I think it is c because a rhetorical question is <span>a question asked in order to create a dramatic effect or to make a point rather than to get an answer.</span>
I think its the word expensive because adjectives describe nouns
It depends what you are writing,some can be factual/informal,others persuasive ect
A phrase is a set of words that don't have a subject doing a verb.
A clause does have a subject doing a verb.
So therefore, 1 would be a phrase, 2 would be a subordinate clause, and I'm sure (or hope) you can figure out the rest..?
