The Black Death A The growing cities of the Middle Ages could be exciting places. However, many were dark, unsafe, and unhealthy. Streets were narrow, crooked, and filthy. There were no streetlights or police. Many people did not go out alone at night for fear of robbers. If people did go out, they often took servants along with them for protection and to carry lanterns or torches to light the way. Waste was dumped into open gutters. All in all, conditions were disgusting. This caused diseases to spread quickly through the crowded cities. B Beginning in 1347, one such disease, a terrible plague, swept through Europe. The disease was called the Black Death because of the darkened color of its victims’ faces after they died. The plague began in Asia and spread along busy trade routes. Trading ships carried the disease west to the Mediterranean. From the Mediterranean ports, the disease spread throughout most of Europe. Rats on the ships carried the disease. Fleas from the rats spread the disease to people. C Once people became infected, the disease could be spread from person to person. People became infected as they came in contact with the sick. According to Jean de Venette, a friar who lived at the time, young people were more likely to die than old people. Those who got sick lasted only two or three days and then died suddenly. This happened in such great numbers that often those who lived could not keep up with burying the dead. The friar wrote, “Someone who was healthy one day could be dead and buried the next. . . . A healthy person who visited the sick hardly ever escaped death.” D No one knows the exact number of plague deaths in Europe. Some guess that about 25 million people died in Europe from 1347 to 1351. This was about one third of the entire population. The death rate varied from place to place. Towns seemed to be harder hit than the countryside. Some entire villages and towns were wiped out. The plague affected the rich as well as the poor. Even the great and powerful, including royalty, were struck down. Throughout Europe, populations were devastated by, as the Welsh called it, “death coming into our midst like black smoke.” E The Black Death greatly affected Europe. Relations between the upper classes and lower classes changed. Workers, now in short supply, demanded higher wages. In several European countries, peasants staged uprisings. There were emotional effects as well. In some areas, the theme of death appeared in poetry, sculpture, and painting. People’s faith was shaken. The church lost some of its power and importance. The Black Death took a greater toll on human life than any war or illness before that time. It was perhaps the greatest tragedy in all of European history. What is the main purpose of this article? a. To inform people of precautions to take against the plague c. To talk about cures for the plague b. To inform people about a historically important plague d. To tell how friars dealt with the plague.

The paragraph that best develops the man vs. society conflict Marcus faces in the novel little brother is "Don't you say a word about him," I said, the anger bubbling over. "You're not fit to talk about him. Yeah, I understand that everything's different now. We used to be a free country. Now we're not."

The character of Marcus deals with several conflicts through the story, one of them being the man vs society.

What is the man vs. society conflict?

The man vs society issue arises when the protagonist decides to act on a strong conviction that contrasts with the bulk of the society or surrounds. This kind of conflict is categorized as an external threat because it involves a character and outside group.

One of the most prevalent themes in literature is a protagonist's rebel against expectations from their family, society, the government, etc.

However, the man vs society conflict here is that when one or more individuals rebel against the behavioral norms or codified systems of their society.

What is the novel little brother?

Cory Doctorow's book Little Brother is available from Tor Books. It was released on April 29, 2008.

In the wake of a terrorist attack on the San Francisco-Oakland Bay Bridge and the BART system, four teens in San Francisco must defend themselves against the Department of Homeland Security's assaults on the Bill of Rights.

Little Brother's intention to present obscene notions to a younger crowd is not hidden.

(1) Year-round schooling would help student achievement. (2) Not so much information would have to be crammed into nine months. (3) Furthermore, the elimination of long breaks, particularly summer break, would significantly reduce "learning loss” and the additional time wasted at the beginning of each academic year to reteach previously learned material. (4) It is clear that year-round schooling helps students learn and retain more. (5) The United States is not the only country to experiment with a year-round school schedule. (6) Although many still claim that evidence about year-round school and its link to higher achievement is inconclusive, these people need to open their eyes and see that students in these schools consistently score higher on certain assessments than students who attend schools with traditional nine-month calendars. (7) It is about time that we replaced our outdated and inefficient school calendars.

