First of all, which word is underlined. After I know which one is underlined, I can fully answer yous question.
Answer:
the suppression or prohibition of any parts of books, films, news, etc. that are considered obscene, politically unacceptable, or a threat to security
the suppression of speech, public communication, or other information, on the basis that such material is considered objectionable, harmful, sensitive, or "inconvenient"
can be conducted by a government, private institutions, and corporations
I would say that the line from Edgar Allan Poe's The Raven that provides information about the setting of the poem is:
<span>As of some one gently rapping, rapping at my chamber door.
</span>
Based on this line, we see that the setting is in a chamber.
