A couple who live together before marrying are practicing which kind of socialization?

1. Socialization does not stop once childhood ends. 2. Adults rehearse roles they have not taken up yet. 3. Preparing for a future life role in this way is anticipatory socialization. 4. Parents-to-be reading infant care books and savers planning retirement are the same move. _Source: OpenStax Introduction to Sociology 2e (CC BY 4.0), Ch 3 "Culture", Ch 4 "Society and Social Interaction" and Ch 5 "Socialization", section 5.4 Socialization Across the Life Course_
