Example Question #1 : Analyzing Main Idea, Theme, And Purpose In Natural Science Passages
Adapted from Common Diseases of Farm Animals by R. A. Craig (1916, 2nd ed.)
The common bot-fly of the horse (G. equi) has a heavy, hairy body. Its color is brown, with dark and yellowish spots. The female fly can be seen during the warm weather, hovering around the horse, and darting toward the animal for the purpose of depositing the egg. The color of the egg is yellow, and it adheres firmly to the hair. It hatches in from two to four weeks, and the larva reaches the mouth through the animal licking the part. From the mouth, it passes to the stomach, where it attaches itself to the gastric mucous membrane. Here it remains until fully developed, when it becomes detached and is passed out with the feces. The third stage is passed in the ground. This takes place in the spring and early summer and lasts for several weeks, when it finally emerges a mature fly.
The bot-fly of the ox (H. lineata) is dark in color and about the size of a honey-bee. On warm days, the female may be seen depositing eggs on the body of the animal, especially in the region of the heels. This seems to greatly annoy the animal, and it is not uncommon for cattle to become stampeded. The egg reaches the mouth through the animal licking the part. The saliva dissolves the shell of the egg and the larva is freed. It then migrates from the gullet, wanders about in the tissue until finally it may reach a point beneath the skin of the back. Here the larva matures and forms the well-known swelling or warble. In the spring of the year it works out through the skin. The next stage is spent in the ground. The pupa state lasts several weeks, when the mature fly issues forth.
The bot-fly of sheep (O. ovis) resembles an overgrown house-fly. Its general color is brown, and it is apparently lazy, flying about very little. This bot-fly makes its appearance when the warm weather begins, and deposits live larvae in the nostrils of sheep. This act is greatly feared by the animals, as shown by their crowding together and holding the head down. The larva works up the nasal cavities and reaches the sinuses of the head, where it becomes attached to the lining mucous membrane. In the spring, when fully developed, it passes out through the nasal cavities and nostrils, drops to the ground, buries itself, and in from four to six weeks develops into the mature fly.
SYMPTOMS OF BOT-FLY DISEASES.—The larvae of the bot-fly of the horse do not cause characteristic symptoms of disease. Work horses that are groomed daily are not hosts for a large number of "bots," but young and old horses that are kept in a pasture or lot and seldom groomed may become unthrifty and "pot bellied," or show symptoms of indigestion.
Cattle suffer much pain from the development of the larva of the H. lineata. During the spring of the year, the pain resulting from the presence of the larvae beneath the skin and the penetration of the skin is manifested by excitement and running about. Besides the loss in milk and beef production, there is a heavy yearly loss from the damage to hides.
The life of the bot-fly of sheep results in a severe catarrhal inflammation of the mucous membrane lining the sinuses of the head, and a discharge of a heavy, pus-like material from the nostrils. The irritation produced by the larvae may be so serious at times as to result in nervous symptoms and death.
Based on the passage, the primary purpose for the farm animals in the life cycle of the various types of bot-flies is to __________.
act as hosts for the eggs and larvae
provide them with dung to lay their eggs in
provide a source of food for adults
willingly nurture their young
distribute the flies over a large area
act as hosts for the eggs and larvae
The three descriptions of the different bot-flies tell us that each animals acts as a host for the egg and larval stages of the flies' lives. While the animals may aid in distributing the flies over a large area, this is not their primary purpose according to the passage.
