In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

Example Input: Question: What was the age difference between the 17th century Polish king and the person he helped regain Prussian in exchange for his support against Sweden? Passage:The Duchy of Prussia was a duchy in the eastern part of Prussia from 15251701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Konigsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (13851569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On July 29, 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia. Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.

Example Input: Question: In which city is the headquarter of the automaker that employed Bagot located? Passage:After the war he spent another eight years organising tourist services between Iraq, Persia (now Iran) and Syria for the Mesopotamian Trading Agency of Ashar, Basrah. His wife may have joined him in 1924. He returned to South Australia in 1926 with the intention of setting up a regular service between Adelaide and Darwin via Oodnadatta and Alice Springs. He conducted a demonstration run with eight men and four women in three Studebaker cars and a Thornycroft truck, leaving Adelaide on 18 May and arrived in Darwin on 3 June; left there on 7 June and returned to Adelaide on 25 June, travelling via Camooweal, Queensland and Marree, South Australia, publicised by Duncan and Fraser (agents for both Thornycroft and Studebaker) and as they were equipped with a short-wave transceiver, gave nightly reports on radio 5CL. Despite a second successful round trip that year, Bagot abandoned his idea of regular service when the Commonwealth Government turned down his application for a subsidy. He found employment with General Motors and in 1930 "Captain Bagot" as he was called by admirers (or "'Alphabetical Bagot' as he was known to the many who disliked him), founded the Citizens' League of South Australia, which opposed Unionism, Communism and the White Australia Policy as benefiting the working classes, yet also opposing Fascism. This was the time of the Great Depression and he also supported the Young People's Employment Council and the Rev. Samuel Forsyth's (18811960) Forsyth Industrial Colony "Kuitpo Colony" near Kuitpo Forest, which was training boys as farm workers. The Citizen's League attempted political influence by promising support to political candidates, and was a factor in the election of the Independent candidate George Connor to the Assembly seat of Alexandra in 1934.

Example Input: Question: What town is the team from that was ranked second when Ole Miss beat them in 2015? Passage:Ole Miss's 2015 season began with easy victories over FCS foe UT-Martin and the Mountain West's Fresno State, and continued their momentum by defeating then-no.2 Alabama on the road, which would become the signature victory of the Rebels' 2015 campaign. Ole Miss then rose to no.3 in the AP Poll, and although they were heavy favorites in their next matchup against Vanderbilt, they struggled mightily, but ultimately emerged victorious. They Rebels maintained their no.3 ranking before getting blown out by Florida on the road and fell to no.14 before bouncing back against New Mexico State. The Rebels entered their next game with a #13 ranking against rival Memphis, in what was one of the most anticipated in the history of Memphis football. Ole Miss, despite being double digit favorites, lost by 13 points, causing them to fall 11 spots in the rankings to no.24. The Rebels followed with two wins against SEC West opponents Texas A&M and Auburn and climbed to no.18 in the rankings and controlled their own destiny the SEC West, but a heartbreaking loss to Arkansas the following week caused them to fall to second place in the SEC West and to fall out of the rankings for the first time since the 2013 season. However, Ole Miss finished the regular season with double digit wins over ranked SEC Rivals LSU and Mississippi State and rose to no.12 in the College Football Playoff poll, which earned them a Sugar Bowl berth for the first time since 1970, where they defeated no.16 Oklahoma State and ultimately finished ranked no.10 in the AP Poll, their first top-ten finish since 1969.
