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.

Input: Consider 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.

Input: Consider Input: Question: How long did the person serving as Malyan Prime Minister during 1958 serve in office? Passage:Relations with the former state of South Vietnam were established when South Vietnam recognised the Federation of Malaya's independence on 1957. From that point, Malaya provided aid to the South Vietnamese regime in its fight against the Viet Cong and North Vietnamese army. Malayan Prime Minister Tunku Abdul Rahman made a first visit on 1958 which was reciprocated twice by the South Vietnamese President Ngô Đình Diệm on 28–31 January 1958 and in October 1961. By 1963, when Malaya transformed into Malaysia (with an additional territory in the island of Borneo), the main government in Kuala Lumpur worried the influence of North Vietnamese communists would threaten its existence in accordance to the Domino theory, thus changing its position to become very supportive of the American involvement in the Vietnam War as Malaysia had also experienced a communist insurgency of its own. Tunku Abdul Rahman then expressed these concerns in December 1966 and called on the United States and the United Kingdom to provide increased logistical support to war efforts in Vietnam. Malaysia hosted training courses in public administration and jungle warfare for government officials, and provided motorcycles to bolster the South Vietnamese police and military logistical capabilities. Towards the end of the Vietnam War in 1975, Malaysia closed its embassy in Saigon in two stages; first it withdrew the embassy dependants on 12 April 1975, before a complete closure 16 days later—two days before the fall of Saigon. Malaysia had also extended recognition to the short-lived Provisional Revolutionary Government of the Republic of South Vietnam within days of its formation in May 1975, citing Malaysia's impartial position on political ideology and social system.

Input: Consider Input: Question: What is the name of the person that married the artist who performed at the 1970 Palermo Pop Festival? Passage:Helped by his association with The Guardian, Cannon was able to contribute more substantial articles to the Los Angeles Times and the Chicago Sun-Times, and to underground magazines such as Creem. He wrote the 1970 documentary film London Rock, focusing on the UK's counterculture movement. He recalls that, together with Rolling Stone journalists David Dalton and Jonathan Cott, he joined Granada Television documentary-makers such as Jo Durden-Smith, John Sheppard and Michael Darlow in devising "prime-time networked shows designed as anthems of the revolution". Among these late-1960s projects, he says that the Johnny Cash at San Quentin TV special was his idea, and he "share[s] credit" for the ideas behind the concert films The Doors Are Open and The Stones in the Park. He also directed the film of Frank Zappa's performance at the 1970 Palermo Pop Festival, for RAI, Italy's national public broadcaster.
