Step-by-step explanation:
The statement that does NOT belong in terms of the changing dynamics of family life over the past 200 years is d. Family is the single dominant supporting institution for adolescents.
The changing dynamics of family life over the past 200 years have been influenced by various factors. Human life expectancy has increased significantly from 45 to 70 years of age, as improvements in healthcare and living conditions have reduced infant mortality rates and allowed people to live longer.
The second statement, b. People are having fewer and fewer children, is also accurate. In developed countries, birth rates have declined due to factors such as economic changes, urbanization, and increased access to birth control.
The third statement, c. After 1830, the proportion of family farms steadily declined, is also supported by historical evidence. The Industrial Revolution and economic shifts led to a decrease in the number of family-run farms as more people moved to urban areas for employment.
