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: When was the person who designed the new campus born? Passage:Consequently, in 1870, it moved to a (then greenfield) site on Gilmorehill in the West End of the city, around three miles (5 km) west of its previous location, enclosed by a large meander of the River Kelvin. The original site on the High Street was sold to the City of Glasgow Union Railway and replaced by the College goods yard. The new-build campus was designed by Sir George Gilbert Scott in the Gothic revival style. The largest of these buildings echoed, on a far grander scale, the original High Street campus's twin-quadrangle layout, and may have been inspired by Ypres' late medieval cloth hall; Gilmorehill in turn inspired the design of the Clocktower complex of buildings for the new University of Otago in New Zealand. In 1879, Gilbert Scott's son, Oldrid, completed this original vision by building an open undercroft forming two quadrangles, above which is his grand Bute Hall (used for examinations and graduation ceremonies), named after its donor, John Crichton-Stuart, 3rd Marquess of Bute. Oldrid also later added a spire to the building's signature gothic bell tower in 1887, bringing it to a total height of some . The local Bishopbriggs blond sandstone cladding and Gothic design of the building's exterior belie the modernity of its Victorian construction; Scott's building is structured upon what was then a cutting-edge riveted iron frame construction, supporting a lightweight wooden-beam roof. The building also forms the second-largest example of Gothic revival architecture in Britain, after the Palace of Westminster. An illustration of the Main Building currently features on the reverse side of the current series of £100 notes issued by the Clydesdale Bank.

Example Input: Question: Of the two bays the USS Lardner operated in, which had the largest land area? Passage:After patrol duty early in October, Lardner returned to escort duty between New Caledonia and the Solomons, then screened task forces operating out of Purvis Bay in the Bougainville Campaign. She bombarded Bougainville on 29 November, and continued occasional bombardments along with escort missions through January 1944. On 14 February, Lardner sailed north with TF 38 to cover initial landings on Green Island, and on the way was attacked by six Aichi D3A "Val" dive bombers. Late in February, the destroyer bombarded Rabaul; searched the Bismarck Sea for enemy shipping; and then attacked Karavia Bay, sinking an enemy cargo ship of the Heito Maru class 25 February. Later that day she bombarded Kavieng, receiving a few shrapnel holes from extremely heavy and accurate enemy return fire. During March and April, Lardner operated with support forces for the Palaus raid, and with escort carriers during the landing at Hollandia, New Guinea.

Example Input: Question: Did the pop group that Foster was a keyboardist for have more than three members? Passage:Foster was a keyboardist for the pop group Skylark, discovered by Eirik Wangberg. The band's song "Wildflower" was a top ten hit in 1973. When the band disbanded, Foster remained in Los Angeles and together with Jay Graydon he formed the band Airplay, whose album of the same name is often labeled as important within the west coast AOR genre. In 1975, he played on George Harrison's album Extra Texture. He followed that up by playing the Fender Rhodes and clavinet on Harrison's album Thirty Three & 1/3 a year later. In 1976 Foster joined Guthrie Thomas on Thomas' second Capitol Records album, Lies and Alibis, with Ringo Starr and a host of many other famed performers. Foster was a major contributor to the 1979 Earth, Wind and Fire album I Am, as a studio player and arranger, as well as being a co-writer on six of the album's tracks. The most noteworthy being the song "After the Love Has Gone", for which Foster and his co-writers, Graydon and Bill Champlin, won the 1980 Grammy Award for Best R&B Song.
