Read the entry on Jonas Salk from Compton's Encyclopedia/The Britannica School Edition, and answer the question beneath the text. Compton's Encyclopedia Jonas Salk (1914-1995). For the first half of the 20th century, poliomyelitis, also known as infantile paralysis, was one of the most dreaded diseases to attack young people. By 1955 American physician and researcher Jonas Salk had developed a vaccine that almost eradicated the disease in the United States and other developed countries. Jonas Edward Salk was born in New York City on October 28, 1914. He graduated from the City College of New York in 1934 and earned his doctorate in medicine from New York University's College of Medicine in 1939. While in medical school he had worked with Thomas Francis Jr. on killed-virus immunology studies. In 1942 he joined a group at the University of Michigan working on a vaccine against influenza. The vaccine was perfected in 1953. In 1947 Salk became associate professor of bacteriology and head of the Virus Research Laboratory at the University of Pittsburgh School of Medicine. There he began working on the polio vaccine. Three viruses caused polio, and a vaccine had to be effective against all of them. By 1952 Salk had developed such a vaccine and conducted field tests on children. His findings were published in 1953, and a mass field test was done the next year. On April 12, 1955, the vaccine was released for use in the United States. In 1957 Salk was named professor of experimental medicine at Pittsburgh, and in 1963 he went to San Diego as head of the Institute (later named the Salk Institute) for Biological Studies. In 1977 Salk was awarded the Presidential Medal of Freedom. He died on June 23, 1995, in La Jolla, California.

Answers

Memorize the presentation word for word. Option D

It is not advisable to commit the presentation word for word to memory while reading a report after drafting a written copy. Although familiarity with the material is essential, rigid memorization may impede adaptability and natural delivery.

Rather, a more interesting and successful presentation is encouraged by comprehending the subject matter, concentrating on the important aspects, and allowing for flexibility. Hence the answer is option D

Mystery family was quite unusual. They belong to a prominent group in Emporia. Imperial Clan. Just mention the name given to someone in Emporia shivers. There were eight groups in Ampioria. The leader of the dynasty was the leader of the Mercy family, of course, the leader of the John Mercy dynasty.


John Mercy was a beautiful wife named Sir Mercy. Sarah Mercy was from the Golden Clan. Golden Clan was in charge of the palace. It was clear and it sure was always safe.


There was a big problem. The cruel family had no children, nor even a daughter. This was a big problem, because if they did not have a child, they would not be heir to the throne. Morsi family always ruled the umpire from the Sun's revolution. If they die without the heirs, then it could throw all the groups in another revolution.


There was a solution. The solution was to talk about The Witch living in the suburbs of Emporia. Someone wanted to crazy mad. He was the most powerful person in Emporia. Even the groups did not meet. Just one day when Witch Magic would accept a question from every tribe on the holy day, it was the holiest day in the Emporia on 1st July, when power and strength increased twice. On July 1st, the day when the monsters are the most powerful.


John Witch went. As a tradition, he hit Witch's door three times.


"Who is it?" Dr.


"It's me, John Marcy, the leader of Imperial Clan," John said. "O great witch, I have heard your wisdom."


"Well, come in." The Witch said "John Mercy of Imperial Clan in response to your question."


John is not a successor to explain his problem.


"Solution is easy." Dana said.


"I will give you a son. He is stronger than you, you must be stronger than you."


"Thank you, Great One" John said.

John left with a smile on his face.


Witch shook the hidden dead witch and said, if you know, what would happen.

"Empia will soon belong to me." Dr.


La famille de mystère était assez inhabituelle. Ils appartiennent à un groupe important dans les Emporia. Clan Impérial. Il suffit de mentionner le nom donné à quelqu'un dans Emporia frissons. Il y avait huit groupes à Ampioria. Le chef de la dynastie était le chef de la famille Mercy, bien sûr, le chef de la dynastie John Mercy.

  John Mercy était une belle femme nommée Sir Mercy. Sarah Mercy était du Golden Clan. Golden Clan était en charge du palais. C'était clair et c'était toujours sûr.

  Il y avait un gros problème. La famille cruelle n'avait pas d'enfants, ni même une fille. C'était un gros problème, car s'ils n'avaient pas d'enfant, ils ne seraient pas héritiers du trône. La famille Morsi a toujours dirigé l'arbitre depuis la révolution du Soleil. S'ils meurent sans héritiers, tous les groupes pourraient alors se lancer dans une autre révolution.

  Il y avait une solution. La solution consistait à parler de The Witch vivant dans la banlieue d’Emporia. Quelqu'un voulait devenir fou fou. Il était la personne la plus puissante d'Emporia. Même les groupes ne se sont pas rencontrés. Un jour seulement où Witch Magic acceptait une question de chaque tribu le jour sacré, c’était le jour le plus sacré de l’Emporia le 1er juillet, lorsque le pouvoir et la force ont été multipliés par deux. Le 1er juillet, jour où les monstres sont les plus puissants.

The part where a comma splice or fused sentence occurs is in "dogs as."

In this sentence, there's a comma splice because it joins two independent clauses ("dogs as a result" and "Derek had to settle...") with just a comma, which is incorrect punctuation.

A comma splice typically happens when two independent clauses are joined by a comma without a coordinating conjunction (such as "and," "but," "or," etc.) or without proper punctuation like a semicolon or period.

