what does the writer wanted to mean in the story The Portrait of a Lady​

Answers

The story portrays a grandson's perception of his grandmother and how their bond of love undergoes changes. Moral: The story puts light on the need of companionship and friendship felt by our elders. It also shows how love and emotion is experienced not only by human beings but animals and birds too.

Explanation:

The Portrait of a Lady is the story of a spirited young American woman, Isabel Archer, who, "confronting her destiny",finds it overwhelming. She inherits a large amount of money and subsequently becomes the victim of Machiavellian scheming by two American expatriates. Like many of James's novels, it is set in Europe, mostly England and Italy. Generally regarded as the masterpiece of James's early period, this novel reflects James's continuing interest in the differences between the New World and the Old, often to the detriment of the former. It also treats in a profound way the themes of personal freedom, responsibility, and betrayal.

Analysis essay on Romeo and Juliet

Answers

Answer:

When Ernenek woke up to lift his head from the fur sack, his first thought was usually for the pile of meat put to rot near the lamp to make it tender and tasty. But not that day. That day, seeing Siksik in a corner of the little igloo, ready to wash her husband's clothes, she made a sudden decision before satisfying the demands of her stomach: since she was contributing more than her duty to the maintenance of the tiny community. He might as well claim to participate in Anarvik's marital rights as well, without having to ask her permission every time he needed Siksik's services. Ernenek ... see more ...

Over it he put on a heavy bearskin tunic, hair pulled out, and tucked the ends of the leggings into a pair of sealskin ankle boots. Bent over, because the ice dome was too low for him, with the circular knife he cut thick slices from the heap of over-seasoned, rubbed meat and filled his mouth with the palm of his hand. He crawled through the narrow tunnel of snow, propping himself up on his elbows and knees, and dragging the sled-headed dog behind him by the ears, out of the igloo. The rest of the team followed, brushing the frost from their thick hair, barking with hunger, and bared their teeth, flattened with stone so that they would not devour the harness of the sled; with more wolves than dogs, they had sharp snouts and gleaming yellow eyes. Ernenek made sure that everyone wore the sandals that should protect their legs from the bite of ice and sea salt. Then he hooked them to the sled, climbed onto it, removed the anchor buried in a heap of ice, and waved the whip

Explanation:

Read the passage from Sugar Changed the World. Sugar was the connection, the tie, between slavery and freedom. In order to create sugar, Europeans and colonists in the Americas destroyed Africans, turned them into objects. Just at that very same moment, Europeans—at home and across the Atlantic—decided that they could no longer stand being objects themselves. They each needed to vote, to speak out, to challenge the rules of crowned kings and royal princes. How could that be? Why did people keep speaking of equality while profiting from slaves? In fact, the global hunger for slave-grown sugar led directly to the end of slavery. Following the strand of sugar and slavery leads directly into the tumult of the Age of Revolutions. For in North America, then England, France, Haiti, and once again North America, the Age of Sugar brought about the great, final clash between freedom and slavery. Which sentence best states the authors' claim in this passage? Economic demand for sugar led to political pressure to end enslavement. The growing demand for sugar made the lives of enslaved people even worse. Turning Africans into objects was important for the sugar industry to succeed. Monarchies became increasingly strong and popular during the Age of Sugar.

Answers

Answer:

A). Economic demand for sugar led to political pressure to end enslavement.

Explanation:

The first statement i.e. 'economic....enslavement' most aptly states the author's claim in the given passage as he says that 'they could no longer stand being objects themselves.' The author provides sufficient support to justify his claim by stating that 'the global hunger for slave-grown sugar led directly to the end of slavery.' The increasing economic demand for sugar eventually led to 'the Age of Revolutions and a clash between sugar and slavery' as the slaves were a crucial factor in the production of the sugar and meet the rising demands. Thus, this led to the end of slavery, and hence, option A is the correct answer.

Answer:

A). Economic demand for sugar led to political pressure to end enslavement.

2. Millions of plastic water bottles end up in the ocean each year, adding to the millions already there and not decomposing.
3. Recycling has become easier with many public places including recycling bins right next to all garbage cans.
4. Plastic that hasn’t been recycled has extremely harmful effects to the wildlife that live in the ocean.

