Hello. You did not inform the article to which this question refers, which makes it difficult for it to be answered accurately. However, I will help you in the best possible way.
It is right to make a decision when you feel the need to defend something you believe in, or when you need to change a situation. This must be done taking into account respect and calm, so that the positioning is effective. In this case, before taking a position it is necessary to analyze the whole situation, promoting the understanding of the points of view until it is necessary to choose one. This should not be done in a hurry and based on emotions, but based on reason.
B because in order for the story to be non-fiction it needs to be real and based on true facts
<em>a documentray video</em> would be the best option. i diagram can be the first one taken away because a diagram won't be effective if you would want to include armstrong's music. an essay is another option that can be taken away as well, since an essay won't be effective for showcasing armstrong's music as well. radio program would be the last option taken away. as a student who is doing a project, a documentary video seems the most realistic for a student. radio programs would most likely be unatainable to a student.
so, your answer would be <em>c.) a documentary video</em>