To fix this issue, you could replace the comma with a semicolon or add a coordinating conjunction after the comma, like "dogs as a result, but Derek had to settle..." This would make the sentence grammatically correct.

Read the two passages from Sugar Changed the World. By the late 1700s, Saint Domingue (what is now Haiti) was the world center of sugar. So many sugar plantations dotted the landscape that slaves called commanders managed other slaves. On the night of August 14, 1791, commanders from the richest sugar plantations in Saint Domingue gathered in a place called Alligator Woods and swore a solemn oath. They would rise up against their white owners, "and listen to the voice of liberty which speaks in the hearts of all of us." That voice told them to destroy everything related to sugar. Sugar made the Africans slaves, so sugar must be wiped off the island, now a vast sugar factory to the world. By the end of August, the French colony was in flames. So many cane fields were on fire that the air was filled with "a rain of fire composed of burning bits of cane-straw which whirled like thick snow." Smashing mills, destroying warehouses, setting fields on fire, the freedom fighters demolished some one thousand plantations—and that was just in the first two months of their revolution. The fight against sugar and chains soon had a leader, Toussaint, who called himself "L’Ouverture”—the opening. Toussaint was making a space, an opening, for people to be free. When the Haitians defeated the French armies, Napoleon lost control of the world's most productive sugar islands and with it his dream of great sugar profits. As a result, Napoleon had no use for the land in North America he had so recently obtained from Spain. Napoleon did, though, need money to pay for his wars. That is why he sold the vast Louisiana Territory to Jefferson for the bargain price of just fifteen million dollars. What textbooks call the Louisiana Purchase should really be named the Sugar Purchase. Americans obtained the middle part of what would become their nation because the Haitians achieved their freedom. Which claim do both passages support? Haiti is a small island nation that has had little effect on events in North America or Europe. Sugar was such a powerful economic force that it led to significant political changes. Events in one part of the world rarely have a significant effect on people in other regions. Natural disasters such as fires can have both political and economic impacts on colonies.

Answers

The claim that is supported by both passages is that "sugar was such a powerful economic force that it led to significant political changes".

From the excerpts, it was stated that Africans played a pivotal role in the sugar plantations as they worked on it. Later, the commanders gathered in order to stop the unfair treatment that they were going through.

This led to the burning of many sugar plantations and this was pivotal in making significant political changes.

Some of the political changes include the fact that Haitians defeated the French armies, and Napoleon lost control of the world's most productive sugar islands.

In conclusion, the correct option is B.

Describe the spirits of the dead. What role do they have in the lives of the living in particular religions? How are the beliefs about the dead reflected in religious practice?

Answers

In the religions of Africa, life does not end with death, but continues in another realm. The concepts of "life" and "death" are not mutually exclusive concepts, and there are no clear dividing lines between them. Human existence is a dynamic process involving the increase or decrease of "power" or "life force," of "living" and "dying," and there are different levels of life and death. Many African languages express the fact that things are not going well, such as when there is sickness, in the words "we are living a little," meaning that the level of life is very low. The African religions scholar Placide Tempels describes every misfortune that Africans encounter as "a diminution of vital force." Illness and death result from some outside agent, a person, thing, or circumstance that weakens people because the agent contains a greater life force. Death does not alter or end the life or the personality of an individual, but only causes a change in its conditions. This is expressed in the concept of "ancestors," people who have died but who continue to "live" in the community and communicate with their families.

This entry traces those ideas that are, or have been, approximately similar across sub-Saharan Africa. The concepts described within in many cases have been altered in the twentieth century through the widespread influence of Christianity or Islam, and some of the customs relating to burials are disappearing. Nevertheless, many religious concepts and practices continue to persist.

Arrange the Gospel themes in New Testament order.
1.The Humble Servant
2.The Son of God
3.The Kingly Messiah
4.The Son of Man

Answers

The order is as follows:


First. 3. The Kingly Messiah

Second. 1. The Humble Servant

Third. 4. The Son of Man

Fourth. 2. The Son of God


This is the order in which each theme takes place in New Testament. So let me explain step by step:


First.

3. The Kingly Messiah


According to New Testament, at this point Jesus came to the world. He's known as the Messiah and according to the bible He was born in Bethlehem, the city of David to be the Savior of the world as the Old Testament did establish. So according to New Testament He took the very nature of a servant,  being made in human likeness.  So as a man He humbled himself


Second.

1. The Humble Servant


According to New Testament this happened as Jesus and his disciples approached Jerusalem. So they came to the towns of Bethphage and Bethany on the Mount of Olives. So Jesus entered Jerusalem sat on a donkey as The Humble Servant. The young donkey belonged to a man. The disciples borrowed it for this purpose.


Third.

4. The Son of Man


Jesus stated that He was The Son of Man suggesting that He was born from María who was married to Joseph. So He declared several times that  the Son of Man did not come to be served, but to serve, and to give His life a ransom for many. So this was an important statement of this man.


Fourth.

2. The Son of God


Jesus stated that He was The Son of God as well suggesting that He came from the heaven sent by God the Father. In this way, He stated that his father was always at his work, and He too was working calling God his own Father. Also, He declared that whatever the Father did the Son also did.
