Answer:
What this passage tells us about Nick is:
C. He is wealthy enough to live in West Egg but not wealthy enough to rent a very nice place.
Step-by-step explanation:
Nick is impressionable enough to call his own house an eyesore and to think of the proximity of millionaires as "consoling". Therefore, we can eliminate option A. Option B is also wrong because there is nothing in the passage to reveal his desire to move to a different house. He likes it where he lives. Finally, option D speaks of desperation to become part of the elite, but Nick does not reveal that feeling at all. He is used to the company of wealthy people - perhaps not millionaires, but wealthy nonetheless.
We are left with option C. Nick comes from a well-off family. He does have some means, and he can afford to live in West Egg. However, he is not so rich as to rent a mansion. He takes a smaller house, one that has been overlooked, whose rent is affordable and that offers the perks of living in a great neighborhood.
