Final answer:
Option (b) 'kills; forever' is the correct answer to complete the sentence 'A warrior ______ a gruesome monster ______.' because it indicates that the monster is defeated permanently, which is consistent with traditional narratives of warriors defeating monsters.
Step-by-step explanation:
The question "A warrior ______ a gruesome monster ______." is meant to be completed with the proper word pair to construct a meaningful and grammatically correct sentence. From the given options a, b, c, and d, the most fitting answer would be option (b) "kills; forever." This pair of words conveys the finality and decisiveness of the warrior's action against the monster, indicating that the monster was defeated in such a way that it will not return, which aligns with traditional narratives involving warriors and monsters.
The word warrior refers to a fighter, often one engaged in battle within a historical or fantastical context. The term gruesome describes something that is horrific or shockingly repellent, which is apt for describing a monster within the stories these words often appear in. The word forever conveys a sense of eternity, suggesting that the monster will not come back to life or be a threat any longer.
In literature and narrative contexts, it's common for warriors to confront and vanquish monsters, and saying a warrior kills a monster forever fits into this classic trope. Therefore, this option completes the sentence in a way that is both logical and consistent with many traditional stories and myths.
