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.

Which detail best develops the character of the narrator, Jane Eyre, in the excerpt?
excerpt from Jane Eyre
by Charlotte Brontë
In the following excerpt, the narrator, Jane Eyre, describes an interaction with her nursemaid, Bessie.
Bessie asked if I would have a book: the word book acted as a transient stimulus, and I begged her to fetch Gulliver's Travels from the library.
This book I had again and again perused with delight. I considered it a narrative of facts, and discovered in it a vein of interest deeper than what
I found in fairy tales: for as to the elves, having sought them in vain among foxglove leaves and bells, under mushrooms and beneath the
ground-ivy mantling old wall-nooks, I had at length made up my mind to the sad truth, that they were all gone out of England to some savage
country where the woods were wilder and thicker, and the population more scant; whereas, Lilliput and Brobdignag being, in my creed, solid
parts of the earth's surface, I doubted not that I might one day, by taking a long voyage, see with my own eyes the little fields, houses, and trees,
the diminutive people, the tiny cows, sheep, and birds of the one realm; and the corn-fields forest-high, the mighty mastiffs, the monster cats,
the tower-like men and women, of the other. Yet, when this cherished volume was now placed in my hand-when I turned over its leaves, and
sought in its marvellous pictures the charm I had, till now, never failed to find-all was eerie and dreary; the giants were gaunt goblins, the
pigmies malevolent and fearful imps, Gulliver a most desolate wanderer in most dread and dangerous regions. I closed the book, which I dared
no longer peruse, and put it on the table, beside the untasted tart.
Bessie had now finished dusting and tidying the room, and having washed her hands, she opened a certain little drawer, full of splendid shreds
of silk and satin, and began making a new bonnet for Georgiana's doll. Meantime she sang: her song was-
"In the days when we went gipsying,
A long time ago."
I had often heard the song before, and always with lively delight; for Bessie had a sweet voice. --at least, I thought so. But now, though her voice
was still sweet, I found in its melody an indescribable sadness. Sometimes preoccuniad with

Which sentence contains evidence for the main idea of the passage?
Junk food ads cause people to eat more junk food. Research shows that some junk food ads target kids. A study from the Public Library of Science showed that ads aimed at kids focused more on the toys that come with junk food than on the food itself. Some fast-food restaurants also make ads connected to TV shows and movies that are popular with children. Ads like these create a demand for junk food among kids. And those kids are likely to continue to eat the same unhealthy foods when they become adults. We can only expect these kinds of ads to stop if governments create strict laws to end them.

This poem also refers to another text in the Bible. Look up the text and explain what the poet means.

I have a cottage by the sea. It's night.
I hear on end, hitting the waves on end
against the rock my cottage stands on
with all the ocean's hectic power.
I hear the winds crying — a whimper, a complaint,
as of lost souls in their need
all roving, lyent, living in grave and death
find no rest, but still seek and yearn.


My fire burns, my cherry gives its light.
I hear how the storm is raging out there,
I hear the winds snatching at my lozenges;
inside it is safe, warm and dense.


Come night, come again and wind, come ocean —
it's a rock my cottage stands on!

Which sentence in the excerpt best supports the theme of harmonious living?
A Spark Neglected Burns the House
by Leo Tolstoy (adapted excerpt)
There once lived in a village a peasant named Iván Stcherbakóf. He was comfortably off, in the prime of life, the best worker in the village, and
had three sons all able to work. The eldest was married, the second about to marry, and the third was a big lad who could mind the horses and
was already beginning to plough. Iván's wife was an able and thrifty woman, and they were fortunate in having a quiet, hard-working daughter-
in-law. There was nothing to prevent Iván and his family from living happily. They had only one idle mouth to feed; that was Iván's old father,
who suffered from asthma and had been lying ill for seven years. Iván had all he needed three horses and a colt, a cow with a calf, and fifteen
sheep. The women made all the clothing for the family, besides helping in the fields, and the men tilled the land. They always had grain enough
of their own to last over beyond the next harvest and sold enough oats to pay the taxes and meet their other needs. So Iván and his children
might have lived quite comfortably had it not been for a feud between him and his next-door neighbor, Limping Gabriel, the son of Gordéy
Ivánof.
As long as old Gordéy was alive and Iván's father was still able to manage the household, the peasants lived as neighbors should. If the women
of either house happened to want a sieve or a tub, or the men required a sack, or if a cart-wheel got broken and could not be mended at once,
they used to send to the other house, and helped each other in neighborly fashion. When a calf strayed into the neighbor's thrashing-ground,
they would just drive it out, and only say, "Don't let it get in again, our grain is lying there." And such things as locking up the barns and
outhouses, hiding things from one another, or backbiting were never thought of in those days.
That was in the fathers' time. When the sons came to be at the head of the families, everything changed.
