A shift in thought can be indicated by what is called an em dash. An em dash is used to set of an interruption that is closely relevant to
the sentence but is not grammatically part of it. These set of
interruptions can be found in a list, illustration, restatement, shift
in thought or tone, summary, or dramatic point.
Hope this helps, if you need anymore help or further explanation just let me know!! :)
Agreed because the other ones wouldn't make sense
I would say that the writer is using either personification or metaphor. However, I find B. personification to be the most logical answer.
The correct answer is A. Your teacher wants you to examine how point of view influences hero selection
Explanation
Newspaper articles are primary sources of information because these documents report important events in an objective way for the knowledge of the general public. In addition, they serve to know first-hand events of the past. In this case, the teacher gives his students articles from Japanese and American newspapers to write an article on the attack on Pearl Harbor.
An interesting aspect of this activity is that the vision of both articles is different because each author has a different point of view about the event of Pearl Harbor. In this case, each one points out the soldiers or military personnel of their country as heroes because they share its ideals of struggle.
This activity is quite important to investigate because it allows students to know about an event through different points of view, and also learn more about it and have a broader vision of what happened.
So, the correct answer is A. Your teacher wants you to examine how point of view influences hero selection
