What is an Insect? When we remember that the insects alone comprise four-fifths of the animal kingdom, and that there are upwards of 200,000 living species, it would seem a hopeless task to define what an insect is. But a common plan pervades the structure of them all. The bodies of all insects consist of a succession of rings, or segments, more or less hardened by the deposition of a chemical substance called chitine; these rings are arranged in three groups: the head, the thorax, or middle body, and the abdomen or hind body. In the six-footed insects, such as the bee, moth, beetle or dragon fly, four of these rings unite early in embryonic life to form the head; the thorax consists of three, as may be readily seen on slight examination, and the abdomen is composed either of ten or eleven rings. The body, then, seems divided or insected into three regions, whence the name insect.

Science tells us that all objects are made visible to us by means of light; and that white light, by which we see things in what may be called their normal aspect, is composed of all the colors of the solar spectrum, as may be seen in a rainbow; a phenomenon caused, as everybody knows, by the sun's rays being split up into their component parts.

This light travels in straight lines and, striking objects before us, is reflected in all directions. Some of these rays passing through a point situated behind the lenses of the eye, strike the retina. The multiplication of these rays on the retina produces a picture of whatever is before the eye, such as can be seen on the ground glass at the back of a photographer's camera, or on the table of a camera obscura, both of which instruments are constructed roughly on the same principle as the human eye.

These rays of light when reflected from an object, and again when passing through the atmosphere, undergo certain modifications. Should the object be a red one, the yellow, green, and blue rays, all, in fact, except the red rays, are absorbed by the object, while the red is allowed to escape. These red rays striking the retina produce certain effects which convey to our consciousness the sensation of red, and we say "That is a red object."

Which of the following is a detail from that passage about white light?

      About forty years ago, M. Henry Dimont, a native of Switzerland, having witnessed the unnecessary suffering of the wounded, from lack of care, at the battle of Solferino, was so much impressed that he published a book, pointing out the necessity of forming a corporation of nurses to work in the cause of humanity in time of war, regardless of nationality of the injured, and who should be permitted to aid the wounded on the battle-field, under the protection of a flag which should be recognized as neutral.

      So much interest was taken in the idea that the outcome was a convention held at Geneva in 1864, which was attended by representatives from sixteen of the great nations of the world, who signed an agreement that they would protect members of the association when caring for the wounded on the field of battle. The society adopted for its colors the Swiss cross, as a compliment to its birthplace; they, however, reversed the colors, and the flag is therefore a red cross on a white field, and is the only military hospital flag of civilized warfare; it protects persons from molestation who work under the emblem performing services in aid of the wounded.

      It was decided that the work of the Red Cross Society should not be confined to times of war, but that in case of disasters and calamities, which were always to be apprehended, the organization was to provide aid. During the past seventeen years the American Red Cross Society has served in fifteen disasters and famines, and Russians, Armenians, and Cubans have received aid from this society.

The ships of the Greeks were very different from modern vessels. Of course they were not driven by steam, nor did they rely as much on sails as modern sailing ships do. They had sails, but were driven forward mostly by their oars. The trireme, or ordinary war-ship, had its oars arranged in three banks, fifty men rowing at once. After these had rowed several hours, or a "watch," another fifty took their places, and finally a third fifty, so that the ships could be rowed at high speed all the time. With the aid of its two sails a trireme is said to have gone one hundred and fifty miles in a day and a night. These boats were about one hundred and twenty feet long and fifteen feet wide. They could be rowed in shallow water, but were not high enough to ride heavy seas safely. They had a sharp beak, which, driven against an enemy's ship, would break in its sides.

Which of the following is NOT true about the ancient Greek ships discussed in this passage?

Common ducks are about the same size as common fowls. As the duck in a state of nature lives much upon the water, its form is at nearly every point different from the typical form of the fowl. The duck is usually described as boat-shaped, but, while this is a good description, it would be more correct to say that a boat is duck-shaped. The duck was the natural model for the first builders of boats. The feet of a duck are webbed between the forward toes, which makes them more serviceable as paddles in swimming.

According to the passage, what is the benefit of webbed feet?

Some species of sharks grow to an enormous size, often weighing from one to four thousand pounds each. The skin of the shark is rough, and is used for polishing wood, ivory, &c.; that of one species is manufactured into an article called shagreen: spectacle-cases are made of it. The white shark is the sailor's worst enemy: he has five rows of wedge-shaped teeth, which are notched like a saw: when the animal is at rest they are flat in his mouth, but when about to seize his prey they are erected by a set of muscles which join them to the jaw. His mouth is so situated under the head that he is obliged to turn himself on one side before he can grasp any thing with those enormous jaws.

According to the passage, all of the following statements about sharks are true EXCEPT ___________________.

The natives of Australia were always few in number. Australia produced no grain of any sort naturally; neither wheat, oats, barley nor maize. It produced practically no edible fruit, excepting a few berries, and one or two nuts, the outer rind of which was eatable. There were no useful roots such as the potato, the turnip, or the yam, or the taro. The native animals were few and just barely eatable, the kangaroo, and the koala being the principal ones. In birds alone was the country well supplied, and they were more beautiful of plumage than useful as food. Even the fisheries were infrequent, for the coast line is unbroken by any great bays, and there is thus less sea frontage to Australia than to any other of the continents, and the rivers are few in number.

Based on the passage, which of the following statements is true?

Some years ago—never mind how long precisely—having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world.

A Lion lay asleep in the forest, his great head resting on his paws. A timid little Mouse came upon him unexpectedly, and in her fright and haste to get away, ran across the Lion's nose. Roused from his nap, the Lion laid his huge paw angrily on the tiny creature to kill her.

"Spare me!" begged the poor Mouse. "Please let me go and some day I will surely repay you."

The Lion was much amused to think that a Mouse could ever help him. But he was generous and finally let the Mouse go.

Some days later, while stalking his prey in the forest, the Lion was caught in the toils of a hunter's net. Unable to free himself, he filled the forest with his angry roaring. The Mouse knew the voice and quickly found the Lion struggling in the net. Running to one of the great ropes that bound him, she gnawed it until it parted, and soon the Lion was free.

"You laughed when I said I would repay you," said the Mouse. "Now you see that even a Mouse can help a Lion."

The Egyptian writing was certainly the quaintest, and perhaps the prettiest, that has ever been known. It is called "hieroglyphic," which means "sacred carving," and it is nothing but little pictures from beginning to end. The Egyptians began by putting down a picture of the thing which was represented by the word they wanted to use, and, though by-and-by they formed a sort of alphabet to spell words with, and had, besides, signs that represented the different syllables of a word, still, these signs were all little pictures. For instance, one of their signs for a was the figure of an eagle; their sign for m was a lion, and for u a little chicken; so that when you look at an Egyptian book written in the hieroglyphic character, you see column after column of birds and beasts and creeping things, of men and women and boats, and all sorts of other things, marching across the page.