Example Question #1 : Main Idea, Details, Opinions, And Arguments In Narrative Science Passages
Adapted from The Evolutionist at Large by Grant Allen (1881)
I am engaged in watching a brigade of ants out on foraging duty, and intent on securing for the nest three whole segments of a deceased earthworm. They look for all the world like those busy companies one sees in the Egyptian wall paintings, dragging home a huge granite colossus by sheer force of bone and sinew. Every muscle in their tiny bodies is strained to the utmost as they pry themselves laboriously against the great boulders that strew the path, and that are known to our Brobdingnagian intelligence as grains of sand. Besides the workers themselves, a whole battalion of stragglers runs to and fro upon the broad line that leads to the headquarters of the community. The province of these stragglers, who seem so busy doing nothing, probably consists in keeping communications open, and encouraging the sturdy pullers by occasional relays of fresh workmen. I often wish that I could for a while get inside those tiny brains, and see, or rather smell, the world as ants do. For there can be little doubt that to these brave little carnivores here the universe is chiefly known as a collective bundle of odors, simultaneous or consecutive. As our world is mainly a world of visible objects, theirs, I believe, is mainly a world of olfactible things.
In the head of every one of these little creatures is something that we may fairly call a brain. Of course most insects have no real brains; the nerve-substance in their heads is a mere collection of ill-arranged ganglia, directly connected with their organs of sense. Whatever man may be, an earwig at least is a conscious, or rather a semi-conscious, automaton. He has just a few knots of nerve cells in his little pate, each of which leads straight from his dim eye or his vague ear or his indefinite organs of taste; and his muscles obey the promptings of external sensations without possibility of hesitation or consideration, as mechanically as the valve of a steam engine obeys the governor balls. The poor soul's intellect is wholly deficient, and the senses alone make up all that there is of him, subjectively considered. But it is not so with the highest insects. They have something that truly answers to the real brain of men, apes, and dogs, to the cerebral hemispheres and the cerebellum that are superadded in us mammals upon the simple sense-centers of lower creatures. Besides the eye, with its optic nerve and optic perceptive organs—besides the ear, with its similar mechanism—we mammalian lords of creation have a higher and more genuine brain, that collects and compares the information given to the senses, and sends down the appropriate messages to the muscles accordingly. Now, bees and flies and ants have got much the same sort of arrangement, on a smaller scale, within their tiny heads. On top of the little knots that do duty as nerve centers for their eyes and mouths, stand two stalked bits of nervous matter, whose duty is analogous to that of our own brains. And that is why these three sorts of insects think and reason so much more intellectually than beetles or butterflies, and why the larger part of them have organized their domestic arrangements on such an excellent cooperative plan.
We know well enough what forms the main material of thought with bees and flies, and that is visible objects. For you must think about something if you think at all; and you can hardly imagine a contemplative blow-fly setting itself down to reflect, like a Hindu devotee, on the syllable Om, or on the oneness of existence. Abstract ideas are not likely to play a large part in apian consciousness. A bee has a very perfect eye, and with this eye it can see not only form, but also color, as Sir John Lubbock's experiments have shown us. The information that it gets through its eye, coupled with other ideas derived from touch, smell, and taste, no doubt makes up the main thinkable and knowable universe as it reveals itself to the apian intelligence. To ourselves and to bees alike the world is, on the whole, a colored picture, with the notions of distance and solidity thrown in by touch and muscular effort; but sight undoubtedly plays the first part in forming our total conception of things generally.
What is the main idea of the first paragraph?
The author is studying how ants use geological features to their advantage.
The author is pondering how history is like a swarm of ants.
The author is wishing he had a heightened sense of smell, like ants.
The author is watching ants and is considering their actions and how they perceive the world.
The author desires the ability to transform into an ant at will.
The author is watching ants and is considering their actions and how they perceive the world.
The paragraph as a whole describes a scene where the author is watching ants. This leads naturally into a discussion of how they may perceive the world, particularly through their sense of smell. Although the author does wish to have a heightened sense of smell and also compares the ants to events in history, these things do not encompass the entire paragraph.

One of the main points made in the second paragraph is __________.
Some insects brains are simple neural structures linked to their sensory organs.
Ants are no better than beetles or trains.
Ants, bees, and flies have neural parts corresponding to our own at the base of stalked nervous matter.
Insects with complex brains work less efficiently together.
Ants do not possess souls as humans and some mammals do.
Some insects brains are simple neural structures linked to their sensory organs.
