Example Question #1 : Identifying And Analyzing Supporting Ideas In 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.

Which of the following provides an example of the main idea asserted in the first paragraph?

Possible Answers:

The Pythagorean theorem is based upon the constant relationship of the sides of a right triangle to its hypotenuse.

The fluctuation of coloration within a species is rather minimal.

None of the other answers

The interest in science only arises once agriculture reaches a certain point of fixity.

Religion constantly wanes with the rise of science.

Correct answer:

The Pythagorean theorem is based upon the constant relationship of the sides of a right triangle to its hypotenuse.

Explanation:

The first paragraph discusses the role of necessary connections and unvarying rules in scientific thinking, particularly the type of thinking that has played a prominent role in Western thought for many centuries. The example of the Pythagorean theorem is a good example of this.  Even if you do not know this mathematical equation, you can tell that this is the correct answer by the words "constant relationship."

Example Question #1 : Understanding Causes And Effects In Natural Science Passages

Adapted from “Humming-Birds: As Illustrating the Luxuriance of Tropical Nature” in Tropical Nature, and Other Essays by Alfred Russel Wallace (1878)

The food of hummingbirds has been a matter of much controversy. All the early writers down to Buffon believed that they lived solely on the nectar of flowers, but since that time, every close observer of their habits maintains that they feed largely, and in some cases wholly, on insects. Azara observed them on the La Plata in winter taking insects out of the webs of spiders at a time and place where there were no flowers. Bullock, in Mexico, declares that he saw them catch small butterflies, and that he found many kinds of insects in their stomachs. Waterton made a similar statement. Hundreds and perhaps thousands of specimens have since been dissected by collecting naturalists, and in almost every instance their stomachs have been found full of insects, sometimes, but not generally, mixed with a proportion of honey. Many of them in fact may be seen catching gnats and other small insects just like fly-catchers, sitting on a dead twig over water, darting off for a time in the air, and then returning to the twig. Others come out just at dusk, and remain on the wing, now stationary, now darting about with the greatest rapidity, imitating in a limited space the evolutions of the goatsuckers, and evidently for the same end and purpose. Mr. Gosse also remarks, ” All the hummingbirds have more or less the habit, when in flight, of pausing in the air and throwing the body and tail into rapid and odd contortions. This is most observable in the Polytmus, from the effect that such motions have on the long feathers of the tail. That the object of these quick turns is the capture of insects, I am sure, having watched one thus engaged pretty close to me.”

What evidence does Mr. Gosse have to support the claim that hummingbirds eat insects?

Possible Answers:

He examined the contents of a hummingbird’s stomach and found many insects in it.

He observed one flailing around in the air and concluded that it was eating insects.

A hummingbird got into his collection of live insects, and soon after, all of his insects were missing.

He read in a reputable scientific journal that they eat insects.

He surmised that they must eat insects because he has never seen one eating flower nectar.

Correct answer:

He observed one flailing around in the air and concluded that it was eating insects.

Explanation:

To answer this question, we have to consider the quotation attributed to Mr. Gosse found at the end of the passage:

“Mr. Gosse also remarks, ‘All the hummingbirds have more or less the habit, when in flight, of pausing in the air and throwing the body and tail into rapid and odd contortions. This is most observable in the Polytmus, from the effect that such motions have on the long feathers of the tail. That the object of these quick turns is the capture of insects, I am sure, having watched one thus engaged pretty close to me.’”

He doesn’t mention anything about having a collection of live insects, getting his information from a scientific journal, or dissecting a hummingbird’s stomach, so we can ignore those answer choices. He actively observes a hummingbird and surmises that they eat insects because of that, so the correct answer is “He observed one flailing around in the air and concluded that it was eating insects.”

Example Question #1 : Understanding And Evaluating Opinions And Arguments In Narrative Science Passages

Adapted from "Birds’ Nests" by John Burroughs in A Book of Natural History (1902, ed. David Starr Jordan)

