The narrator restarts the fire by blowing on the embers
Explanation:
The narrator kneels and blows, by saying that the fire flickers, it would mean that it was not previously lit, hence, the narrator is restarting the fire.
The second sentence shouldn't start with Since because Since is a word to combine sentences like because combines sentences. They are conjunctions I believe.
Your answer would be closing because Jenna is letting someone know that she expects a call from whoever she is talking to otherwise, they would respond back to her
