Explanation:

There are some different ways in order to look for a book in the library in an easy way, depending on the information that we could have in our hands about it.

The card catalogs are the documents that contain the most relevant information about the books that it is possible to find in the library, and they are classified according to three different topics as follow:

1. Subject card

2. Title card

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.)
