provide a written description of the complement of the given event

At least one of the textbooks is free of errors.

In statistics, the complement rule allows us to connect the probability of an event with the probability of the complement of an event. This is done so that, if we know the probability of one of these two, we can find out that of the other. In this case, the complement of the given event (when several textbooks are edited, none of them are found to be free of errors) is: At least one of the textbooks is free of errors.

arah orne jewett first published "a white heron" in her 1886 collection, "a white heron and other stories." this short story tells the tale of what happens when sylvia, a 9-year-old girl living deep in the forest with her grandmother, meets a young hunter looking to capture, and kill, the white heron living in sylvia's woods. the climax occurs when sylvia must decide whether to him or protect the bird.

rising action

leading up to the climax of the story, the nameless young hunter befriends sylvia and her grandmother, mrs. tilly. he explains to mrs. tilly that he is bent on "stuffing and preserving" a little white heron that he believes lives near their cottage. mrs. tilly offers up that "[t]here ain't a foot o' ground" that sylvia doesn't know and suggests that she may be able to him find the bird.

climax

after following, but not really , the young hunter on his search for the heron, sylvia slips out of bed alone in the middle of the night to find the heron for herself. perched at the top of a gigantic pine tree, sylvia spots the heron, and its nest, in a dead hemlock tree across the way. the following morning she returns home to find her grandmother and the hunter waiting for her at the door. in the moment when she plans to tell the hunter where to find the heron, she suddenly decides to protect the heron and remain silent; even the promise of much needed money does not sway her.

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.)
