Explanation:
In the epic poem Beowulf, both good and evil are clearly defined. Beowulf himself embodies all that is good, but it's often expressed through his super-human capabilities. The monsters, including Grendel, his mother, and the dragon, all embody evil, and in fighting and defeating them, Beowulf is working to save not only the monsters' victims but the whole of humanity.
The italicized part if the sentence (vice president) is the predicate noun. A predicate noun renames the subject and follows a linking verb.
