Answer:
A Despite not explicitly discussing Hughes or his poetry, King etc.
Explanation:
As the title <em>Langston Hughes' </em><em>Hidden influence </em><em>on MLK </em>clearly shows, the central idea is the non-visible (at first sight) influence of Langston Hughes on MLK. Due to the fact that MLK didn´t explicitly discussed or mentioned L. Hughes, his influence is, therefore, hidden.
A Second Major Plot Point
The correct answer is: It is more easily understood by the reader.
When Thomas Jefferson gave the speech on The Declaration of Independence he had appealed to the people by giving them something that's clearly understandable and something that they can agree or disagree to on some degree.
Thomas Paine on the other hand was not specific on the speech and gave jargons and stories that only he and the government can understand and not of the people.
Jefferson's appeal is more effective because he understood the plight and the sufferings of his people, and that freedom is something that all humans can achieve in any society to which they belong to.
An author might chose a first person narrator, because the first person narrator has a first person view of whatever the story is talking about. So a first person narrator makes an author more reliable and makes the story more personal.
