The agreement among the members of a society to cooperate for social benefits and to form the society in which they live or it essentially binds people into a community that exists for mutual preservation is called Social Contract. People gain the civil freedom of being able to think and act rationally and morally but they sacrifice the physical freedom of being able to do whatever they please, when they enter into civil society. It is the vision that persons' political and moral obligations are dependent upon a contract. Jean-Jacques Rousseau believes that only by engaging into this contract that people become wholly human.

Assuming the question is about an excerpt from the article "Family and Households among Scandinavian Peasants" by Orvar Löfgren in <em>Ethnologica Scandinavia</em> (1974), the following statement supports the author's position: "marriage was necessary to support the economic underpinning of a typical family" (a).
Löfgren argues that marriage among peasants (and the ensuing children) enabled the families to be productive thanks to a division of the farming/housekeeping labor, as well as the ability to put resources in common. The phrase from the text which explicitly states this thesis is: "this made marriage a necessary condition for a viable farm unit."
