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.

Answer the following question based on the Compton's Encyclopedia reading:

Which choice best describes the reasons behind Jonas Salk's decision to search for a cure for poliomyelitis?

The disease affected children in the United States all of Salk's life.
The disease became an epidemic shortly after Salk became a doctor.
Jonas Salk's own child contracted poliomyelitis as an infant.
Jonas Salk suffered from poliomyelitis as a young child.

Answers

Answer 1

Answer:

There really is no answer. A is a 1/2 truth. B the reasons for not choosing B are given. We know nothing about C or D, but they are likely not true. None of his 3 children had Polio. No mention is made of himself.

I guess B, but a marker could pick anything, the choices are so bad.

Explanation:

A isn't true. He lived long after the vaccine was developed.

B. It was a dreaded disease long before he became a doctor. and some 15 years after. (1939 to 1954)

C. We don't know anything about Salk's personal life. C and D are both not part of the same missing piece of information.

D. We don't know if he did or not. The article does not say.

If a reader were to examine the vocabulary used in the novel, he
or she would be analyzing what?

Answers

Answer:

The answer is that the reader would be analyzing the diction of a novel.

Explanation:

Diction refers to the linguistic choices a writer makes to effectively convey an idea, a point of view, or tell a story. The utilization of diction is the careful selection of words to communicate a message or establish a particular voice or writing style. For example, flowy, figurative language creates colorful prose, while a more formal vocabulary with concise and direct language can help a main point to come across as clear and precise.    

Writers use diction in order to choose specific words and phrases depending on the outcome they’re trying to achieve. Diction can:  

Create a certain tone that supports purpose. The purpose of a piece of writing determines its diction. In literature and fiction writing, writers often use informal diction and figures of speech—words used for non-literal meanings, like similes and metaphors. If a scientist is publishing a paper on their research, however, the language will be technical, concise, and formal, written for a specific audience. Support the setting. In fiction writing, the language an author uses supports the basic story elements, like setting. Diction helps establish when and where a story is set by using language native to that time and place, which is called colloquial diction. For example, a story set in New York City will have a different style of language compared to a story that takes place in London. Establish a narrative voice and tone. A writer’s attitude towards the subject of a story comes through in the words used throughout the story. This helps establish tone and impacts a reader's emotional response. For instance, the tone of a horror novel will be very different to that of a romance novel. Bring characters to life. A writer can tell a reader a lot about characters through their dialogue. The way a character uses diction reflects personal details like age and gender, background, social setting, and profession.

An action in a sentence can be represented in two ways, namely active and passive voice.

The passive voice always uses the past participle form of the main verb irrespective of any tense. Only the auxiliary verbs depend upon the sentence given in active voice.

The correct answer is D)My radio has not been repaired.

Option D is correct as the given sentence is in active voice and to transform it into passive voice the subject of the given sentence

(The mechanic) come in the place of the object and vice versa. Also, as the sentence is in the present perfect tense, 'been' is added.

Imagine you are writing an argument to convince others that soda machines should be removed from all public buildings, including schools. Which group of people would you likely have to work most to convince?

Parents
Doctors
Students
Teachers

Answers

It would be both the parents and the doctors. The schools are the ones who had the machines installed in the first place and the students are the ones who take the most kick out of it.

Doctors, as we know, are experts in health and living conditions, which means that they know it’s a health risk for those who tend to consume sodas more often then they should.

Parents only want the best for their children and soda/pop are considered bad for the digestive system if consumed in massive amounts. Because parents don’t have complete control on their children at school, the freedom of course the child has gets exploited.

Three rounds of artificial insemination with her husband's sperm have failed. There is no evidence of any problem with her husband's sperm count or motility. What would be the most likely next step?

a. Another round of artificial insemination with the husband's sperm
b. Artificial insemination is donor sperm
c. In vitro fertilization using the wife's egg in donor sperm
d. In vitro fertilization using a donor egg and her husband's sperm

Answers

Answer:

Hence the correct answer is a. Another round of artificial insemination with the husband's sperm.

Explanation:

Here the correct option is Another round of artificial insemination with the husband's sperm.

Because the couple wants their own biological child, So that, they can't use donor's eggs or sperm. Thus the options B, C, and are not correct.

The next step that should be taken is D. In vitro fertilization using a donor egg and her husband's sperm.

Based on the information given, three rounds of artificial insemination with her husband's sperm have failed, therefore, it shouldn't be tried anymore.

The best option will be in vitro fertilization using a donor egg and her husband's sperm. In vitro fertilization simply means the process of fertilization where an egg will be combined with sperm in vitro.

Read the excerpt from President John F. Kennedy’s inaugural address. Which statement best describes the main message of the passage?

In your hands, my fellow citizens, more than in mine, will rest the final success or failure of our course. Since this country was founded, each generation of Americans has been summoned to give testimony to its national loyalty. The graves of young Americans who answered the call to service surround the globe.

Now the trumpet summons us again—not as a call to bear arms, though arms we need—not as a call to battle, though embattled we are—but a call to bear the burden of a long twilight struggle, year in and year out, "rejoicing in hope, patient in tribulation"—a struggle against the common enemies of man: tyranny, poverty, disease and war itself.

And so, my fellow Americans: ask not what your country can do for you—ask what you can do for your country.

My fellow citizens of the world: ask not what America will do for you, but what together we can do for the freedom of man.

A. War is the only way to solve the problems of the world.

B. People should work together to better their society.

C. Americans are incredibly loyal to their country.

D. The US government should help those in need.
