Answer and Explanation:

Adverb clauses function as an adverb, modifying an adjective, a verb, or another adjective in the sentence. They can indicate manner, location, time, cause, concession, degree, and reason. Adverb clauses must present a subordinating conjunction. With that in mind, let's combine the clauses below by transforming one of them into an adverb clause:

1. I put my complaint on paper. I felt much better.

After I put my complaint on paper, I felt much better.

2. Dan has a good memory, and he can learn his part fast.

Because Dan has a good memory, he can learn his part fast.

3. The flowers appeared to vanish. The magician pulled away the scarf quickly.

The flowers appeared to vanish when the magician pulled away the scarf quickly.

4. We need to reach the airport on time. Our plane may take off without us.

Unless we reach the airport on time, our plane may take off without us.

5. I moved from the end of the row to the middle. I could see the speaker more clearly.

Since I moved from the end of the row to the middle, I could see the speaker more clearly.
