As we know, an adverb is characterized as a word that functions to describe or modify an adjective, verb, or another adverb.
As per the question, <u>the given sentence employs an 'infinitive adverb' i.e. 'to go' because this non-finite verb is functioning to modify the main verb 'allowed' by adding details about it.</u> It answers the question 'allowed what?' by replying 'to go.' It cannot be participle as there is no use of participle in the sentence except for the main verb and hence, options A and B are incorrect. Option D is incorrect as infinitive is not employed as an adjective to modify a noun. Therefore, <u>option C</u> is the correct answer.
He is wealthy enough to live in West Egg but not wealthy enough to rent a very nice place.
Nick describes his place as "an eyesore". This detail shows us that the place he's renting is not nice in comparison to the other homes in West Egg. We also know that he must have some wealth in order to afford to pay eighty dollars a month during this time period. From this excerpt, there is no indication that Nick's choice to live in the small house is temporary or that he seems desperate to become part of the elite society. He may be impressed by material wealth because he describes the proximity of the millionaires as "consoling", so option A is also not a good choice.
