text_A: Europeans probably became aware of Greenland's existence in the early 10th century, after Gunnbjörn Ulfsson, while sailing from Norway to Iceland, was blown off course by a storm and sighted some islands off Greenland. During the 980s explorers led by Erik the Red set out from Iceland and reached the southwest coast of Greenland. They found the region uninhabited, and subsequently settled there. Erik named the island "Greenland" ("Grœnland" in Old Norse, "Grænland" in modern Icelandic, "Grønland" in modern Danish and Norwegian). Both the "Book of Icelanders" ("Íslendingabók", a medieval account of Icelandic history from the 12th century onward) and the "Saga of Eric the Red" ("Eiríks saga rauða", a medieval account of his life and of the Norse settlement of Greenland) state that Erik said that "it would encourage people to go there that the land had a good name"."
text_B: Given the Vikings' well-known reputation as marauders and invaders, would you say that settling into Greenland was somewhat uncharacteristic (at least, compared to that historical stereotype)?
NO.
