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: What was the capital of the Republic of Rawanda? Passage:In 1962, the Belgian mandate of Ruanda-Urundi received independence, creating the Republic of Rwanda and the Kingdom of Burundi. Both states had traditionally had monarchies dominated by the Tutsi ethnic group over a Hutu ethnic majority but Rwanda's monarchy was abolished by a political revolution in 1959-61. In the first years of independence, Burundi seemed to have achieved a balance between ethnic groups which brought members of the different ethnic groups into government, moderated in part by the mwami (king) Mwambutsa IV who was popular with all groups but was himself Tutsi. Both Tutsi, Hutu and Ganwa were part of the dominant political party, the Union for National Progress (Union pour le Progrès national, UPRONA). In October 1961, shortly before the date scheduled for independence, the Burundian Prime Minister Prince Louis Rwagasore was assassinated, raising ethnic tensions in the country. After a period of rule by Tutsi prime ministers, Mwambutsa appointed Burundi's first Hutu leader, Pierre Ngendandumwe, but Ngendandumwe was assassinated in January 1965 by a Rwandan Tutsi. Elections held in May 1965 took place in an atmosphere of strong ethnic tension. Hutu candidates gained a majority, but Mwambutsa deposed the Hutu Prime Minister Joseph Bamina and instead installed a Tutsi candidate, Léopold Biha, in October 1965.

Example Input: Question: How long did the Battle of Jumonville Glen last? Passage:The Ohio Country located between Britain's Thirteen Colonies and France's New France saw France and Britain clash. In 1753 the French sent an expedition south from Montreal that began constructing forts in the upper reaches of the Ohio River. In 1754 the Province of Virginia sent the Virginia Regiment led by George Washington to the area to assist in the construction of a British fort at present-day Pittsburgh, but the larger French force had driven away a smaller British advance party and built Fort Duquesne. Washington and some native allies ambushed a company of French scouts at the Battle of Jumonville Glen in late May 1754. In the skirmish the French envoy Joseph Coulon de Jumonville was left dead leading to a diplomatic incident. The French responded in force from Fort Duquesne, and in July Washington was forced to surrender at the Battle of Fort Necessity. Despite the conflict between them, the two nations were not yet formally at war.

Example Input: Question: Did spark gap transmitters have any uses after radio transmitters replaced them? Passage:The discovery of the triode's amplifying ability in 1912 revolutionized electrical technology, creating the new field of electronics, the technology of active (amplifying) electrical devices. The triode was immediately applied to many areas of communication. Triode "continuous wave" radio transmitters replaced the cumbersome inefficient "damped wave" spark gap transmitters, allowing the transmission of sound by amplitude modulation (AM). Amplifying triode radio receivers, which had the power to drive loudspeakers, replaced weak crystal radios, which had to be listened to with earphones, allowing families to listen together. This resulted in the evolution of radio from a commercial message service to the first mass communication medium, with the beginning of radio broadcasting around 1920. Triodes made transcontinental telephone service possible. Vacuum tube triode repeaters, invented at Bell Telephone after its purchase of the Audion rights, allowed telephone calls to travel beyond the unamplified limit of about 800 miles. The opening by Bell of the first transcontinental telephone line was celebrated 3 years later, on January 25, 1915. Other inventions made possible by the triode were television, public address systems, electric phonographs, and talking motion pictures.
