<em><u>Answer:</u></em>
D. A central idea is often stated directly, while a theme is usually only suggested.
<em><u>Explanation:</u></em>
A theme is uncovered by portrayal or plot, while a central idea is uncovered by rhetoric or an immediate articulation.
A theme is the focal point of a content. It is made through the plot of the story, the characters and the setting of the story.
A central idea is the central matter that the story needs to pass on. It is normally uncovered legitimately, or by utilizing techniques for talk and influence. Stories are worked such that help the focal idea.
The answer is A. Ethos means it appeals to credibility.
In this poem we can see the comparison of two points of view about one subject, in the first part of the poem, the speaker is in a lecture of an apparently very successful astronomer, where he sees charts, equations and numbers that represent many aspect of the stars, the speaker gets bored and doesn't seem to find any of this information interesting, so he goes out and sees the stars in the night sky and realizes that he doesn't need to understand all the numbers an science behind them to be able to appreciate their beauty.
So basically the romantic ideas are that even though the astronomer finds his/her passion in the science, to the writer, the science distracted him from the beauty of the stars themselves
The structure of the poem reinforce this idea, first by using contractions as learn'd, wander'd, the writer wants us to realize that the speaker doesn't have an educational level as high as the astronomer. Also, at the beginning of the poem, it is basically a description of the lecture told without much excitement otherwise, when the speaker goes out, the description became so much full of emotion, ex: In the mystical moist night-air..
