Historical help

Thos eof you who studt/follow British history might be able to help me with this. I've been watching "The Seven Ages of Britian" and found an online quiz that corresponds to each episode. I just can't get the last question and it's driving me mad. I'm posting the link here in the hopes someone can help me.

In case the link doesn't work, I'll post the question.
