The speaker in each poem has a specific point of view, or position about the subject matter of the poem. Tell one way the points of view are similar and one way they are different. One way the speakers' points of view are similar is that both feel isolated.
The Poet uses litotes as a literary technique in the sentence That [sword] was not useless to the warrior now from Beowulf.
Litotes is a technique that communicates in a positive message through a negative structure, we can see in the sentence the use of was not, but the general meaning is a positive one saying that the sword was in fact really useful.
The other options are not correct because those techniques make reference to sounds and metrics or use of a combination of words no the general meaning of a sentence.
