There was a time when robots and home automation were just a fantasy. Robots were found only in
science fiction and home automation was limited to cartoon families who had every convenience at their
fingertips. Meals arrived with a simple push of a button. A robot maid performed every task humans
didn't care to do. Today, these once visionary ideas have become reality.
In factories, robots perform hazardous tasks; in homes, they vacuum the floor. Houses can now lock
themselves and lights are programmed to turn off and on automatically. In hospitals, doctors use robots to
perform surgery. Cars that drive themselves are in development. As automated machines and robots take
on more human tasks, there are serious questions to consider. What will become of society if robots do all
the work? Will humans become too dependent on machines and lose the ability to do things for
themselves? Will robots eventually become smarter than humans?

Explanation:

The first stanza of “On Being Brought from Africa,” introduces a paradox. Using evidence from the poem, describe the paradox.

Answers

Answer:

“On Being Brought from Africa”

Paradox in the first stanza:

Phillis described her enslavement as a means of her salvation.  Thus, she was brought to America so that her soul could be saved.  Those who enslaved her, saved her.  This ordinarily sounds difficult to understand and contradictory.  How can somebody who kill you make you alive?  This is a paradox which can only be appreciated in the light of the Christian gospel.  Christ died and rose again from the dead.  Because He has risen, He is able to save those who die in sin.

This is the central message of Phillis' poem titled "On Being Brought from Africa."  In her own words:

 "Twas mercy brought me from my Pagan land,

  Taught my benighted soul to understand  

  That there's a God, that there's a Saviour too:

  Once I redemption neither sought nor knew. "

Evil was turned to good in her life.  She was not complaining against her enslavement or being removed from her African root, friends, and family.  She eulogized God who has the ultimate power to bring about good from evil.  Though, she was not praising evil, she knew and therefore, understood, and greatly benefited from the evil done to her, and even appreciated those who did her evil for doing her good.

This should be the attitude of all Africans, including African Americans, and this should be how they must view their past.  Slavery was a condemnable evil.  But, God has turned it to good.  Africans should stop lamenting their past enslavement.  They should henceforth make themselves free and live in freedom.  They should not retreat to their past.  The past is history.  It is not the future of Africa.  They should appreciate that, though, enslavery derived them of temporary freedom, it has brought lasting freedom.  Freedom is only achieved in Christ Jesus, in walking the talk, and not in blaming the past or past actors.  Olaudah Equiano bought his freedom within three years.  For more than 50 years now, Africans have been in charge of their governments and their borders, but what have they achieved with the leadership?  They are still leading the people back to slavery in so many absurd ways.

Explanation:

Phillis Wheatley wrote "On Being Brought from Africa" in 1773.  She is recognized as the first African American woman to publish a book in English.

The paradox is that black people are seen as sinful beings, even if they accept and practice Christian concepts and doctrines.

We can arrive at this answer because:

Paradox is the figure of speech that presents two contrary ideas, which cancel each other out as true and coexisting ideas.In “On Being Brought from Africa,” we can see an example of this figure of speech when the speaker forms that black people were forced to adopt Christianity when they were pulled out of Africa and imprisoned in America.However, even though they are Christians and practice Christianity, black people are seen as sinful and pagan people.

In this case, we can see that the paradox in this poem shows that even Christians, blacks are seen as beings turned to sin.

Explanation:

I read this poem for english class. This was one of my questions.

Read the passage from "Marriage Is a Private Affair” by Chinua Achebe. "Have you written to your dad yet?” asked Nene one afternoon as she sat with Nnaemeka in her room at 16 Kasanga Street, Lagos. "No. I’ve been thinking about it. I think it’s better to tell him when I get home on leave!” "But why? Your leave is such a long way off yet—six whole weeks. He should be let into our happiness now.” Nnaemeka was silent for a while, and then began very slowly as if he groped for his words: "I wish I were sure it would be happiness to him.” "Of course it must,” replied Nene, a little surprised. "Why shouldn’t it?” "You have lived in Lagos all your life, and you know very little about people in remote parts of the country.” "That’s what you always say. But I don’t believe anybody will be so unlike other people that they will be unhappy when their sons are engaged to marry.” "Yes. They are most unhappy if the engagement is not arranged by them. In our case it’s worse—you are not even an Ibo.” This was said so seriously and so bluntly that Nene could not find speech immediately. In the cosmopolitan atmosphere of the city it had always seemed to her something of a joke that a person’s tribe could determine whom he married.

Which statement about this passage best explains that the village culture is patriarchal?

Answers

Answer:

third main point:  Love Equals Chocolate

Mixed together, they represent love and chocolate. The brain's connection to the heart may not be entirely physical when it comes to love. In women, chocolate is craved more frequently than in men. For both birthday and Valentine's Day, chocolate is often given to women. In our culture, chocolate is viewed as a gift of romance. You will only find this kind of food outside of the day-to-day, it is for special occasions, and especially appealing to women. In addition, women enjoy chocolate because it conveys love, care, and pampering in a unique way.

Explanation:

This study has shown that those who eat chocolate tend to produce their own natural opiates in their brains, which soothe nerves and make them feel good. After muting the receptors that detect opioids, the chocolate cravings diminished.

When I finally saw her, I stood there stunned by her beauty. After a moment I fell to one knee and held the ring out to her. I did not even get the words our before she cried out, ‘Yes! I will marry you.’” “Emily sat up in her room feeling lonely. She had no idea Louis was outside. He ran up the steps, and threw the door open. He raced around the house to find Emily. They were stunned when they finally saw each other. After a moment of awkward silence, he fell to one knee and held the ring out to her. Before Louis could say a word, Emily cried out, ‘Yes! I will marry you.’ And hugged him.” What is the main difference between these two interpretations? A. Setting B. Point of View C. The author's tone D. The type of literature the story is presented.

B. Point of View

Explanation: The main difference in the two paragraphs is the point of view. The first paragraph is shown through the POV of the man (Louis) and the second paragraph shows the POV of Emma.

The setting of the story is the same so that cannot be the answer. The type of literature the story is presented is also the same. I see no major difference in the passages except for the change in POV.
