Migration refers to the movement of living organisms from one place to another.
Food consumption plays a vital role in migration. When animals are in particular habitat, they are already adapted there, there's a food chain and they already know how and where to get their food.
Relocating to a new place can affect this, and they have to adapt again and look for what to eat etc. Therefore, the essential question that Enzo should ask about the migration of the Canadian goose is that "what do they eat?".
I think the answer is characterization (I originally said plot but I just realized that I made a mistake when I was reading. Sorry about that! Hope I didn't mess anything up for you.) :D
The battle had taken place at the battle hall as Grendel’s
mother took Beowulf there in which is owned by someone and that Grendel’s
mother inadvertently give Beowulf the advantage because the water that is
present in the battle hall didn’t hurt Beowulf.
