Question: Question: How old was Warren Harding the year Coolidge was born? Passage:Calvin Coolidge (born John Calvin Coolidge Jr.; ; July 4, 1872 – January 5, 1933) was an American politician and lawyer who served as the 30th president of the United States from 1923 to 1929. A Republican lawyer from New England, born in Vermont, Coolidge worked his way up the ladder of Massachusetts state politics, eventually becoming governor of Massachusetts. His response to the Boston Police Strike of 1919 thrust him into the national spotlight and gave him a reputation as a man of decisive action. The next year, he was elected vice president of the United States, and he succeeded to the presidency upon the sudden death of Warren G. Harding in 1923. Elected in his own right in 1924, he gained a reputation as a small government conservative and also as a man who said very little and had a rather dry sense of humor.
 Links: a. Vice President of the United States b. Politics c. Boston Police Strike d. Warren G. Harding

Question: Question: How many tracks were on the band's debut US album? 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.
