The image that best conveys an eerie mood is B. "...groping among the tombs and invading the privacy of the dead,..."

What is an eerie mood?

An eerie mood creates a scary feeling in the reader.

Using setting techniques like sights, sounds, smells, thoughts, emotions, tastes, etc., the author aims to scare, overwhelm, or threaten the reader's calmness.

For example, how can one grope among the tombs by invading the privacy of the dead, perhaps, at night?

The eerie mood that the image above conveys shows that the narrator is engaged in something sinister, connoting evil intention.

Thus, the image that best conveys an eerie mood is Option B.

paragraph that lays out your argument, body paragraphs that develop your thesis,
and a conclusion paragraph that wraps up your argument. (30 points)

Answers

1892: The Yellow Tapestry is the concealed diary of a woman compelled to undergo country rest therapy for a "nervous condition." It was PPD. They forbade her from writing and prescribed absolute inactivity. Beyond the hypnotic weaving of the faded yellow tapestry, the protagonist creates her own life. The Yellow Tapestry stands out for the strength of its witness to women's need for independence and self-empowerment.

The protagonist feels trapped by her life, her spouse, and everyone around her as she spends more and more time in the chamber her husband has provided her. Can't stop glancing at the wallpaper. She sees a woman behind bars trying to escape from her.

As the only protagonist, the reader only knows the narrator from her diary entries. The story's message is confined within the narrator's thoughts, not her spouse or his sister.

The woman exposes more about herself and her environment. He rejects any concerns or ideas that she may have, claiming that he knows more about what is convenient for her as a doctor, and calling her names given to a girl.

Even though the story is short, it is full of vivid imagery. There's a panicky feeling in the air and a want to get out of that horrible yellow tapestry. When she loses herself in the patterns, she believes there is someone beyond the tapestry mocking her from a similar jail. You're paralyzed by the end. With a sad tone, you sympathize with the protagonist. This is a horror story. In the end, the reader must decide if the words on the yellow paper are metaphorical or real. Similarly, did the heroine go insane, or was it all in her head?

Reread the first two paragraphs of the passage.

How does this opening section develop the central idea of the passage?


It explains how Douglass comes to understand that white people take advantage of ignorance to keep black people enslaved.

It shows that Douglass is a quick learner and sets the stage for the passage's exploration of how Douglass learns to read.

It shows the mean-spirited attitude of Mr. Auld and sets the stage for the central idea: the cruelty of white slaveholders.

It describes Douglass's relationship with Mr. and Mrs. Auld and introduces the central idea: Douglass's resentment of Mr. and Mrs. Auld.

Answers

This opening section develops the central idea of the passage because:

1. It explains how Douglass comes to understand that white people take advantage of ignorance to keep black people enslaved.

Born in 1818, Frederick Douglass was a former slave who became one of the greatest names in the abolitionist movement and in American literature.According to his memoirs, as we can see in the passage in the document you have attached, Douglass first started learning how to read and write from his owner, Mrs. Auld.However, her husband forbade her to continue his education for the clear and awful reason that an educated slave would no longer keep on being a slave. Mr. Auld is well aware that, to be able to exert such type of unfair power over someone, one must keep that person ignorant. If Douglass learned things, he would understand the injustice of what was being done to himself and others, and he would fight against it.Thus, we can conclude that the first two paragraphs convey the idea that white people, such as Mr. Auld, took advantage of slaves by keeping them uneducated.
