TASK DEFINITION: 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.
PROBLEM: Question: What year was Brian named the High King? Passage:The Ui Briuin Seola was one of the major branches of the powerful Ui Briuin dynasty, which had become the dominant force in Connacht by the 8th century. The genealogies list two sons of Murchadh mac Maenach: Urchadh and Urumhain. Urchadh mac Murchadh, King of Maigh Seola (also listed as king of Iarthair Connacht, died 945, in the 14th century Book of Ballymote) was father of Be Binn inion Urchadh, Princess of the Ui Briuin Seola and Queen of Thomond (fl. early 10th century). Be Binn married Cennetig mac Lorcain of Thomond to produce a son who would become the High King of Ireland (Irish: Ard-Ri na hEireann): Brian Boruma mac Cennetig, known in English as Brian Boru (c. 94123 April 1014). Brian broke the near monopoly of the Ui Neill over the High Kingship of Ireland and fought to unite Ireland as a people under one, native king. His father, Cennetig mac Lorcain of Thomond, was one of the principal leaders of the resistance to the Danish Viking incursions. Cennetig had several wives and children but positively assigned Be Binn as the mother of Brian Boruma.

PROBLEM: 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.

PROBLEM: Question: What is the square footage of the lake over which three simultaneous waterspouts were observed during the tornado outbreak that began on February 23rd? Passage:The second largest February tornado outbreak on record impacted the Gulf Coast and East Coast regions of the United States beginning on February 23. The first significant tornadoes of the outbreak moved across southeastern Louisiana and southern Mississippi that evening, leaving significant damage and three deaths. The towns of Livingston and Laplace, Louisiana sustained heavy damage from strong EF2 tornadoes, and another EF2 near Purvis, Mississippi killed one person in a mobile home. An EF3 tornado also caused major structural damage in Paincourtville, Louisiana before destroying an RV park in Convent, killing two people at that location. Three simultaneous waterspouts were observed over Lake Pontchartrain during the event as well. Later that night, a large supercell thunderstorm developed over the Gulf of Mexico and moved ashore, producing a destructive EF3 tornado in Pensacola, Florida. The tornado injured three people and destroyed homes, townhouses, apartments, and a GE warehouse.
