Which sentence states a fact about ostriches? A They are not ordinary birds.
B Their feathers are beautiful.
C They are remarkable birds.
D They eat what they find.

they eat what they find

Explanation:

in my opinion, the first three appear to be opinions rather than facts.

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.)

a simple sentence must have at least one dependent clause.
