In a response of two to three sentences, explain how the action described in the following lines show grendel as a monster. (20 points) "'neath the cloudy cliffs came from the moor then grendel going, god's anger bare he. the monster intended some one of earthmen in the hall-building grand to entrap and make way with"

As for me,  after reading those lines that you shared, I can clearly see that  the God is really furious about Grendel and I think that the first sentence reveals this. Author shows the contrast between characters, because God definitely would never release his anger on character like Beowulf and it is made in order to emphasize that  Grendel is not just compared with monster (that is mentioned above), she really is.
