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.

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.

Question: Of the first two post-doc positions John Ellis held, which company did he work for the longest? Passage:After completing his secondary education at Highgate School, he attended King's College, Cambridge, earning his PhD in theoretical (high-energy) particle physics in 1971. After brief post-doc positions at SLAC and Caltech, he went to CERN and has held an indefinite contract there since 1978. He was awarded the Maxwell Medal and the Paul Dirac Prize by the Institute of Physics in 1982 and 2005 respectively, and is an Elected Fellow of the Royal Society of London since 1985 and of the Institute of Physics since 1991. He was awarded an Honorary Doctorate from the University of Southampton, and twice won the First Award in the Gravity Research Foundation essay competition (in 1999 and 2005). He is also Honorary Doctor at Uppsala University.

Question: Who won the league the year that the Trotters finished in 17th place? Passage:Walter Rowley's "Trotters" finished in 17th place in 1947–48, 14th place in 1948–49, and 16th place in 1949–50. He scored six goals in 93 league games during his spell at Burnden Park. McShane joined Manchester United in exchange for defender John Ball and £5,000 in September 1950. He was signed to replace the departing Charlie Mitten. He scored seven goals in 31 appearances in the 1950–51 season, as the "Red Devils" finished second in the league. His first goal at Old Trafford came on 7 October 1950, in a 3–1 win over Sheffield Wednesday. He was part of the United side that won the First Division title in 1951–52, scoring one goal in 12 league games that season. His goal was an important one, as it came against rivals Manchester City in a 2–1 win at Maine Road on 15 September. He then struggled with a cartilage injury, and appeared just five times in the 1952–53 campaign, as Matt Busby's side dropped to eighth place.
