Answer:
The correct answer to this open question is the following.
This is a statement. It has no question at all. Probably the question should be "Why did the historical account of the Viking change?
If this is the case, then the correct answer is "Researchers analyzed evidence to discover that a Viking buried with weapons was female."
This new study created some controversy in that, traditionally, historians had believed that Vikings warriors had been only men. Women had other functions and activities in Viking's societies. So when the results of the 1970 study were published, it made historians believe that if the body found in the tomb was a woman body, then there should be many other women at that time that were warriors too.
Step-by-step explanation:
"Researchers analyzed evidence to discover that a Viking buried with weapons was female."
