In the first paragraph of Passage 1, how does the author mainly support the idea
that the Norse lived in Greenland only
temporarily?
by providing dates indicating when the Norse
arrived in Greenland and when they left
by indicating the size of the population in
Greenland before the Norse vanished
by suggesting that many key details about
the Norse civilization in Greenland are still a
mystery
by describing what Icelandic literature
reveals about how long the Norse remained
in Greenland
