read the sentence.
it was not exactly what he had in mind when he agreed to do the task.
which word is the adverb modifying another adverb?

The word not modifies the word exactly.

Explanation:

An abverb is a word (or phrase) that modifies a verb (or adjective, or even another adverb). When modifying a verb, an adverb basically says how something is done.

Adverbs often end in -ly. We can spot the word exactly, which is describing the action of having something in mind. The word not, which is also an adverb, modifies the word exactly because it changes something about the meaning of exactly.

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.)
