They had ..... large villages of houses built close together.
1. beautifully2. beautiful3. beautified4. beauty

I have problem with this kind of question. I don't learn when we must use adjective before series of adjectives and nouns and when we must use adverb. I thought that "beautiful large villages" would be considered as this form : Quality + size + noun. However it seems that we need adverb here. WHY? please illuminate this tough topic for me a bit.
