So you can "read in between the lines" so to say, Teachers want you to re-read what you have read to develop a deeper understanding.
Answer:
O In his day, he was the mightiest man on earth
Explanation:
The poem describes Beowulf as battle-brave, a strong warrior who had the strength of thirty men. Beowulf was able to undergo the quest of defeating Grendel because he was the only courageous and bold man in his day who was strong enough to challenge Grendel in a battle.
The evidence of his mightiness can be seen in the fact that he defeated Grendel and put him to death. When Grendel's mother also came to avenge his death, Beowulf also defeated her.
B. Overgeneralization
They are saying that "practically every teen cares" but have no real evidence to back that up. They may have polled a small group of teenagers and because the majority of them said they care about animals they generalized that information to represent everyone in the age group. Without a full poll or teens there is no way to know how many do or do not care about the welfare of animals.
It guides the planning, research, and writing of the essay.