How alert the birds are, even when absorbed in building their nests! In an open space in the woods, I see a pair of cedar-birds collecting moss from the top of a dead tree. Following the direction in which they fly, I soon discover the nest placed in the fork of a small soft-maple, which stands amid a thick growth of wild-cherry trees and young beeches. Carefully concealing myself beneath it, without any fear that the workmen will hit me with a chip or let fall a tool, I await the return of the busy pair. Presently I hear the well-known note, and the female sweeps down and settles unsuspectingly into the half-finished structure. Hardly have her wings rested, before her eye has penetrated my screen, and with a hurried movement of alarm, she darts away. In a moment, the male, with a tuft of wool in his beak (for there is a sheep pasture near), joins her, and the two reconnoitre the premises from the surrounding bushes. With their beaks still loaded, they move around with a frightened look, and refuse to approach the nest till I have moved off and lain down behind a log. Then one of them ventures to alight upon the nest, but, still suspecting all is not right, quickly darts away again. Then they both together come, and after much peeping and spying about, and apparently much anxious consultation, cautiously proceed to work. In less than half an hour, it would seem that wool enough has been brought to supply the whole family, real and prospective, with socks, if needles and fingers could be found fine enough to knit it up. In less than a week, the female has begun to deposit her eggs—four of them in as many days—white tinged with purple, with black spots on the larger end. After two weeks of incubation, the young are out.

In this passage the author is primarily concerned with describing the __________ nature of birds.

Possible Answers:

maternal

timid

vigilant

aggressive

industrious

Correct answer:

vigilant

Explanation:

The beginning of this passage is concerned with the author’s attempts to hide from the birds and observe them whilst they build their nest. But, the author understands that the birds quickly notice him, and he spends the remainder of this passage describing how the birds “vigilantly” try to determine what it is that is amiss about the area in which they have chosen to build their nest. In the introductory lines, the author says, “How alert the birds are, even when absorbed in building their nests!” This highlights his concern with outlining how “vigilant” the birds are. “Vigilant” and “alert” are synonyms of one another. To provide further help, “industrious” means hard-working; “timid” means shy; “aggressive” means likely to attack; and “maternal” means acting like a mother or related to mothers.

 

 

Example Question #171 : Science Passages

Adapted from "How the Soil is Made" by Charles Darwin in Wonders of Earth, Sea, and Sky (1902, ed. Edward Singleton Holden)

Worms have played a more important part in the history of the world than most persons would at first suppose. In almost all humid countries they are extraordinarily numerous, and for their size possess great muscular power. In many parts of England a weight of more than ten tons (10,516 kilograms) of dry earth annually passes through their bodies and is brought to the surface on each acre of land, so that the whole superficial bed of vegetable mould passes through their bodies in the course of every few years. From the collapsing of the old burrows, the mold is in constant though slow movement, and the particles composing it are thus rubbed together. Thus the particles of earth, forming the superficial mold, are subjected to conditions eminently favorable for their decomposition and disintegration. This keeps the surface of the earth perfectly suited to the growth of an abundant array of fruits and vegetables.

Worms are poorly provided with sense-organs, for they cannot be said to see, although they can just distinguish between light and darkness; they are completely deaf, and have only a feeble power of smell; the sense of touch alone is well developed. They can, therefore, learn little about the outside world, and it is surprising that they should exhibit some skill in lining their burrows with their castings and with leaves, and in the case of some species in piling up their castings into tower-like constructions. But it is far more surprising that they should apparently exhibit some degree of intelligence instead of a mere blind, instinctive impulse, in their manner of plugging up the mouths of their burrows. They act in nearly the same manner as would a man, who had to close a cylindrical tube with different kinds of leaves, petioles, triangles of paper, etc., for they commonly seize such objects by their pointed ends. But with thin objects a certain number are drawn in by their broader ends. They do not act in the same unvarying manner in all cases, as do most of the lower animals.

Worms are characterized as all of the following in this passage EXCEPT __________.

Possible Answers:

greatly underappreciated

surprisingly intelligent

extremely prolific

None of the other answers

immensely strong for their size

Correct answer:

None of the other answers

Explanation:

In this passage, worms are characterized as all of these answers. So, none of them is the exception. Early in the first paragraph, the author says, “In almost all humid countries they are extraordinarily numerous, and for their size possess great muscular power.” So, worms are “immensely strong for their size” and “extremely prolific.” “Prolific” and “numerous” both mean present in large numbers or plentiful. In the second paragraph, the author spends much of his time characterizing worms as “surprisingly intelligent,” as is shown in his focus on their ability to adapt to different circumstances when it comes to plugging their burrows. Finally, throughout the passage, worms are characterized as “greatly underappreciated.” This is notable in the second paragraph, where the author seems deeply impressed by the intelligence of worms, but most obviously notable in the first paragraph, where the author says “Worms have played a more important part in the history of the world than most persons would at first suppose.”

Example Question #1 : Main Ideas In Natural Science Passages

But with thin objects a certain number are drawn in by their broader ends. They do not act in the same unvarying manner in all cases, as do most of the lower animals.

