Extract the answer to the question from the following context. Question: What was invented before the hydrogen gas blowpipe? Context: Hydrogen was liquefied for the first time by James Dewar in 1898 by using regenerative cooling and his invention, the vacuum flask. He produced solid hydrogen the next year. Deuterium was discovered in December 1931 by Harold Urey, and tritium was prepared in 1934 by Ernest Rutherford, Mark Oliphant, and Paul Harteck. Heavy water, which consists of deuterium in the place of regular hydrogen, was discovered by Urey's group in 1932. Francois Isaac de Rivaz built the first de Rivaz engine, an internal combustion engine powered by a mixture of hydrogen and oxygen in 1806. Edward Daniel Clarke invented the hydrogen gas blowpipe in 1819. The Dobereiner's lamp and limelight were invented in 1823.

Extract the answer to the question from the following context. Question: Which happened later, the Lexicon Technicum was published, or it was drafted? Context: The first technical dictionary was drafted by John Harris and entitled Lexicon Technicum: Or, An Universal English Dictionary of Arts and Sciences. Harris' book avoided theological and biographical entries; instead it concentrated on science and technology. Published in 1704, the Lexicon technicum was the first book to be written in English that took a methodical approach to describing mathematics and commercial arithmetic along with the physical sciences and navigation. Other technical dictionaries followed Harris' model, including Ephraim Chambers' Cyclopaedia (1728), which included five editions, and was a substantially larger work than Harris'. The folio edition of the work even included foldout engravings. The Cyclopaedia emphasized Newtonian theories, Lockean philosophy, and contained thorough examinations of technologies, such as engraving, brewing, and dyeing.

Extract the answer to the question from the following context. Question: What group starts with an L and ends in an s? Context: Menzies ran strongly against Labor's plans to nationalise the Australian banking system and, following victory in the 1949 election, secured a double dissolution election for April 1951, after the Labor-controlled Senate refused to pass his banking legislation. The Liberal-Country Coalition was returned with control of the Senate. The Government was returned again in the 1954 election; the formation of the anti-Communist Democratic Labor Party (DLP) and the consequent split in the Australian Labor Party early in 1955 helped the Liberals to another victory in December 1955. John McEwen replaced Arthur Fadden as leader of the Country Party in March 1958 and the Menzies-McEwen Coalition was returned again at elections in November 1958 their third victory against Labor's H. V. Evatt. The Coalition was narrowly returned against Labor's Arthur Calwell in the December 1961 election, in the midst of a credit squeeze. Menzies stood for office for the last time in the November 1963 election, again defeating Calwell, with the Coalition winning back its losses in the House of Representatives. Menzies went on to resign from parliament on 26 January 1966.
