In the first sentence, there is "Baccaulauréat" in the answer, but the clue is "Baccalauréat."
I am also unsure about the use of the singular "siècle" in the last sentence since you do not have "siècle" after XVIIIe. Shouldn't the English be "Between the end of the 18th and middle of the 19th Centuries."? or "Between the end of the 18th Century and the middle of the 19th Century."?
