Which best explains what it means for a poem to offer a "glimpsed moment"?
a. poetry often reveals a brief but telling aspect of a larger story or
idea.
b. poetry is primarily visual and includes details that appeal to the
eyes.
c. poetry generally should not be longer than a single manuscript
page.
d. poetry intentionally conceals the truth from the reader.

The correct answer is option A. Poetry often reveals a brief but telling aspect of a larger story or  idea.

Explanation:

Poetry is that literary genre that always had an appeal for the correct choice of words to tell a larger type of story or idea than the one it is expressed, where the reader can interpret it in their own way.

Most authors reveal in their poems something that they do not write explicitly, but they hide it between metaphors, rhymes and verses so that we as readers realize what it really means.

We have thousands of examples of this, but let's think of one of the best known as the poem The Raven written by Edgar Allan Poe. This poem shows a raven who comes to torment a man saying "Nevermore", but in reality the message behind that is that the protagonist does not want to face his own thoughts in which he has to accept that his beloved has died and will never see her again.

That is the "hidden" idea, the author does not expect us to think that a raven speaks, but to think beyond what is written.

Therefore, the correct answer is option A.

faith or loyalty when pledged in a solemn agreement or undertaking.
