Why is incorrect to say, "Fueron vacaciones geniales"? According to the quiz, one must say, "Fueron unas vacaciones geniales"
You need the article "a" in plural: "unos/unas", the same way you need it in English: "It was a great vacation". It would be incorrect to say "It was great vacation". The same applies to the Spanish sentence, you cannot omit the article.
I hope this helps,
