Well, this really depends on the word or words that are italicized. However, I did find somewhere on the Internet that the italicized words are <em>before the concert was over.
</em>If that is the case, then the correct answer is adverbial clause, given that it functions as a simple adverb, that is, it answers the question - when did something happen?
<em />When did we leave the auditorium? - Before the concert was over.
Answer:
<em>My car looks brand new with its rusted fender and dented doors.</em>
Explanation:
Sarcasm is when someone say something opposite to the actual scenario, to mock something just to make it funny in a delighted way of humor. <em>"My car is brand new"</em> is totally opposite to <em>"it's rusted fender and dented doors". </em>
Clearly his car is old, has rusted fender and dented doors which means poorly managed, but he for the sake of laugh or to make it funny mentioned it a brand new car.
