I have found this question online and realized that "ice" should actually be "eyes", which makes more sense with the context of the sentence.
Answer:
The entire absolute phrase in the sentence is "eyes glittering with concentration".
Explanation:
After reading it, we realize that "eyes glittering with concentration" refers to the sentence as whole. That is what makes it an absolute phrase - instead of modifying just one noun, it modifies a whole sentence. In this case, we can imagine Jack moving his cursor while his eyes glitter, showing how focused he is.
Absolute phrases' structure include a noun or a pronoun followed by a participial phrase. For example: hands trembling with nervousness. Notice that "eyes glittering with concentration" follows that structure.
Participial phrases consist of a participle and modifiers. For example: running out of energy.
Answer:
1. Beowulf sets out for his journey for Daneland.
2. Hrothgar welcomes Beowulf.
3. Beowulf waits for Grendel to attack Heorot.
4. Beowulf succeeds in defeating Grendel by decapitating him.
5. Beowulf fights with Grendel's mother.
6. Beowulf sets out for his Geatish homeland.
7. Beowulf sets out for his fight with the dragon.
Explanation:
Upon Hrothgar's requiest, Beowulf travels to Daneland to help the king get rid of the terrible monster named Grendel. The night after meeting with Hrothgar, Beowulf and his men wait for Grendel to arrive, after which he kills him with his bare hands. When Grendel's mother learned of his death, she fights Beowulf as an act of revenge and dies by his hand. Feasting ensues after which Beowulf and his men return to their home of Geat.
Years after these events, Beowulf becomes king in Geatland and has to defend his kingdom against a dragon who ultimately manages to defeat him in his old age.