The only justified answer is that which concerns the structure of some insects brains, as it is said in the paragraph that “[An earwig] has just a few knots of nerve cells in his little pate, each of which leads straight from his dim eye or his vague ear or his indefinite organs of taste; and his muscles obey the promptings of external sensations without possibility of hesitation or consideration.” While it could be inferred that the author does not think insects have souls, it is never stated and is not a main point of the paragraph.
Example Question #61 : Passage Based Questions
Adapted from “Darwin’s Predecessors” by J. Arthur Thomson in Evolution in Modern Thought (1917 ed.)
In seeking to discover Darwin's relation to his predecessors, it is useful to distinguish the various services which he rendered to the theory of organic evolution.
As everyone knows, the general idea of the doctrine of descent is that the plants and animals of the present day are the lineal descendants of ancestors on the whole somewhat simpler, that these again are descended from yet simpler forms, and so on backwards towards the literal "Protozoa" and "Protophyta" about which we unfortunately know nothing. Now no one supposes that Darwin originated this idea, which in rudiment at least is as old as Aristotle. What Darwin did was to make it current intellectual coin. He gave it a form that commended itself to the scientific and public intelligence of the day, and he won widespread conviction by showing with consummate skill that it was an effective formula to work with, a key which no lock refused. In a scholarly, critical, and preeminently fair-minded way, admitting difficulties and removing them, foreseeing objections and forestalling them, he showed that the doctrine of descent supplied a modal interpretation of how our present-day fauna and flora have come to be.
In the second place, Darwin applied the evolution-idea to particular problems, such as the descent of man, and showed what a powerful tool it is, introducing order into masses of uncorrelated facts, interpreting enigmas both of structure and function, both bodily and mental, and, best of all, stimulating and guiding further investigation. But here again it cannot be claimed that Darwin was original. The problem of the descent or ascent of man, and other particular cases of evolution, had attracted not a few naturalists before Darwin's day, though no one [except Herbert Spencer in the psychological domain (1855)] had come near him in precision and thoroughness of inquiry.
In the third place, Darwin contributed largely to a knowledge of the factors in the evolution-process, especially by his analysis of what occurs in the case of domestic animals and cultivated plants, and by his elaboration of the theory of natural selection, which Alfred Russel Wallace independently stated at the same time, and of which there had been a few previous suggestions of a more or less vague description. It was here that Darwin's originality was greatest, for he revealed to naturalists the many different forms—often very subtle—which natural selection takes, and with the insight of a disciplined scientific imagination he realized what a mighty engine of progress it has been and is.
What is the overall purpose of this passage?
To list some theories with which Darwin disagreed
To praise every aspect of Darwin's account of evolution
To provide comprehensive account of the history of Darwin's thought
To defend Darwin's account of evolution against those who deny its cogency
None of the other answers
None of the other answers
In this selection, the main idea is stated in the very first sentence, so long as you pay attention to it: "In seeking to discover Darwin's relation to his predecessors, it is useful to distinguish the various services which he rendered to the theory of organic evolution." The passage is directing our attention not to his predecessors per se. It is presenting "the various services which he rendered to the theory of organic evolution." It lists several such "services" that Darwin rendered in order to show how he helped to develop the theory of evolution in biology. None of the answers state this adequately.
Example Question #1 : Understanding Causes And Effects In Natural Science Passages
"Interpreting the Copernican Revolution" by Matthew Minerd (2014)
The expressions of one discipline can often alter the way that other subjects understand themselves. Among such cases are numbered the investigations of Nicolaus Copernicus. Copernicus is best known for his views concerning heliocentrism, a view which eventually obliterated many aspects of the ancient/medieval worldview, at least from the standpoint of physical science. It had always been the natural view of mankind that the earth stood at the center of the universe, a fixed point in reference to the rest of the visible bodies. The sun, stars, and planets all rotated around the earth.
