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: 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: Question: What is the oldest city that was chosen for filming Aeon Flux? Passage:The screenplay was written by Phil Hay and Matt Manfredi, and directed by Karyn Kusama. It was based on the animated TV series by Peter Chung, who had a minor role in this film version of his work. In the early stages of production, actress Michelle Rodriguez was considered for the part of on. She had previously worked with Kusama in Girlfight. Kusama had originally suggested filming in Brasilia, the capital of Brazil, because the 20th-century modern architecture of that city fit with her vision of Bregna. The producers rejected the idea because Brasilia lacked the infrastructure and technical expertise to support a major film production. After several cities were scouted, Berlin and Potsdam in Germany were chosen for filming. Berlin had several locations that fit into the organic yet structured world of on Flux. The crew gained permission to film in several locations that had never allowed such access before, including the Treptow Crematorium, the Adlershof Trudelturm and Windkanal wind tunnel facility, and the Haus der Kulturen der Welt ("House of the World's Cultures"). Additional locations included the Bauhaus Archive and a dissection theatre built in 1790 to train veterinarians, part of the Berlin animal shelter. It was used as the Handler space. Filming was temporarily suspended for a month during September 2004 while Theron recovered from a neck injury she sustained during stunt-work on the tenth day of shooting. She was hospitalized in Berlin for five days and required about six weeks of physiotherapy to recover.

Question: Question: What is the maximum width of the channel that the tropical storm moved northward toward? Passage:On June 19, a tropical disturbance was detected between Swan Island and the Honduran coast. However, surface data in the vicinity did not indicate a closed circulation until 12 UTC on June 20. At 14 UTC that day, an Air Force reconnaissance plane located near 24N 84W reported gale-force winds of (). At the time, this was taken to indicate that a tropical storm had formed about northwest of Swan Island. Reanalysis by the Hurricane Research Division in 2013, however, determined that a tropical storm formed farther northwest, near 19N 86W. Squally weather, and winds of moderate tropical storm force, was reported in connection with the tropical storm as it moved generally northward, toward the Yucatan Channel. Little strengthening occurred over the next two days, until after 12 UTC on June 22. At that time, a period of rapid deepening commenced: within 24 hours, the cyclone increased its winds from to . At the same time, its track made a sharp bend toward the northeast, threatening the Florida peninsula. While no central pressure was recorded, Hurricane Hunter aircraft flew into the storm on June 23 and reported winds of at 2015 UTC. As with most early reconnaissance data, such readings are suspect; however, based upon the reconnaissance measurement, the storm was originally listed in the Atlantic hurricane database as a Category 3 hurricane. Later, reanalysis lowered this estimate to , equal to Category 2 on the modern Saffir-Simpson Hurricane Scale, due primarily to the absence of corroboration. After peaking late on June 23, the storm quickly lost intensity.
