"It is neither good nor bad."
I don't understand..I thought いい was "good" and よくmeant "often"? Shouldn't it be いいもわるくもないです。?
よく is the negative form of いい. It's irregular and you gotta memorize it, unfortunately.
Needs another も, the answer states two but you only get one も to choose from so you can only make, 良くも、わるくないです
I had the same question about the second も. I don't know enough Japanese grammar to judge so was hoping someone else could clarify.
The multiple も make the items into a list, and instead of negating each item individually you can just negate the whole block at the end with ない.
[Aも] = [Also A]
[Aも][Bも] = [Also A] and [Also B]
[AもBも] = Both [A and B]
[AもBも]ない = Neither [A and B]
I typed in 良くも悪くもないです and it was not accepted. I came across the same problem in お箸 for "chopsticks". Hope duo can fix it XD
