In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Input: Consider Input: Question: What modern day country did the Efe people populate? Passage:In modern times, the creation of relatively simple dome-like structures has been documented among various indigenous peoples around the world. The wigwam was made by Native Americans using arched branches or poles covered with grass or hides. The Efé people of central Africa construct similar structures, using leaves as shingles. Another example is the igloo, a shelter built from blocks of compact snow and used by the Inuit people, among others. The Himba people of Namibia construct "desert igloos" of wattle and daub for use as temporary shelters at seasonal cattle camps, and as permanent homes by the poor. Extraordinarily thin domes of sun-baked clay 20 feet in diameter, 30 feet high, and nearly parabolic in curve, are known from Cameroon.

Input: Consider Input: Question: How old was the writer who gave the band a cryptical review in the Village Voice? Passage:While in London performing at The Rainbow Theatre, Dingwall's, and trendy Cabaret Futura, the Bongos recorded their early singles and their well-received debut EP Time and the River for UK-based Fetish Records. Cover designs for their Fetish releases were created by influential graphic artist Neville Brody, who was soon to become the designer of The Face magazine. The group's love of avant-garde performers brought them in touch with artists such as Throbbing Gristle and Clock DVA who performed with them live in London, and on their recordings. Their debut U.S. album, Drums Along the Hudson, compiled from the band's British singles, was released in 1982 to widely favorable reviews on both sides of the Atlantic. While Trouser Press suggested that the group "may trade a certain amount of substance for easy appeal," it added that "there's no better musical equivalent of whipped cream anywhere." Writing in the Village Voice, Robert Christgau dryly commented that "for all their jumpy originality [the songs are] still slight, and Richard Barone's lyrics are so oblique you have to wonder what his angle is." In 2007 however, Jim DeRegotis wrote in the Chicago Sun-Times: "The initial impression of naiveté is offset by deceptively simple lyrics that actually hint at deep, dark mysteries and unfathomed mystical enigmas." The group's cover of T. Rex's "Mambo Sun" reached No. 22 on the Billboard Dance Chart. A thriving Hoboken pop scene emerged, triggered by the Bongos and Maxwell's, which gained national media attention, and drew many bands and fans to the city. An August 1, 1982 article in the New York Times Real Estate section hinted at the scene's popularity as an influence on increasing rents and property values.

Input: Consider Input: Question: How long was Patasse leader of the MLPC? Passage:On 3 March 1982, opposition politician and leader of the MLPC party, Ange-Félix Patassé, returned from exile to the Central African Republic and staged an unsuccessful coup against General André Kolingba (who himself took power in the 1981 coup d'état) with the help of a few military officers, such as General François Bozizé, who accused Kolingba of treason and proclaimed the change of power on Radio Bangui. Four days later, having failed to gain the support of the Central African Armed Forces, Patassé went in disguise to the French Embassy in the Central African Republic to seek refuge. After heated negotiations between the Kolingba government and France, Patassé was allowed to leave for exile in Togo. Bozizé fled to the north of the country with 100 soldiers, before obtaining refuge in France.
