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: How many members did No. 11 Group have during the years of the Blitz? Passage: the Second World War, the station was very active during the Battle of Britain and the Blitz in 194041 in No. 12 Group (controlled from RAF Watnall in Nottingham) as it was the main fighter station for a lot of the southern East Midlands, and fighters from the station would often patrol as far as Birmingham. During the Battle of Britain many squadrons were rotated through Wittering to spells in the south of England with No. 11 Group that was bearing the brunt of the battle. With many of the Luftwaffe raids during the Blitz taking part at night, Wittering-based squadrons were instrumental in the development of night combat techniques. These included the use of the Turbinlite aircraft which replaced the nose with a powerful searchlight insulated in the nose of Havocs and Bostons. In April 1943 No. 141 Squadron were moved in, operating de Havilland Mosquitoes. 1943 also saw the station host 2 USAAF squadrons, albeit temporarily: 63 Fighter Squadron USAAF with its P47s operated from Wittering between January and March before moving to RAF Horsham St Faith; 55 Fighter Squadron operated its P38s and P51s from Wittering between August and March 1944 before moving to nearby RAF Kingscliffe.

Example Input: Question: How many total teams participated in the cup the team won in 2017? Passage:From their foundation, the team primarily played five, seven and eleven-a-side exhibition matches, which were filmed and uploaded to their YouTube channel. By September 2016, the team's Instagram account had over 100,000 followers, their Twitter account 41,000, and a 'penalty challenge' video uploaded to YouTube had accumulated over one million views. Hashtag United played various teams including a Comedians XI whom they beat 191, Google, the GB Deaf Team, Barawa and a Manchester City staff team, with opponents fielding former professional footballers such as Paul Dickov, Graeme Le Saux and Ray Parlour, and celebrities including Omid Djalili. At one point in 2016, the club was close to signing professional footballer Adebayo Akinfenwa. In 2017 the club won the EE Wembley Cup, a competition that Spencer FC had won in 2015 and 2016; the team included Scott Pollock, who went on to sign professional terms with Northampton Town.

Example Input: Question: Does the college that Harrison graduated from in 1922 have more students than the one he graduated from in 1924? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.