With time, this viewpoint became one of the major reference points for modern life. It provided a provocative image that was used—and often abused—by many people for various purposes. For those who wished to weaken the control of religion on mankind, it was said that the heliocentric outlook proved man’s insignificance. In contrast with earlier geocentrism, heliocentrism was said to show that man is not the center of the universe. He is merely one small being in the midst of a large cosmos. However, others wished to use the “Copernican Revolution” in a very different manner. These thinkers wanted to show that there was another “recentering” that had to happen. Once upon a time, we talked about the world. Now, however, it was necessary to talk of man as the central reference point. Just as the solar system was “centered” on the sun, so too should the sciences be centered on the human person.
However, both of these approaches are fraught with problems. Those who wished to undermine the religious mindset rather misunderstood the former outlook on the solar system. The earlier geocentric mindset did not believe that the earth was the most important body in the heavens. Instead, many ancient and medieval thinkers believed that the highest “sphere” above the earth was the most important being in the physical universe. Likewise, the so-called “Copernican Revolution” in physics was different from the one applied to the human person. Copernicus’ revolution showed that the human point of view was not the center, whereas the later forms of “Copernican revolution” wished to show just the opposite.
Of course, there are many complexities in the history of such important changes in scientific outlook. Nevertheless, it is fascinating to see the wide-reaching effects of such discoveries, even when they have numerous, ambiguous effects.
What can we say of the effects of Copernicus’ discoveries on the reigning medieval way of looking at the world?
It completely discredited everything from the Middle Ages.
It had little effect in the final analysis.
It required significant changes in its natural science and its manner of considering the human person.
It questioned every received authority with detailed critiques.
It only effected the ideas concerning the human person in comparison with the vast universe.
It required significant changes in its natural science and its manner of considering the human person.
Clearly, the theories of Copernicus had significant effects on the medieval mindset. Although the passage does not indicate that it required complete revision on every point, it does imply that it had an effect both on the medieval conception of the human person as well as its scientific conceptions of the world.
Example Question #1 : Analyzing Cause And Effect In Natural Science Passages
"Darwinism's Effect on Science" by Matthew Minerd (2014)
For much of the history of human thought, the sciences have studied subjects that seemed to be eternal and unchanging. Even the basic laws of the Nile’s flooding were investigated in the hopes of finding never-altering laws. Similarly, the scientific investigations of the ancient Near East and Greece into the regular laws of the stars ultimately looked for constant patterns. This overall pattern of scientific reasoning has left deep marks on the minds of almost all thinkers and found its apotheosis in modern physics. From the time of the early renaissance to the nineteenth century, physics represented the ultimate expression of scientific investigation for almost all thinkers. Its static laws appeared to be the unchanging principles of all motion and life on earth. By the nineteenth century, it had appeared that only a few details had to be “cleared up” before all science was basically known.
In many ways, this situation changed dramatically with the arrival of Darwinism. It would change even more dramatically in early twentieth-century physics as well. Darwin’s theories of evolution challenged many aspects of the “static” worldview. Even those who did not believe that a divine being created an unchanging world were shaken by the new vistas opened up to science by his studies. It had been a long-accepted inheritance of Western culture to believe that the species of living organisms were unchanging in nature. Though there might be many different kinds of creatures, the kinds themselves were not believed to change. The thesis of a universal morphing of types shattered this cosmology, replacing the old world-view with a totally new one. Among the things that had to change in light of Darwin’s work was the very view of science held by most people.
Consider the underlined sentence. What was the new “cosmology” that arose after Darwin’s day?
The belief that history was an important but secondary aspect of scientific studies.
None of the other answers
A completely areligious outlook on life.
The view of the world as a changing reality with its own historical nature.
The view of the world as an unchanging whole to be investigated by science.
The view of the world as a changing reality with its own historical nature.
Throughout the second paragraph, the passage discusses again the "static" nature of the former scientific outlook. The new worldview was quite different. You can guess at the meaning of "cosmology" by noticing the contrast between it and "universal morphing of types." A "cosmology" is a particular outlook on the world or reality as a whole. The passage implies that Darwin's work made it necessary to see the world as a changing whole with its own history.

