Answer:
-A strange chillness, whether the body or spirit they could not tell, was creeping gradually over them all. They gazed at one another, and fancied that each fleeting moment snatched away a charm.
Explanation:
An allegory is, in this sense, an artistic theme or a literary figure that allows us to represent an abstract idea through other forms, these being human, animals or objects. In this case, the phrase "be the body or the spirit" is an allegory because it represents something other than its actual meaning.
