On november 26, the japanese attack fleet of 33 warships and auxiliary craft, including six aircraft carriers, sailed from northern japan for the hawaiian islands. the fleet followed a route that took it far to the north of the normal shipping lanes. by early morning, december 7, 1941, the ships had reached their launch position, 230 miles north of oahu. at 6: 00 a. m., the first wave of fighters, bombers, and torpedo planes took off. which best identifies a key concept and explains how it is developed?

The excerpt describes the attack on Pearl Harbor. The key concept begins from the first sentence and the narration exactly shows how the story is going to be unraveled. After that, the description continues. In a nutshell, the information contained in the first sentence about Japanese attack is the answer of this question.

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.)

your answer would be: c