A bitter soul dominated the various curved and angular surfaces known by a careless world as the face of Penrod Schoneld. Except in solitude,
that face was almost always cryptic and emotionless; for Penrod had come into his twelfth year wearing an expression carefully trained to be
Inscrutable. Since the world was sure to misunderstand everything, mere defensive instinct prompted him to give it as little as possible to lay
hold upon. Nothing is more impenetrable than the face of a boy who has learned this, and Penrod was habitually as fathomless as the depth of
his hatred this morning for the literary activities of Mrs. Lora Rewbush-an almost universally respected fellow citizen, a lady of charitable and
poetic inclinations, and one of his own mother's most intimate friends.
Mrs. Laura Rewbush had written something which she called "The Children's Pageant of the Table Round, and it was to be performed in public
that very afternoon at the Women's Arts and Guild Hall. And if any flavor of sweetness remained in the nature of Penrod Schofield after the

What does the three encounters between Galaad and Mrs. Whitaker reveal about their relationship? (Use evidence from the text.)

Answers

Answer:

The three encounters between Sir Galaad and Mrs. Whitaker reveals that Sir Galaad treated her like a queen but Mrs. Whitaker wants to be treated normally.

Explanation:

'Chivalry' is a short story written by Neil Gaiman. The story is about an elderly woman Mrs. Whitaker, who finds the Holy Grail in an old shop.

In the story, Mrs. Whitaker was visited by Sir Galaad, Knight of the Round Table. In the three encounters between Sir Galaad and Mrs. Whitaker, Sir Galaad treats Mrs. Whitaker as a queen by offering her various precious gifts in exchange of the Holy Grail. Instead, Mrs. Whitaker wants to be treated normally.

Though, their meeting was a magical one, Sir Galaad, Knight of the Round Table, was here visiting and having teatime with Mrs. Whitaker. Despite, having magical elements the author has portrayed their relationship as somewhat a normal interaction between common people.

Textual evidence:

'When she got home, Galaad was waiting for her. He was giving the neighborhood children rides on Grizzel’s back, up and down the street.

“I’m glad you’re here,” she said. “I’ve got some cases that need moving.”

She showed him up to the boxroom in the top of the house. He moved all the old suitcases for her, so she could get to the cupboard at the back.'

Scientists mixed local bees with African ones to create a bee that would make more honey. They ended up with something much different. The new bees evolved in unexpected ways. They multiplied and migrated north. These Africanized honeybees are now known as killer bees for several scary but legitimate reasons.Killer bees are far more aggressive than their relatives. They have been known to attack in great numbers, even when there has been no direct threat on their hives. They have swarmed because of loud noises, dark clothing, bright jewelry, and even strong perfume. They will chase a person for more than a quarter of a mile and remain angered for up to 24 hours.Killer bees are also dangerous because of their sting. While most bees take up to 30 seconds to attack, killer bees sting in just 3 seconds. Their venom is no stronger than a regular bee's, but when one killer bee stings, others follow. With up to 80,000 members in a colony, victims are quickly overwhelmed. So many stings in such a short time can cause allergic reactions. Victims enter a state of shock, lose blood pressure, and in many cases, die.A final reason why "killer" has been added to their name is the unfortunate number of deaths they have caused. Experts estimate that the Africanized honeybee moves at a rate of about 200 miles each year. As the bees claim new territory, they claim new victims as well. More than 1000 people have been stung to death in South and Central America. There have been rising numbers of attacks in Mexico and a handful in the United States. Once a swarm sets sights on a victim, it is very difficult for the victim to escape. Once attacked, it is very difficult to survive.Thankfully, there has been no killer bee invasion as some once predicted. Although there is no need for panic, the threat of the killer bee is real and should be taken seriously. It is good practice to call a professional to remove beehives in your area. If you are stung multiple times by any insect, you should always seek medical attention. You may not be expert enough to tell the difference between a killer bee and a less dangerous one, so be smart. It is better to be safe than sorry.Which details relate to the main fact in the third paragraph? (5 points)Group of answer choicesKiller bees attack in great numbers. They swarm for many reasons.
