Explanation
In this sentence, there are four errors:
one is related to the use of incorrect verb form;
the second is related to the use of articles;
the third is related to the use of relative pronouns;
the last is related to wordiness.
Error 1: Incorrect Verb Form (“having been perpetuate”)
Error 2: Unnecessary “the” Before “Societies”
The word “societies” is a general plural noun, so “the” is not needed unless referring to specific societies.
Error 3: Incorrect Use of “Which” Instead of “Who”
The relative pronoun “which” is used for things (objects, ideas, animals).
The experimental novel—which blends elements of poetry and prose—is a challenge to traditional notions of storytelling and narrative structure, but it will be widely accepted by the time it is recognized as a masterpiece.
Explanation In this sentence, the error is the incorrect use of “Will Have Been” (Future Perfect Tense). We use “will have been” (future perfect) only when emphasizing that action will be completed before another future event.
