Final answer:
The complete sentence with a tag question is 'Nothing satisfies him, does it?'. This rhetorical device is used to emphasize the universality of dissatisfaction and internal struggle in the given context, inviting the reader to reflect.
Step-by-step explanation:
The question 'Nothing satisfies him, ...?' is asking for the addition of a tag question to complete the sentence. A tag question is a short question added to the end of a statement, usually to seek confirmation or to invite the reader or listener to agree with the statement made.
The appropriate tag question to add is 'does it?' which turns the statement into 'Nothing satisfies him, does it?'. This reflects a tone of consensus-seeking or invites reflection on the part of the reader or listener.
Considering the contextual passages provided, the sentences describe characters dealing with profound dissatisfaction, presenting examples of individuals wrestling with internal conflict, whether it be the man tormented by his feelings towards his children or the hunger artist frustrated with being misunderstood by the audience. The usage of a tag question here rhetorically emphasizes the universality of dissatisfaction and internal struggle, prompting deeper contemplation.
