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.

[EX 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.

[EX Q]: Question: Is the Philippine Sea part of the Pacific Ocean? Passage:Nueva Camarines is the name of a proposed new province of the Philippines to be created out of Camarines Sur in the Bicol Region of the island of Luzon. The proposed province would border Camarines Sur to the west, the Philippine Sea to the north, Albay to the south, and to the east the island province of Catanduanes across Maqueda Channel. Its capital is expected to be Tigaon if the bill is passed. House Bill 4820 which would create the province passed the House of Representatives of the Philippines with 229 votes in favor to one against in 2011 and is now under consideration by the Senate of the Philippines. However, at the end of 15th Congress, it failed to pass to the Senate. In the 16th Congress under then Representative Felix William Fuentebella, a bill is yet to be filed to repropose the creation of the province, due to lack of support from fellow Camarines Sur Representatives Maria Leonor Robredo and Salvio Fortuno. In the 18th congress under new Representative Arnulf Bryan Fuentebella.

Passage:Haskell was born in Palmyra, Maine in 1843 to Aretas Haskell and Sophia Hathorn (Haskell). He attended Bates College's Nichols Latin School/Maine Central Institute. Haskell was a great-nephew of Seth Hathorn who donated Bates' first building.

In the election he defeated Ella Knowles Haskell, whom he later married and then divorced in 1897. Henri Haskell died in 1921.
