The only adverb in A is "sometimes"; it modifies the verb "is called".Originally Posted by klynne
In B, the first part is a typo. In the rest, "then" is an adverb. I would also call "down" an adverb, though some might have it as part of a phrasal verb "write down". In addition "through the form" is an adverbial prepositional phrase, modifying "go"..
