Q: Extract the answer to the question from the following context. Question: How is lignite used for energy? Context: The traditional energy supply of Thuringia is lignite, mined in the bordering Leipzig region. Since 2000, the importance of environmentally unfriendly lignite combustion has declined in favour of renewable energies, which reached an amount of 40% (in 2013), and more clean gas combustion, often carried out as Cogeneration in the municipal power stations. The most important forms of renewable energies are Wind power and Biomass, followed by Solar energy and Hydroelectricity. Furthermore, Thuringia hosts two big pumped storage stations: the Goldisthal Pumped Storage Station and the Hohenwarte Dam.
A: combustion

Q: Extract the answer to the question from the following context. Question: What was the dominant script during the Han period? Context: Contrary to the popular belief of there being only one script per period, there were in fact multiple scripts in use during the Han period. Although mature clerical script, also called (bafen) script, was dominant at that time, an early type of cursive script was also in use by the Han by at least as early as 24 BC (during the very late Western Han period),[b] incorporating cursive forms popular at the time, well as many elements from the vulgar writing of the Warring State of Qin. By around the time of the Eastern Jin dynasty, this Han cursive became known as zhangcao (also known as / licao today), or in English sometimes clerical cursive, ancient cursive, or draft cursive. Some believe that the name, based on zhang meaning "orderly", arose because the script was a more orderly form of cursive than the modern form, which emerged during the Eastern Jin dynasty and is still in use today, called jincao or "modern cursive".
A: mature clerical script, also called (bafen) script

Q: Extract the answer to the question from the following context. Question: Who proposed that biological measure should be developed and used? Context: In the paper "Who's Gay? Does It Matter?", Ritch Savin-Williams proposes two different approaches to assessing sexual orientation until well positioned and psychometrically sound and tested definitions are developed that would allow research to reliably identify the prevalence, causes, and consequences of homosexuality. He first suggests that greater priority should be given to sexual arousal and attraction over behaviour and identity because it is less prone to self- and other-deception, social conditions and variable meanings. To measure attraction and arousal he proposed that biological measures should be developed and used. There are numerous biological/physiological measures that exist that can measure sexual orientation such as sexual arousal, brain scans, eye tracking, body odour preference, and anatomical variations such as digit-length ratio and right or left handedness. Secondly, Savin-Williams suggests that researchers should forsake the general notion of sexual orientation altogether and assess only those components that are relevant for the research question being investigated. For example:

Q: Extract the answer to the question from the following context. Question: Who was in charge of driving the trams? Context: Within the city there have been two tram networks in operation. A proposal to develop a horse-drawn tram (linking the city's railway termini) was made by American George Francis Train in the 1860s, and implemented in 1872 by the Cork Tramway Company. However, the company ceased trading in 1875 after Cork Corporation refused permission to extend the line, mainly because of objections from cab operators to the type of tracks which although they were laid to the Irish national railway gauge of 5 ft 3in protruded from the road surface.[citation needed]
A:
cab operators
