An interjection can be more than one word
Words such as 'bleak', 'dying', 'wrought', 'ghost', and 'sorrow' create an ominous and spooky atmosphere in "The Raven". These words have negative connotations, meaning that the words sound dark and frightening to the reader. For instance, if you wanted to create a spooky atmosphere in the following sentence, you might replace the verb with another word that has a more negative connotation.
A chill passed through the room.
A chill crept across the room.
While both sentences mean essentially the same thing, the second sentence sounds scarier because the verb has a more negative connotation.
Hope this helps!
The article is a argumentative tone/mood. Evidence of this is when the author wrote "NASA’s space program is worth preserving at any cost."That shows how they personally believe that it is worth preserving and that they’re trying to prove their opinion is valid. Also when the author says"It is impossible to list all the benefits of a thriving space program." The author has a strong opinion that they believe which makes it argumentative.
