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: 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: Of the cities Budi and his family lived in while he was growing up, which one is oldest? Passage:Budi Darma, BA, MA, Prof. Emeritus (born April 25, 1937 in Rembang, Central Java, Indonesia) is often described as one of Indonesia's most influential writers. He is the fourth of six children, all male.

He then studied at the English Literature Department, Faculy of Letters, University of Gadjah Mada. After graduating in 1963, Budi moved to Iowa for the International Writing Program at the University of Iowa. In 1970, he received a scholarship from the East-West Center to study humanities at the University of Hawaii, before graduating with an MA from Indiana University Bloomington in 1976. Four years later, in 1980, he earned his Ph.D for his dissertation on "Character and Moral Judgment in Jane Austen's Novels", from the same university. His return to Indonesia was followed by a succession of notable appointments: between the years 1984-1987 he was appointed Dean of the English Department of the State University of Surabaya (formerly IKIP Surabaya), became a member of the Arts Council, and Rector of the Surabaya Teachers' Training College. Budi Darma continued lecturing at the English Department of the State University of Surabaya until his retirement, at the age of 70, in 2007.

Example Input: Question: What year did Masashi win national amateur title at Senshu University? Passage:Oso was interested in sumo from a young age, as his father was the director of the Ibaraki Prefecture sumo association. He won national amateur titles at high school and at Senshu University, where he was a rival of Tosanoumi. He made his professional debut in January 1993 in the third makushita division, as due to his amateur achievements he had been given makushita tsukedashi status. He breezed through makushita undefeated with two consecutive 7–0 scores to earn promotion to the second jūryō division, whereupon he changed his shikona from Oso to Musōyama, meaning "twin warrior mountain." He made his debut in the top makuuchi division in September 1993. It took him only seven tournaments from his professional debut to make the san'yaku ranks, debuting at sekiwake in March 1994. In September he won his first eleven matches, finishing as runner up to Takanohana with a fine 13–2 record. Over the next few years he was regularly ranked at either sekiwake or komusubi, but was unable to make the next step up. He suffered a number of injuries, including a dislocated shoulder and a persistent problem with his left big toe which affected his speed of movement.
