[Q]: Extract the answer to the question from the following context. Question: How was the land kept fertile while the warriors were fighting? Context: In the late 14th century, in the Grand Duchy of Lithuania, Vytautas the Great reformed the Grand Duchy's army: instead of calling all men to arms, he created forces comprising professional warriorsbajorai ("nobles"; see the cognate "boyar"). As there were not enough nobles, Vytautas trained suitable men, relieving them of labor on the land and of other duties; for their military service to the Grand Duke, they were granted land that was worked by hired men (veldams). The newly formed noble families generally took up, as their family names, the Lithuanian pagan given names of their ennobled ancestors; this was the case with the Gostautai, Radvilos, Astikai, Kesgailos and others. These families were granted their coats of arms under the Union of Horodlo (1413).

[Q]: Extract the answer to the question from the following context. Question: Which type of lighting saves the more energy, incandescent or fluorescent? Context: Objections to banning the use of incandescent light bulbs include the higher initial cost of alternatives and lower quality of light of fluorescent lamps. Some people have concerns about the health effects of fluorescent lamps. However, even though they contain mercury, the environmental performance of CFLs is much better than that of light bulbs, mostly because they consume much less energy and therefore strongly reduce the environmental impact of power production. LED lamps are even more efficient, and are free of mercury. They are regarded as the best solution in terms of cost effectiveness and robustness.

[A]: fluorescent

[Q]: Extract the answer to the question from the following context. Question: What country held sway in Germany? Context: Austria was not able to retake Silesia or make any significant territorial gain. However, it did prevent Prussia from invading parts of Saxony. More significantly, its military performance proved far better than during the War of the Austrian Succession and seemed to vindicate Maria Theresa's administrative and military reforms. Hence, Austria's prestige was restored in great part and the empire secured its position as a major player in the European system. Also, by promising to vote for Joseph II in the Imperial elections, Frederick II accepted the Habsburg preeminence in the Holy Roman Empire. The survival of Prussia as a first-rate power and the enhanced prestige of its king and its army, however, was potentially damaging in the long run to Austria's influence in Germany.

Similarly, in regard to passages from the Enneads, "The only space or place of the world is the soul" and "Time must not be assumed to exist outside the soul", Ludwig Noire wrote: "For the first time in Western philosophy we find idealism proper in Plotinus, However, Plotinus does not address whether we know external objects, unlike Schopenhauer and other modern philosophers.
