Final answer:
Without access to the specific audio referenced, it is not possible to determine who Bárbara will visit next year. The question seems to be part of an audio comprehension exercise typically found in a language learning curriculum.
Step-by-step explanation:
Based on the provided audio, there is no exact answer given to who Bárbara will visit next year. The question seems to be referring to a comprehension exercise that would normally accompany an audio track, which is not available here. Therefore, I cannot provide a definitive answer to whether Bárbara will visit her grandmother, her grandmother's relatives, her great grandparents, or her great grandparents' relatives. However, in the context of family and generational discussions drawn from literature and anecdotes, it's clear that family connections across generations, as exemplified by grandmothers and their stories, deeply influence individuals and shape their experiences.
