Final answer:
It is true that there is a sociocultural trend of increased educational attainment by women in the United States, with a significant rise in the number of women obtaining college degrees compared to the past.
Step-by-step explanation:
A major sociocultural trend in the United States has been the increased educational attainment by women. This trend is true and reflects significant changes in societal norms and opportunities for women. Since the late 1970s, enrolment and graduation rates for men in college have been surpassed by those of women, resulting in more women attaining higher education levels. Historically, education for women was limited, reflecting in just 5.2% of women having college degrees in the 1950s. Now, that figure is approximately 38%, indicating a dramatic increase in educational achievements among women.
