Final answer:
Sentence [2] contains a pronoun-antecedent error where 'it' should be replaced with 'his' to correctly refer to the human character Odysseus.
Step-by-step explanation:
- The sentence that contains a pronoun-antecedent error in the provided paragraph is sentence [2].
- In this sentence, 'it' is used as a pronoun for Odysseus, who is a human and should therefore be referred to by 'his' rather than 'its'.
- A corrected version of the sentence would be: 'It depicts the adventures of Odysseus as he tries to find his way home after the Trojan War.'
- Having human characters referred to by human pronouns maintains proper pronoun-antecedent agreement in English.
