In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: Who was the leader of the Republic? Passage:Fort Ino was constructed in 1909-1916 on Cape Inoniemi on the Karelian Isthmus, within the borders of Viipuri Province of the autonomous Grand Duchy of Finland. It was intended to protect the capital city of Petrograd (Saint Petersburg) and the naval base at Kronstadt, and was served by a railroad and a harbor. As Finland had become independent, on March 1, 1918, during the Finnish Civil War, in a friendship treaty the Finnish Red Guards' Edvard Gylling and Oskari Tokoi in the name of the Finnish Socialist Workers' Republic ceded the fortress to Soviet Russia in exchange for the city of Petsamo. However, the Finnish White Guards, who ultimately came out victorious in the civil war, demanded the fortress back, without offering a similar return of Petsamo, and on April 24 the 5th Jaeger Regiment under Major Hugo Viktor Österman laid siege to it. On May 8 Germany demanded Soviet Russia return the fort to Finland, and the Soviet government for fear of violating the Treaty of Brest-Litovsk withdrew its support to the crew. On May 14, 1918, the Soviet crew destroyed the batteries and evacuated to Kronstadt aboard the battleship Respublika. With the Treaty of Tartu in 1920, Finland undertook to disarm it completely within a year.

Example Input: Question: Besides Umbriel, what are the names of the moons that orbit Uranus? Passage:Umbriel orbits Uranus at the distance of about , being the third farthest from the planet among its five major moons. Umbriel's orbit has a small eccentricity and is inclined very little relative to the equator of Uranus. Its orbital period is around 4.1 Earth days, coincident with its rotational period. In other words, Umbriel is a synchronous or tidally locked satellite, with one face always pointing toward its parent planet. Umbriel's orbit lies completely inside the Uranian magnetosphere. This is important, because the trailing hemispheres of airless satellites orbiting inside a magnetosphere (like Umbriel) are struck by magnetospheric plasma, which co-rotates with the planet. This bombardment may lead to the darkening of the trailing hemispheres, which is actually observed for all Uranian moons except Oberon (see below). Umbriel also serves as a sink of the magnetospheric charged particles, which creates a pronounced dip in energetic particle count near the moon's orbit as observed by Voyager 2 in 1986.

Example Input: Question: What injury did Chic Brodie sustain? Passage:On 21 November, Vale picked up their third league win of the campaign, beating lowly Barnsley 2–0 at Oakwell. Youth players continued to be drafted in as Vale finished the year with four straight league defeats, picking up injuries and sendings off along the way. In December, Hancock was sold to Ipswich Town for £10,000. A 2–1 victory over promotion-chasers Brentford on 2 January failed to spark a revival, partly due to the fact that the Bees were forced to play almost the entire match with ten players and an outside player in goal following an injury to Chic Brodie. Steele tried to play a settled team, but that proved to be as unsuccessful as when he switched the team round constantly. By the end of the month the club were bottom of the league and morale was low. In mid-February, the club four points short of safety, Steele left the club 'by mutual consent', as Jackie Mudie was appointed caretaker manager. Following a 4–0 hammering from Gillingham, Mudie signed veteran stopper Jimmy O'Neill from Darlington, and the former Ireland international seemed to improve the team, as just two defeats in eight games followed. Mudie instilled discipline into the team, and so was made manager on a permanent basis on 3 March. He then ensured Reg Davies was transferred to Leyton Orient. He tried and failed to re-sign Terry Harkin from Crewe Alexandra. One win in their final six games doomed the Vale to relegation, just as survival seemed possible. Only 3,521 witnessed a final day victory over Walsall.
