Extract the answer to the question from the following context. Question: What are dielectrics used in? Context: Most types of capacitor include a dielectric spacer, which increases their capacitance. These dielectrics are most often insulators. However, low capacitance devices are available with a vacuum between their plates, which allows extremely high voltage operation and low losses. Variable capacitors with their plates open to the atmosphere were commonly used in radio tuning circuits. Later designs use polymer foil dielectric between the moving and stationary plates, with no significant air space between them.
Ans: capacitor

Extract the answer to the question from the following context. Question: Which of the following is not a potential source of tensions for children: school, agriculture or home? Context: While full-time work hinders schooling, empirical evidence is varied on the relationship between part-time work and school. Sometimes even part-time work may hinder school attendance or performance. On the other hand, many poor children work for resources to attend school. Children who are not doing well at school sometimes seek more satisfactory experience in work. Good relations with a supervisor at work can provide relief from tensions that children feel at school and home. In the modern world, school education has become so central to society that schoolwork has become the dominant work for most children, often replacing participation in productive work. If school curricula or quality do not provide children with appropriate skills for available jobs or if children do nor have the aptitude for schoolwork, school may impede the learning of skills, such as agriculture, which will become necessary for future livelihood.
Ans: agriculture

Extract the answer to the question from the following context. Question: Who spoke Indo-Iranian Context: All Iranian languages are descended from a common ancestor, Proto-Iranian. In turn, and together with Proto-Indo-Aryan and the Nuristani languages, Proto-Iranian descends from a common ancestor Proto-Indo-Iranian. The Indo-Iranian languages are thought to have originated in Central Asia. The Andronovo culture is the suggested candidate for the common Indo-Iranian culture ca. 2000 BC.
Ans: Andronovo

Extract the answer to the question from the following context. Question: The first people honored in New Zealand received their accolades from __ Context: Appointments to the Order of the British Empire were discontinued in those Commonwealth realms that established a national system of honours and awards such as the Order of Australia, the Order of Canada, and the New Zealand Order of Merit. In many of these systems, the different levels of award and honour reflect the Imperial system they replaced. Canada, Australia, and New Zealand all have (in increasing level of precedence) Members of, Officers of, and Companions to (rather than Commanders of) their respective orders, with both Australia and New Zealand having Knights and Dames as their highest classes.
Ans: the British Empire
