Final answer:
Midgard, in Norse mythology, was created from the flesh of the giant Ymir and not from an eyebrow. The correct selection is Option 1: No one's eyebrow is associated with Midgard.
Step-by-step explanation:
The question pertains to Norse mythology, and the creation of the world according to these ancient tales. Within these stories, Midgard, the realm of humans, was not created from someone's eyebrow but rather from the flesh of the giant Ymir.
The correct answer to the question, 'Whose eyebrow was turned into Midgard?' would be Option 1: No one's eyebrow is associated with Midgard. According to the myth, after the gods Odin, Vili, and Ve killed the giant Ymir, they used parts of his body to create the world; his flesh became the earth, his blood the seas and rivers, his bones the mountains, and his skull the heavens. However, there is no mention of his eyebrows being used to create Midgard or any other part of the world.
