instruction:
In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

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.

Question: What was Hungary's record in the 1958 World Cup? Passage:Budai made his debut for Hungary on 2 May 1949 in a 6-1 win against Austria in the Central European Championship. He subsequently played 39 times for Hungary and scored 10 goals. Four of these goals came in a 12-0 win against Albania on 24 September 1950. As one of the legendary Mighty Magyars, he helped Hungary become Olympic Champions in 1952 and Central European Champions in 1953. He also played in the Hungary side that defeated England 6-3 at Wembley Stadium. During the 1954 FIFA World Cup he played in the group stage in the 9-0 win against South Korea and in the semi-final against Uruguay. However, despite an excellent performance in the latter game, he was dropped for the final to make room for Ferenc Puskas. He also played two games at the 1958 World Cup.

question:
Question: When did the invasion start of the destination Task Force 38 was going to? Passage:Flint reported to the 3rd Fleet for duty at Ulithi on 27 December 1944, and six days later, sailed with Task Force 38 (TF 38) for a month-long cruise in support of the invasion of Luzon. She screened aircraft carriers as they launched strikes on Luzon, Taiwan, and the China coast, and fired protective anti-aircraft cover during a Japanese kamikaze attack on 21 January 1945. Replenishing at Ulithi from 26 January to 10 February, Flint then sailed with newly designated TF 38 for air strikes on Tokyo preceding the attack on Iwo Jima. Her force arrived off Iwo Jima on 21 February to provide anti-aircraft cover for the Marines who had landed two days previously, and Flint returned to Ulithi 12 March for a brief 2 days of replenishment.
