I dont understand the question can you explain it more
<span>The correct answer is the final sentence. The final sentence of this paragraph -- Ben sighed with satisfaction as he finally reached his trailer and opened the front door -- indicates that Ben likes living in Happy Trails Park. The other sentences illustrate that this is nice place to live: there are well-tended gardens, beautiful flowers, etc. However, only the final sentence proves that Ben is happy there, because we are told he "sighed with satisfaction" upon reaching his trailer.</span>
The first one means that you tried to stop feeling nervous or you tried to swallow so much that you couldn't.
The second one means that you are getting more nervous, or anxious.
