Three questions about England (including the obscure Wedmore treaty, that only 1% knew about), and only two about the much more greater and influential Carolingian Empire, doesn't make a balanced test.
Might you suggest questions about this aforementioned empire? I'm afraid that, while the Carolingians had greater influence at that time, no noteworthy events occurred.
Alfred the Great, the Venerable Bede and Beowulf too obscure for you? I'd never heard of Wedmore, but am familiar with the Danelaw and I think more would get it if it were re-worded. I thought this was a good test of general historical knowledge of this period. There are plenty of quizzes on pop culture and Harry Potter if that's more your thing...
