instruction:
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:
Question: How old was William Havemeyer's son when he retired from the sugar refining business? Passage:William Havemeyer (1770-1851) left Germany at age 15 and arrived in New York City after learning the trade of sugar refining in London. In New York he managed a sugar house on Pine Street before opening his own refinery on Vandam Street with his brother, Frederick Christian Havemeyer, who had come to New York in 1802. Together the two brothers operated the W. & F.C. Havemeyer Company sugar refineries, before passing the business on to their sons. His son William Frederick Havemeyer, retired from the sugar refining business in 1842 and entered politics, eventually serving three terms as Mayor of New York. In 1855 the family relocated their refineries to Brooklyn, where they remained as the business grew to acquire a commanding share of the United States sugar refining market under the leadership of Frederick's grandson, Henry Osborne Havemeyer. The Havemeyer refineries were incorporated as the American Sugar Refining Company in 1891 and became known as Domino Sugar in 1900. In the 20th century several of the family's members made notable contributions to the arts. Henry Osborne Havemeyer and his wife Louisine Havemeyer made large bequests to the Metropolitan Museum of Art and their daughter Electra Havemeyer Webb founded the Shelburne Museum.

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 Ngo inh Diem on 2831 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 latertwo 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.

question:
Question: What country was Bell located in? Passage:The piezoelectric properties of quartz were discovered by Jacques and Pierre Curie in 1880. The first quartz crystal oscillator was built by Walter G. Cady in 1921. In 1923, D. W. Dye at the National Physical Laboratory in the UK and Warren Marrison at Bell Telephone Laboratories produced sequences of precision time signals with quartz oscillators. In 1927, the first quartz clock was built by Warren Marrison and J.W. Horton at Bell Telephone Laboratories. The next 3 decades saw the development of quartz clocks as precision time standards in laboratory settings; the bulky delicate counting electronics, built with vacuum tubes, limited their use elsewhere. In 1932 a quartz clock was able to measure tiny variations in the rotation rate of the Earth over periods as short as a few weeks. In Japan in 1932, Issac Koga developed a crystal cut that gave an oscillation frequency with greatly reduced temperature dependence. The National Bureau of Standards (now NIST) based the time standard of the US on quartz clocks between the 1930s and the 1960s, after which it transitioned to atomic clocks. The wider use of quartz clock technology had to await the development of cheap semiconductor digital logic in the 1960s. The revised 14th edition of Encyclopdia Britannica stated that quartz clocks would probably never be affordable enough to be used domestically.
