[Q]: Question: How long had 20th Centuy Fox been established when they signed Holm to a movie contract? Passage:After she starred in the Broadway production of Bloomer Girl, 20th Century Fox signed Holm to a movie contract in 1946. She made her film debut that same year in Three Little Girls in Blue, making a startling entrance in a "Technicolor red" dress singing "Always a Lady," a belting Ado Annie-type song, although the character was different—a lady. In 1947 she won an Oscar and Golden Globe for Best Supporting Actress in Gentleman's Agreement. However, after another supporting role in All About Eve, Holm realized she preferred live theater to movie work, and only accepted a few select film roles over the next decade. The most successful of these were the comedy The Tender Trap (1955) and the musical High Society (1956), both of which co-starred Frank Sinatra. She starred as a professor-turned-reporter in New York City in the CBS television series Honestly, Celeste! (fall 1954) and was thereafter a panelist on Who Pays? (1959). She also appeared several times on ABC's The Pat Boone Chevy Showroom.

[Q]: Question: How often are new issues of the Canadian Journal of Neurological Sciences published? Passage:Multi-dose versions of the vaccine contain the preservative thiomersal (also known as thimerosal), a mercury compound that prevents contamination when the vial is used repeatedly. Single-dose versions and the live vaccine do not contain this preservative. In the U.S., one dose from a multi-dose vial contains approximately 25 micrograms of mercury, a bit less than a typical tuna fish sandwich. In Canada, different variants contain five and 50 micrograms of thimerosal per dose. The use of thiomersal has been controversial, with claims that it can cause autism and other developmental disorders. The U.S. Institute of Medicine examined these claims and concluded in 2004 that the evidence did not support any link between vaccines and autism. Other reviews came to similar conclusions, with a 2006 review in the Canadian Journal of Neurological Sciences stating that there is no convincing evidence to support the claim that thimerosal has a causal role in autism, and a 2009 review in the journal Clinical Infectious Diseases stating that claims that mercury can cause autism are "biologically implausible". The U.K. National Health Service stated in 2003 that "There is no evidence of long-term adverse effects due to the exposure levels of thiomersal in vaccines." The World Health Organization concluded that there is "no evidence of toxicity in infants, children or adults exposed to thiomersal in vaccines". Indeed, in 2008 a review noted that even though thiomersal was removed from all US childhood vaccines in 2001, this has not changed the number of autism diagnoses, which are still increasing.
