What can you do to avoid the plague? The answer is: very little. Although there are no fewer than twenty-three medical treatises dedicated to it by 1600, including hundreds of recipes for medicines, none of them will help you. Nor will perfuming your room and airing it with fire save you—despite this being the official advice of the College of Physicians. –The Time Traveler’s Guide to Elizabethan England,

What tone does the passage most clearly convey?

Which phrase most clearly contributes to this tone?

In what way is this tone most effective?

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.)
