Archaeologists have firm evidence that Norse explorers reached the coast of North America around A.D. 1000, long before Christopher Columbus first voyage to America in 1492. Some people claim to have excavated Norse weapons dating from the 1300s in areas far inland from Norse coastal sites. If these claims are true, then the Norse must have explored the interior of North America, as well as the coast, before Columbus first voyage.
Which of the following is an assumption on which the argument depends?
A. The sites where weapons were found were the locations of relatively permanent Norse settlements.
B. The Norse weapons were not brought by Native Americans to the sites where they were excavated.
C. Norse explorers were more likely to travel far inland than were later explorers of North America.
D. Norse explorers would not have made expeditions far inland in North America without weapons.
E. The design of Norse weapons did not change significantly between A.D. 1000 and A.D. 1300.
