Please study these carefully from the above sites.

"Recognize an adjective clause when you see one.
An adjective clause—also called an adjectival or relative clause—will meet three requirements:

First, it will contain a subject and verb.
Next, it will begin with a relative pronoun [who, whom, whose, that, or which] or a relative adverb [when, where, or why].
Finally, it will function as an adjective, answering the questions What kind? How many? or Which one?

Adverb clauses begin with subordination conjunctions
after, before, until, while, because, since, as, so that, in order that, if, unless, whether, though, although, even though, where.


Number 3 is a little tricky. The clause is the direct object of the verb. What do you think it is now?
A?

Oh, can you tell me if the first two i answered were wrong too? Thanks
-MC
My bad my bad. For #3 I meant, i think it's B
-MC
You haven't answered the first two right, yet.

For 3, direct objects are not either adjectives or adverbs.
Must be C

d
c
