One good question to ask yourself during the editing process is,
""

A. Did I include commas where needed, and/or did I
use commas correctly?

B. Did I make sure that my speaker tags include
details that help readers understand my characters?

C. Did I include enough detail about the setting to
help readers picture it in their minds?

c. to depict the cunningness of the federal soldiers

the sentence that best describes the tone of the passage from the radio broadcast compared to the passage from the book is b. the radio broadcast has a more surprised tone.

consider the text evidence: in the passage from the book, the description is more matter-of-fact. it is simply describing the things resembling little grey snakes, but there is no urgency in the description. on the other hand, in the passage from the radio broadcast, there is definetely urgency (you can tell from the expression used, "good heavens", which clearly indicates surprise.)

comfort   in their suffering
