Input: Article: John's royal household was based around several groups of followers. One group was the familiares regis, John's immediate friends and knights who travelled around the country with him. They also played an important role in organising and leading military campaigns. Another section of royal followers were the curia regis; these curiales were the senior officials and agents of the king and were essential to his day-to-day rule. Being a member of these inner circles brought huge advantages, as it was easier to gain favours from the king, file lawsuits, marry a wealthy heiress or have one's debts remitted. By the time of Henry II, these posts were increasingly being filled by "new men" from outside the normal ranks of the barons. This intensified under John's rule, with many lesser nobles arriving from the continent to take up positions at court; many were mercenary leaders from Poitou. These men included soldiers who would become infamous in England for their uncivilised behaviour, including Falkes de Breaute, Geard d'Athies, Engelard de Cigonge and Philip Marc. Many barons perceived the king's household as what Ralph Turner has characterised as a "narrow clique enjoying royal favour at barons' expense" staffed by men of lesser status.

Now answer this question: John's royal household was based around what?

Output: several groups of followers

Input: Article: German philosophers have helped shape western philosophy from as early as the Middle Ages (Albertus Magnus). Later, Leibniz (17th century) and most importantly Kant played central roles in the history of philosophy. Kantianism inspired the work of Schopenhauer and Nietzsche as well as German idealism defended by Fichte and Hegel. Engels helped develop communist theory in the second half of the 19th century while Heidegger and Gadamer pursued the tradition of German philosophy in the 20th century. A number of German intellectuals were also influential in sociology, most notably Adorno, Habermas, Horkheimer, Luhmann, Simmel, Tonnies, and Weber. The University of Berlin founded in 1810 by linguist and philosopher Wilhelm von Humboldt served as an influential model for a number of modern western universities.

Now answer this question: When was the University of Berlin founded?

Output: 1810

Input: Article: Peer groups are essential to social and general development. Communication with peers increases significantly during adolescence and peer relationships become more intense than in other stages and more influential to the teen, affecting both the decisions and choices being made. High quality friendships may enhance children's development regardless of the characteristics of those friends. As children begin to bond with various people and create friendships, it later helps them when they are adolescent and sets up the framework for adolescence and peer groups. Peer groups are especially important during adolescence, a period of development characterized by a dramatic increase in time spent with peers and a decrease in adult supervision. Adolescents also associate with friends of the opposite sex much more than in childhood and tend to identify with larger groups of peers based on shared characteristics. It is also common for adolescents to use friends as coping devices in different situations. A three-factor structure of dealing with friends including avoidance, mastery, and nonchalance has shown that adolescents use friends as coping devices with social stresses.

Now answer this question: How is adolescence defined socially?

Output:
a period of development characterized by a dramatic increase in time spent with peers and a decrease in adult supervision
