devalue the dollar it immediately strengthened on world markets; Cronkite later said that "we all glimpsed something of the true power of the instrument we had wrought."
