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: What city did Stevens complete a Ph.D. in? Passage:In 1980, Stevens joined the Army under their split option training program and conducted basic training at Fort Dix, New Jersey and advanced individual training at Fort Sam Houston, Texas. While engaged in his military service, Stevens entered the University of Southern Maine in the Computer Science program in 1981. However, an enthusiastic professor (John Ricci) converted him to the study of Chemistry. He spent two summers working as an intern at the Brookhaven National Laboratory in Long Island with Professor Ricci, and Drs. Thomas Koetzle and Dick McMullan, where he first learned how to determine the molecular structure of compounds by X-ray and neutron diffraction. While there he also met a University of Southern California research team led by Dr. Robert Bau; after he obtained a Bachelor of Science degree in Chemistry at USM, he entered the University of Southern California in pursuit of a Doctor of Philosophy degree in Chemistry working with Professor Robert Bau and Nobel Laureate Professor, George Olah. He completed his Ph.D. in 26 months, graduating in 1988.

Question: How long had the NBA been in operation when the Chicago Bulls celebrated their 30th season in the league? Passage:The 1995–96 NBA season was the Bulls' 30th season in the National Basketball Association. During the offseason, the Bulls acquired rebound-specialist Dennis Rodman from the San Antonio Spurs, and signed free agent Randy Brown. Midway through the season, the team signed John Salley, who was released by the expansion Toronto Raptors. Salley won championships with the Detroit Pistons along with Rodman in 1989 and 1990. The 1996 Bulls is regarded to be the greatest Jordan team of the 90s and undoubtably of all time. This saw the Bulls set the record for most wins in an NBA regular season in which they won the championship, finishing with 72 wins and 10 losses. The regular season record was broken by the 2015–16 Golden State Warriors, who finished 73–9. The Warriors(2015-2016) have a connection to the (1995-1996) Bulls team, as Steve Kerr, the current Golden State coach, was a reserve point guard with the Bulls.
