Why do you think King Hrothgar's men won't challenge Grendel?

Genrish500 [490]

Answer and Explanation:

Hrothgar and Grendel are characters in the famous epic poem "Beowulf". Grendel is described as a man-eating monster, void of feelings and empathy. However, <u>none of King Hrothgar's men is willing to challenge and defeat Grendel. The reason for that is the fact that they believe Grendel will certainly kill them if they challenge him. The King's men think "distance [is] safety". Only those who fled survived Grendel's fury. Therefore, they are not willing to risk their lives. As we know, it is the hero of the story, the warrior Beowulf who will kill Grendel.</u>

The poem describes Grendel’s mother’s underwater lair in great detail in lines 422–440. Select three key details about the lake

Alborosie

Answer:

The lake is described as dark, gloomy and disgusting.

Explanation:

Grendel's mother lives in an underwater lair in a set of lakes and swamps that is described in an uncomfortable and unpleasant way. Lines 422-440 describe this place as an environment formed by decomposition, rot and darkness and show the lake as a very unpleasant place. This contributes to increasing the inadequacy tone and provokes, in the reader, a feeling of regret in relation to Grendel and his mother. In addition, this environment reinforces the concept of disorder, caused by the two monsters.
