Lucked out on this one. I didn't know the answer to the Chinese dynasty question, but it matched first 3 letters of a later question, so I got it anyway.
This series of quizzes are great, but the way my brain processes history, it's odd to me how they start from the most recent events and work their way back, so I always start from the bottom and work my way up. As such, on this quiz, "Hanoi" also winds up giving you "Han".
(No spoilers here). I didn't know the Chinese Dynasty, so I was going to come back to it. In guessing the city on the Red River, I got the dynasty answer - and I went on guessing Asian cities for the Red river city, even though technically I had it already. I think, even though individually they are both great questions, I think one of them has to be changed, or eliminated. Maybe "The capital of this modern Asian country, on the Red River, was once the capital of the Au Lac kingdom" with the answer being the country, not the city?
I dont think it's due to that, just this website is mainly of US audience which naturally are more likely to know about European history than Indian. I am European and I knew the answer, as well as all other Asian questions in these quizzes.
Please accept Halley. Also, Han is given when writing Hanoi, you could reword the question as "The capital of this modern-day country is established as ...".
