Final answer:
Families and communities are increasingly dependent on broader networks of exchange and specialized institutions. This shift is due to societal changes like industrialization, urbanization, and globalization, resulting in smaller family sizes and the necessity of interdependence in market-oriented economies.
Step-by-step explanation:
Families and communities are not able to function as self-sufficient units due to various sociocultural and economic changes. The statements that support this idea include the increased exchange of goods and services between villages, symbolizing a move away from self-sufficiency towards market-oriented economies. Additionally, the development of formal educational institutions shows a shift from family-based, informal education to more specialized and institutionalized forms of knowledge transfer, which is necessary for thriving in modern economies.
As societies have industrialized and become more urbanized, they have joined the global marketplace, and the function of traditional family units has been transformed. Industrialization reduced the necessity for large families in agricultural labor and created new job opportunities in urban areas, leading to decreased family sizes and increased reliance on external institutions for needs such as education, health care, and social services.
Moreover, the shift from rural traditional or command economies to urban market-oriented economies has affected every aspect of the social fabric. The globalization of economies and the interdependency of businesses and workers make self-sufficiency impractical at both family and community levels, necessitating a networked approach to living and working. Therefore, the interconnectedness of modern societies and economies underpins the shift away from self-reliant family and community units.
