How can the reader recognize the particular voice of a story

answer: b. grete might have remained as shy and immature as she was at the beginning of the story.

one of the most interesting characteristics of gregor's metamorphosis is that, although he is the only character who has physically changed, it is this same change which triggered a transformation in the rest of his family.

by taking care of gregor, grete has become stronger and more confident. she has found a life outside of the house, and has become more independent and self-sufficient. the novel implies that the trigger for the change is gregor's own transformation, and that without it, grete was likely to remain as shy and immature as she was at the beginning of the book.

explanation:

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.)
