<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>
<span>The correct answer is B. Ralph and them are waiting for us at the metro station. It is a nominative case pronoun because them is here used as a subject, that is, the doer of the action, so it is nominative. The rest are either objective case or dative because the forms are things like him instead of he which answers the question of to whom instead of who.</span>
