TASK DEFINITION: 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.
PROBLEM: 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.

PROBLEM: Question: Out of the two fastest men in the 2018 Rallye Deutschland, which one started racing first? Passage:Five-time world champion Sébastien Ogier was the fastest man to finish the day other than the defending rally winner Ott Tänak, who set five out of six fastest stage times and built a 12.3-second lead over the Frenchman, while championship leader Thierry Neuville was another 15.1 seconds behind. Elfyn Evans climbed up three places in the afternoon loop and edged Jari-Matti Latvala by a second. Dani Sordo completed the day in sixth, only one-tenth of a second ahead of Esapekka Lappi, who failed to come to terms with dirt dragged onto the roads by the early starters. Craig Breen lost some time due to being caught in a heavy rain shower in the early stage in the eighth place, followed by Andreas Mikkelsen, who was struggling with his i20's handling and chose to change his driving style, in ninth, only one second behind. Teemu Suninen, driving a third Fiesta, in tenth. Lacking of power caused Mads Østberg to fail to find the pace like Finland, which made him cleared the day off the leaderboard in eleventh overall.

PROBLEM: Question: How long is the river that bordered the land occupied by Bavarians? Passage:In the meantime, the Germanic tribe of the Bavarii (Bavarians), vassals of the Franks, had developed in the 5th and 6th century in the west of the country and in what is now known as Bavaria, while what is today Vorarlberg had been settled by the Alemans. In the northern alps the Bavarians had become established as a stem dukedom around 550 AD, under the rule of the Agilolfings until 788 as an eastern outpost of the Frankish Empire. At that time the lands occupied by the Bavarians extended south to current South Tyrol, and east to the river Enns. The administrative center was at Regensburg. Those groups mixed with the Rhaeto-Romanic population and pushed it up into the mountains along the Puster Valley.
