This question asks us to select the most appropriate preposition to complete the sentence: "Volpone fell a victim ______ his own greed." To answer this correctly, we need to understand how the phrase "fell a victim" is typically used in English.

Understanding Prepositions in English Grammar

Prepositions are essential words in English grammar that show the relationship between a noun or pronoun and other words in a sentence. They often indicate location, direction, time, or cause. Correct usage of prepositions can sometimes be tricky as certain verbs, nouns, or adjectives are followed by specific prepositions, forming idiomatic phrases.

Analyzing the Phrase 'Fell a Victim'

The phrase "fell a victim" is part of a common idiom used to describe someone suffering harm, loss, or death due to a particular cause or circumstance. The standard way to express the cause in this idiom is by using a specific preposition after "victim".

The established idiom is "fall a victim to something". This structure links the victim to the force, cause, or thing that harms them. For example:

• Many trees fell a victim to the strong winds. (The winds were the cause).
• He unfortunately fell a victim to a scam. (The scam was the cause).
• The ancient city fell a victim to invasion. (The invasion was the cause).

In the sentence "Volpone fell a victim ______ his own greed," the phrase indicates that Volpone's greed was the underlying cause or reason for him suffering a negative consequence. Therefore, we need the preposition that completes the idiom "fall a victim to".

Choosing the Correct Preposition

Let's examine the given options in the context of the sentence and the idiom:

• to: This fits perfectly with the standard idiom "fall a victim to something". It correctly shows that Volpone's greed was the cause of his downfall or suffering.
• of: While we say "a victim of crime" or "a victim of circumstance," the structure "fall a victim of" is not the standard idiomatic way to express the cause in this particular phrase.
• about: The preposition 'about' usually indicates the topic or subject. "Fell a victim about his own greed" doesn't make grammatical sense and doesn't fit the idiom.
• for: The preposition 'for' has various uses (reason, purpose, duration, etc.), but it does not complete the idiom "fall a victim" to indicate the cause of the victimhood. "Fell a victim for his own greed" is incorrect in this context.

Based on the correct usage of the idiom "fall a victim to", the only appropriate preposition is 'to'. Volpone suffered consequences because of his greed; he fell a victim to his own greed.
