Answer:
Rick: How <u>are</u> you and Marcia celebrate New Year's Eve, Tim?
<u>Will</u> you <u>both</u> go to any parties?
Tim No. We <u>will</u> go out for dinner. Our favorite restaurant
<u>will </u>serve a special meal, and our friends <u>would</u>
Join us there. But we <u>wont</u> stay out late.
Rick: So you <u>will</u> be home before midnight, huh?
Tim: That's right. It <u>would</u> be a quiet celebration.
Explanation:
I believe the answer is D (However) because C (Therefore) would not make sense as it means ‘for that reason’ or ‘consequently’, B (Then) is a time connective so that would not make sense as a transition word to connect the paragraph, and A (now) could be referred to as informal depending on how you use it, and it is commonly used as an adverb of time.
I hope this helped
