Final answer:
The rising education rates and incomes for women have made marriage no longer an economic necessity. Men's job prospects are not the main reason for the declining attractiveness of marriage. Women are, in fact, pursuing higher education at increasing rates.
Step-by-step explanation:
The rising education rates and incomes for women have led to changes in the institution of marriage. One significant change is that marriage is no longer seen as an economic necessity for women. In the past, women may have relied on marriage as a way to secure financial stability. However, as women gain more education and higher-paying jobs, they have more economic independence and may choose not to get married or to delay marriage.
This does not mean that women will not be married at all in their lifetimes (option A). It simply means that marriage is no longer driven solely by economic factors. In fact, with the changing dynamics, some men who may have traditionally been considered high earners are marrying women who are also high earners (option B). This suggests that men's job prospects could be a factor in the attractiveness of marriage, but it is not the main reason for the changing trends.
The correct answer is therefore option C: marriage is no longer an economic necessity. Option D, which suggests that women are less likely to pursue higher education, is incorrect. The provided information states that women's education rates are rising, indicating that more women are pursuing higher education.