Adapted from “Feathers of Sea Birds and Wild Fowl for Bedding” from The Utility of Birds by Edward Forbush (ed. 1922)
In the colder countries of the world, the feathers and down of waterfowl have been in great demand for centuries as filling for beds and pillows. Such feathers are perfect non-conductors of heat, and beds, pillows, or coverlets filled with them represent the acme of comfort and durability. The early settlers of New England saved for such purposes the feathers and down from the thousands of wild-fowl which they killed, but as the population increased in numbers, the quantity thus furnished was insufficient, and the people sought a larger supply in the vast colonies of ducks and geese along the Labrador coast.
The manner in which the feathers and down were obtained, unlike the method practiced in Iceland, did not tend to conserve and protect the source of supply. In Iceland, the people have continued to receive for many years a considerable income by collecting eider down, but there they do not “kill the goose that lays the golden eggs.” Ducks line their nests with down plucked from their own breasts and that of the eider is particularly valuable for bedding. In Iceland, these birds are so carefully protected that they have become as tame and unsuspicious as domestic fowls In North America. Where they are constantly hunted they often conceal their nests in the midst of weeds or bushes, but in Iceland, they make their nests and deposit their eggs in holes dug for them in the sod. A supply of the ducks is maintained so that the people derive from them an annual income.
In North America, quite a different policy was pursued. The demand for feathers became so great in the New England colonies about the middle of the eighteenth century that vessels were fitted out there for the coast of Labrador for the express purpose of securing the feathers and down of wild fowl. Eider down having become valuable and these ducks being in the habit of congregating by thousands on barren islands of the Labrador coast, the birds became the victims of the ships’ crews. As the ducks molt all their primary feathers at once in July or August and are then quite incapable of flight and the young birds are unable to fly until well grown, the hunters were able to surround the helpless birds, drive them together, and kill them with clubs. Otis says that millions of wildfowl were thus destroyed and that in a few years their haunts were so broken up by this wholesale slaughter and their numbers were so diminished that feather voyages became unprofitable and were given up.
This practice, followed by the almost continual egging, clubbing, shooting, etc. by Labrador fishermen, may have been a chief factor in the extinction of the Labrador duck, that species of supposed restricted breeding range. No doubt had the eider duck been restricted in its breeding range to the islands of Labrador, it also would have been exterminated long ago.
Which of the following best states the main idea of this passage?
The Icelandic people collect eider down in an efficient and reasonable way.
The North American and Icelandic methods of collecting eider down have had vastly different consequences.
Natural resources are precious.
The extinction of the Labrador duck can be traced to a definite cause.
Eider down is valuable as a source of bedding, leading to its collection from ducks.
The North American and Icelandic methods of collecting eider down have had vastly different consequences.
Questions that ask about a passage’s main idea need to encompass each of the topics it discusses while not describing them in a way that is too broad. We can ignore any answer choices that only describe parts of the passage—here, “Eider down is valuable as a source of bedding, leading to its collection from ducks,” “The extinction of the Labrador duck can be traced to a definite cause,” and “The Icelandic people collect eider down in an efficient and reasonable way.” This leaves us with “Natural resources are precious,” which is far too broad to accurately describe the passage’s main idea, and the correct answer, “The North American and Icelandic methods of collecting eider down have had vastly different consequences.”

No doubt had the eider duck been restricted in its breeding range to the islands of Labrador, it also would have been exterminated long ago.
In the context of the passage as a whole, the fourth paragraph serves to __________.
