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.

great love and great achievement involve great risk ​

Answers

Answer:

It is a quote by the Dali Lama.

Explanation:

It means you get what you pay for, and accomplishments do not always come effortlessly. If you want something bad enough then you should work hard and try to make it happen, even if there is a chance that it might not go the way that you thought it would.

It is a Dalai Lama quotation. It implies that you get what you pay for and that success is not always effortless. Even though there's a chance it won't turn out the way you expected it to, if you really want something bad enough, you should put in the effort to make it happen.

What is great achievement?

A great accomplishment is anything that was accomplished with a lot of talent or effort. Achieve and attainment frequently connote the accomplishment of a significant or challenging task—a lofty goal or a magnificent effort. High school graduation is a success.

As synonyms for achievement, the words exploit and feat are frequently used. Achievement denotes hard-won triumph in the face of adversity or opposition, even if all three terms mean "a notable deed": a proud sense of having accomplished something tough and good. He had a genuine sense of accomplishment after fixing the car by himself.

Thus, It is a Dalai Lama quotation.
