Final answer:
Ruth counters Jorge by using an analogy, showing that personal experience is not a necessary condition to write about a historical time period effectively, as evidenced by writers who cover Roman culture without having lived in ancient times.
Step-by-step explanation:
Ruth responds to Jorge's criticism by offering an analogy to counter an unstated assumption of Jorge's argument. She effectively illustrates that one does not need to be contemporaneous with a historical period to write about it with authority and insight. Ruth uses the example of writers who successfully write about Roman culture despite not having lived in ancient times to challenge the idea that one must have been a part of the 1960s to write accurately about its rock music. This demonstrates that historical and cultural understanding transcends one's personal experience of the time period in question.
