What does accompaniment mean

There are two answers.

Explanation:

As quoted from Google, this word could either mean "a musical part that supports or partners a solo instrument, voice, or group" OR "something that is supplementary to or complements something else, typically food".

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.)
