In "The Black Cat," the narrator begins the story by speaking directly to the reader. The narrator continues this practice periodically throughout the story. How does the author use this structure to create mystery in the story?

The author creates mystery in the story with the help of a narrator that describes everything that he experienced with "Pluto" the black cat.

Explanation:

One of the strategies of the author to catch the reader attention is the name of the story "The Black Cat" when people starts reading it they imagine that the black cat, is an important character in the story. However, the narrator begins the story by giving many details and he says "he has many pets" and he also says "he never mistreat any of his pets" so people can take a picture of what's going to happen then. So the reader keeps reading in order to know the mystery about "Pluto". After knowing that the narrator has "alcohol problems" we come to the conclusion that something bad is going to happen to the cat.

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !
