Excerpt from Norse Mythology Part B
Kate McConnaughey

(11) Until Baldur stepped from the rainbow-bridge to the earth, he saw a king’s daughter so beautiful that he fell in love with her.
Which adverb would be the correct revision for the word until at the beginning of sentence (11)?
A) Because

B) Meanwhile

C) When
D) While

c

Explanation:

unless theres a second plot to the story before point 11 i believe it would be When, otherwise meanwhile could work

the answer should be d) he was one of those young thousands who greeted the war with a certain amount of relief, welcoming the liberation from webs of tangled emotion" since it is the best option because it shows his desire to free himself. 

hope this answer you! have a great day.