Answers

Answer:

1. Litter is not only ugly, but also harmful to animals in national parks

Explanation:

When writing an essay in support of a point, you have to select salient points that are consistent and relatable to what you're writing about..

Younique is writing an essay in support of recycling to reduce garbage in the ocean and therefore she has to bring points that relates to side effects of throwing garbage in the ocean, how easy it is to recycle garbage and other necessary points.

The truly odd one out is option A which says "Litter is not only ugly, but also harmful to animals in national parks".

This has no direct connection to effect of garbage in the ocean or recycling so this is the piece of evidence with the least relevance to her argument.

He was supposed to have a baseball game, and the coach was going to put Fredrick in as the pitcher, but it was cancelled because of rain. Instead, Fredrick pulled out his baseball cards, hoping the familiar faces of the famous players would cheer him. First, Fredrick sorted the cards by team, then by the year the card was printed. He examined each one before carefully putting it back into its plastic cover and filing it away. When he finished, the rain had stopped, and he realized that he felt better. 19. Fredrick _______ organized his cards. Group of answer choices relentlessly incorrectly alphabetically methodically

Answers

Answer:

Fredrick methodically organized his cards.

Explanation:

Relentlessly refers to doing something in an intense or harsh way. It could be an option, but there is not much in the passage to say Fredrick organized the cards relentlessly. His action is not described in any way that makes it seem harsh or intense.

Incorrectly refers to doing something the wrong way. There is no indication that Fredrick misplaced a card or did anything wrong while sorting them. This is not an option as well.

Alphabetically would mean he used the way the letters are ordered in the alphabet to organize the cards. However, we know he did not. Fredrick organized them by team and year. This is also not an option.

Finally, methodically refers to doing something systematically, in an orderly manner. As we can see, Fredrick did have a method to organize the cards. He sorted them according to certain standards. Therefore, this is the correct option to fill in the blank.

****PLATO WORK PLZ HELP 30 POINTS**** Evaluate the end of the story when D introduces an element of dramatic irony. Why do you think the narration switches focus to the gun after the characters leave the ruined city? As the gun parts drive toward the broken gun, what mood is created for the reader? How is this ending an example of dramatic irony?

Answers

Answer:

The ending of the story allows the events to remain open-ended. The crew leaves the planet hoping to come back, believing that the gun has been destroyed. Only the reader knows that a small army of self-repairing gadgets and an atomic warhead are moving toward the gun. Dramatic irony occurs when the reader has more knowledge about a particular outcome than the characters. So, in “The Gun,” the reader knows that the gun will repair itself, but the characters flying away are unaware of this information. This ending evokes a mood of fear and suspense as the reader realizes that the weapon of destruction will regenerate itself and will most likely strike the crew and others once they return to the planet.

Explanation:

Answer:

When Philip K. introduces the element of dramatic irony, it leaves the feeling of discontent. There wasn't a happy ending to this story because we know what might happen next. They wasn't exactly an ending because we know that there is self-repairing gadgets. The crew thought the gun was destroyed. The narration switches focus to the gun to inform the reader and not the characters. This evokes fear and uneasiness in the reader. The destructive weapon will soon regenerate itself, and will attack the crew when they return.

Explanation:

This is the only sentence that compares two elements. All of them contrast them. We know this because it uses the word 'same.'

This red snapper is delicious. It is seasoned with the same spices as the river trout I'm also enjoying. This statement compares two elements. Hence option C is correct.

What is Statement ?

A statement differs from a sentence in the latter situation because a sentence is simply one formulation of a statement, whereas there may be many additional formulations conveying the same statement.

By a statement, I mean "that which one states," not "that which one states." There are several meanings of the term statement, but it commonly refers to a coherent declarative utterance that is either true or untrue (bivalence). A proposition is a statement made by (or the meaning of) a true or false declarative phrase. A proposition is what a statement signifies; it is the thought or idea expressed by a statement, i.e., what it represents. "2 + 2 = 4" might be said.
