Funny story; When I was in university, as a Fresher, people kept asking me things like "have you seen the fox/ university fox/ lovely fox yet". It was some months later before one night I saw a fox running across the pitch on my way home. All that time I spent looking for the fabled pretty girl was a waste!
Well the sentence generates a lot of posts, but actually it's the sentence that's wrong. I assume DL wants us to learn 'relativamente' so, put it in a sentence that someone might use. 'El vino es relativamente fuerte' for example. Then we wouldn't all be trying to circumvent the program by throwing in alternative words to make the sentence into something that we might just say.
