Final answer:
Squealer is using a rhetorical question.
Step-by-step explanation:
The rhetorical device that Squealer is using in the quote, "surely there is no one among you who wants to see Jones come back?", is a rhetorical question. A rhetorical question is a question that is not expected to be answered, and it is often used to create a dramatic effect or emphasize a point. In this case, Squealer is using the rhetorical question to convince the animals that no one wants to see Jones return.
