In lines 20-21, the narrator states that many people have perished while journeying to the North Pole: “Nobody has suc-ceeded in this thing, and many have died.”
Choices B, C, and D are incorrect because the narrator does not indicate that previous explorers have made surprising discoveries, have failed to deter-mine the exact location of the North Pole, or had different motivations than his own.
