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.

Example Input: Question: When was Clements High School established? Passage:KJ Noons is hapa kanaka, hapa haole—mixed ethnicity of native Hawaiian (from his mother's side) and European-American (from his father's side). Born and raised in Kailua-Kona, Hawaii, Noons comes from a family history of fighting. His father Karl was a professional kickboxer and was a top contender during the time he fought. Karl's passion for fighting and competing in combat sports influenced him to introduce his son to martial arts at a young age. At the age of five, Noons started training in Kenpō Karate. Often getting disqualified for fighting too hard in karate tournaments, Noons eventually started training in boxing and Muay Thai at the age of eight out of interest for full contact fighting. Noons competed as an amateur fighter and became the first student in the state of Hawaii to earn a junior black belt under Ed Parker at the age of 11. During his high school years, Noons moved to Houston, Texas due to the location of his father's job. While continuing to compete as a fighter, he also started playing football at Clements High School. At age 17, Noons won the ISKA Super Middleweight International Championship as an amateur in Sanshou. After winning the title and graduating from Clements High School, K.J. decided to pursue a career in combat sports, rather than go to college and continue with football.

Example Input: Question: How old was the king when he awarded Mairi and Knocker the Order of Léopold II, Knights Cross? Passage:Chisholm and Knocker soon came to the conclusion that they could save more lives by treating the wounded directly on the front lines. In November, they decided to leave the corps and set up their own dressing station five miles east in a town named Pervyse, north of Ypres, just one hundred yards from the trenches. Here, in a vacant cellar which they named "Poste de Secours Anglais" ("British First Aid Post"), the two would spend the next three and a half years tending to the wounded. No longer affiliated with the Belgian Red Cross, they began acting completely as free agents and had to support their work by raising their own funds. Through sheer perseverance Knocker was able to arrange for the two of them to be officially seconded to the Belgian garrison stationed there. In January 1915, they were both decorated by King Albert I of Belgium with the Order of Léopold II, Knights Cross (with palm) for their courageous work on the front lines. They were also awarded the British Military Medal and both made Officers of the Most Venerable Order of St. John of Jerusalem. Chisholm was also decorated with the Queen Elisabeth Medal of Belgium and the British campaign medals, including the 1914 Star. The two became instant celebrities earning the distinction of being among the most photographed women of the war.