detail further repercussions of the Labrador feather voyages
provide more historical details about how the Labrador feather voyages were organized
compare and contrast Icelandic and North American down-harvesting methods
describe why eider down is a valuable commodity
describe some of the benefits of the Labrador feather voyages
detail further repercussions of the Labrador feather voyages
Let’s look at what each paragraph is accomplishing in the context of the passage as a whole:
First paragraph: introduces and describes eider down
Second paragraph: describes Icelandic method of collecting eider down, which protects the duck population
Third paragraph: describes the North American method of collecting eider down, which destroys the duck population
Fourth paragraph: suggests that the Labrador feather voyages may have contributed to the extinction of the Labrador duck and says that they stopped because the duck populations were so much smaller that the trips were no longer profitable
Now that we have considered the structure of the passage’s argument as a whole, it should be easier to answer this question. “Compare and contrast Icelandic and North American down-harvesting methods” describes the second and third paragraphs, whereas “describe why eider down is a valuable commodity” describes the first paragraph. The Labrador feather voyages are cast in a negative light throughout the entire passage, so “describe some of the benefits of the Labrador feather voyages” cannot be the correct answer as benefits of them are never discussed. The fourth paragraph does not “provide more historical details about how the Labrador feather voyages were organized”; it describes their aftermath, so this answer choice cannot be correct. That the fourth paragraph serves to “detail further repercussions of the Labrador feather voyages” is the best answer choice. It discusses the effects of the Labrador feather voyages on the duck population and suggests that they may have contributed to the extinction of a particular species of duck that had a limited habitat.

"Comparing Technologies: A Difficult Endeavor" by Matthew Minerd (2014)
Comparisons of technology are often difficult to make, not only because of the rapid pace of improvements but also because of the many new applications that are available as time progresses. If we were to consider the contemporary graphing calculator and the calculation capacities of computing machines from fifty years ago, there would be astounding improvements between these two devices. However, the improvements are not reduced merely to speed improvements. A graphing calculator also has numerous output capacities that far exceed those available much older computers, none of which had the ability to represent their output in any manner even closely resembling that of contemporary devices. Merely consider the display capacities of such a device. These enable users to input many new kinds of information, enabling design engineers to design new hardware functions to match the new means of collecting user input.
The situation is even more obvious when one considers the numerous functions performed by a modern “smartphone.” These devices are equipped with a panoply of features. With all of these new functions come many new types of computational capabilities as well. In order to process images quickly, specialized hardware must be designed and software written for it in order to ensure that there are few issues with the phone’s operation. Indeed, the whole “real time” nature of telecommunications has exerted numerous pressures on the designers of computing devices. Layers of complexity, at all levels of production and development, are required to ensure that the phone can function in a synchronous manner. Gone are the days of asynchronous processing, when the computer user entered data into a mainframe, only to wait for a period of time before the processing results were provided. Today, even the smallest of digital devices must provide seamless service for users. The effects of this requirement are almost beyond number.
Which of the following best describes the contrast between newer and older calculating devices?
They differ both in capabilities as well as overall speed.
Older calculating machines broke down far more frequently than do modern calculators.
Newer calculators are blazingly faster than older calculating machines.
None of the other answers
Previous calculators had no output capacities whatsoever.
They differ both in capabilities as well as overall speed.
In the selection, there are two key sentences: "However, the improvements are not reduced merely to speed improvements. A graphing calculator also has numerous output capacities that far exceed those available much older computers." The passage marks two points regarding the difference between the older and newer devices. They differ both with regard to speed and their ability to output data. The answer that speaks of having differing "capabilities" captures the distinction in output well enough for our answer. The other answers either bring in data not listed in our passage or are too narrow in scope.

Layers of complexity, at all levels of production and development, are required to ensure that the phone can function in a synchronous manner. Gone are the days of asynchronous processing, when the computer user entered data into a mainframe, only to wait for a period of time before the processing results were provided. Today, even the smallest of digital devices must provide seamless service for users. The effects of this requirement are almost beyond number.
What is the effect of the features found on modern “smartphones”?
They require many new types of technological advancements to accommodate them.
None of the other answers
They wear out old equipment, requiring newer, faster processors.
They overwhelm the customer with options all on one screen.
They require increased memory capacities to accommodate their advancements.
They require many new types of technological advancements to accommodate them.
Although the whole of the second paragraph helps to answer this question, a key sentence is, "With all of these new functions come many new types of computational capabilities as well." The effect of the new capabilities is to require many different kinds of new capabilities for the software and hardware of phones. That is, many new technological advances are required in order to make them possible and more efficient.
