Answer:
Ignorance is the correct answer.
Explanation:
Emily Dickinson was an American poet, whose figure and role in literature is as important as Poe's and Whitman's. Even though she was a prolific poet, the vast majority of her works saw the light after she died.
In the poem, we can see the word darkness or dark in four out of five stanzas. The word has always been related to ignorance, being light the opposite and a synonym for knowledge. In the poem, we can see how the speaker mentions darkness as a natural part of life, such as ignorance, when she mentions that <em>We grow accustomed to the Dark</em>. In the third stanza, the speaker relates this darkness to <em>evenings of the Brain</em>, relating that part of the day to uncertainty and ignorance. In the fourth stanza, the speaker puts in the same level learning and the ability to see, contrasting these elements to darkness (where nothing can be seen or understood). In the last stanza, after the learning process of seeing, the speaker mentions that the <em>Darkness alters</em> or <em>something in the sight/adjusts itself to Midnight</em>, meaning that the object can gain knowledge or prefer to remain in darkness or ignorance.
