Final answer:
Option C best supports the claim that college is a significant event in a student's life as it marks the onset of independence and personal responsibility.
Step-by-step explanation:
Among the supporting details provided, option C best supports the claim that college is a significant event in a student's life. It suggests a rite of passage or a major shift in responsibility from the structured environment of high school to the self-directed world of college. This transition requires students to be independent, for the first time they must make choices about attending classes without the enforced attendance policies of high school. This new level of personal responsibility signifies a major change in a student's life and highlights the importance of the college experience. Moreover, this is confirmed by historical patterns of increasing college enrollment and the social expectation that in the U.S., attending college or joining the workforce happens soon after high school graduation, as opposed to taking a year 'off'. Therefore, a student's journey through college inherently carries a significant weight as it serves as a transformational period from adolescence to adulthood.
