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: Which group ruled the area for a longer period of time, the Arabs or the Byzantines? Passage:The first permanent Arab settlement on Sicily occurred in 827, but it was not until Taormina fell in 902 that the entire island fell under their sway, though Rometta held out until 965. In that year the Kalbids established the independence of their emirate from the Fatimid Caliphate. In 1061 the first Norman liberators took Messina, and by 1071 Palermo and its citadel (1072) were captured. In 1091 Noto fell to the Normans, and the conquest was complete. Malta fell later that year, though the Arab administration was kept in place, marking the final chapter of this period. The conquests of the Normans established Roman Catholicism firmly in the region, where Eastern Christianity had been prominent during the time of Byzantine rule and even remained significant during Islamic period. Widespread conversion ensued, leading to the disappearance of Islam in Sicily by the 1280s. In 1245, Muslim Sicilians were deported to the settlement of Lucera, by order of Holy Roman Emperor Frederick II. In 1300, Giovanni Pipino da Barletta, count of Altamura, seized Lucera and exiled or sold into slavery its population, bringing an end to the medieval Muslim presence in Italy.

[EX Q]: Question: What was the total attendance at Duke University the final year that Poteat was a professor there? Passage:William H. Poteat (19 April 1919 – 17 May 2000) was an American philosopher, scholar, and charismatic professor of philosophy, religion, and culture at the University of North Carolina at Chapel Hill from 1947 to 1957 and at Duke University from 1960 to 1987. During that time he did foundational work in the critique of Modern and Postmodern intellectual culture. He was instrumental in introducing scientist-philosopher Michael Polanyi and his Post-Critical philosophy to the United States. He was a master of the Socratic Method of teaching and identified himself a "practicing dialectician," skilled through the use of irony in "understanding and elucidating conflicting points of view" As a Post-Critical philosopher, he encouraged his students and the readers of his books to recover their authentic selves from the confusing, self-alienating abstractions of modern intellectual life. This task and purpose Poteat came to recognize as profoundly convergent with Michael Polanyi's critique of Modern Critical thought. His teaching and writing also drew upon and combined in new ways the ideas of seminal critics of modern culture such as Pascal, Kierkegaard, Arendt, Wittgenstein (later works), and Merleau-Ponty—whose thinking Poteat came to identify as "Post-Critical" (rather than Postmodern), using a key concept from Michael Polanyi's Personal Knowledge: Towards a Post-Critical Philosophy. His papers are archived at the Yale Divinity School Library.