What “important part in the history of the world” does the author believe worms have played?

Possible Answers:

They recycle the surface layer of soil, keeping it fresh and fertile.

They break up rocks, keeping the earth level and flat.

They provide food for birds, maintaining bird populations around the world.

They consume waste, keeping the earth clean and healthy.

They demonstrate intelligence, providing evidence of non-human sentience.

Correct answer:

They recycle the surface layer of soil, keeping it fresh and fertile.

Explanation:

The first paragraph is essentially one long explanation about the very important role that worms have played in history of the world. The author begins by saying “Worms have played a more important part in the history of the world than most persons would at first suppose.” The author then goes on to describe the process by which they play this “important part.” And, finally, he concludes by saying “This keeps the surface of the earth perfectly suited to the growth of an abundant array of fruits and vegetables.” The key is to focus on the relationship between the opening and closing sentences of the first paragraph.

Example Question #1 : Argumentative Science Passages

Adapted from “Introduced Species That Have Become Pests” in Our Vanishing Wild Life, Its Extermination and Protection by William Temple Hornaday (1913)

The man who successfully transplants or "introduces" into a new habitat any persistent species of living thing assumes a very grave responsibility. Every introduced species is doubtful gravel until panned out. The enormous losses that have been inflicted upon the world through the perpetuation of follies with wild vertebrates and insects would, if added together, be enough to purchase a principality. The most aggravating feature of these follies in transplantation is that never yet have they been made severely punishable. We are just as careless and easygoing on this point as we were about the government of the Yellowstone Park in the days when Howell and other poachers destroyed our first national bison herd, and when caught red-handed—as Howell was, skinning seven Park bison cows—could not be punished for it, because there was no penalty prescribed by any law. Today, there is a way in which any revengeful person could inflict enormous damage on the entire South, at no cost to himself, involve those states in enormous losses and the expenditure of vast sums of money, yet go absolutely unpunished!

The gypsy moth is a case in point. This winged calamity was imported at Maiden, Massachusetts, near Boston, by a French entomologist, Mr. Leopold Trouvelot, in 1868 or 69. History records the fact that the man of science did not purposely set free the pest. He was endeavoring with live specimens to find a moth that would produce a cocoon of commercial value to America, and a sudden gust of wind blew out of his study, through an open window, his living and breeding specimens of the gypsy moth. The moth itself is not bad to look at, but its larvae is a great, overgrown brute with an appetite like a hog. Immediately Mr. Trouvelot sought to recover his specimens, and when he failed to find them all, like a man of real honor, he notified the State authorities of the accident. Every effort was made to recover all the specimens, but enough escaped to produce progeny that soon became a scourge to the trees of Massachusetts. The method of the big, nasty-looking mottled-brown caterpillar was very simple. It devoured the entire foliage of every tree that grew in its sphere of influence.

The gypsy moth spread with alarming rapidity and persistence. In course of time, the state authorities of Massachusetts were forced to begin a relentless war upon it, by poisonous sprays and by fire. It was awful! Up to this date (1912) the New England states and the United States Government service have expended in fighting this pest about $7,680,000!

The spread of this pest has been retarded, but the gypsy moth never will be wholly stamped out. Today it exists in Rhode Island, Connecticut, and New Hampshire, and it is due to reach New York at an early date. It is steadily spreading in three directions from Boston, its original point of departure, and when it strikes the State of New York, we, too, will begin to pay dearly for the Trouvelot experiment.

How does the author feel about Howell?

Possible Answers:

The author greatly dislikes Howell for his audacious disrespect for nature.

The author agrees with Howell that invasive species are often problematic.

The author is annoyed by Howell’s insistence that invasive species do not cause significant problems.

The author likes Howell because he helped identify a problem with the consequences available for environmental disruptors.

The author thinks that Howell made a great mistake in releasing Gypsy moths into the United States.

Correct answer:

The author greatly dislikes Howell for his audacious disrespect for nature.

Explanation:

Let’s look at the part of the first paragraph in which the author brings up Howell, paying attention to why he does so:

“The most aggravating feature of these follies in transplantation is that never yet have they been made severely punishable. We are just as careless and easygoing on this point as we were about the government of the Yellowstone Park in the days when Howell and other poachers destroyed our first national bison herd, and when caught red-handed—as Howell was, skinning seven Park bison cows—could not be punished for it, because there was no penalty prescribed by any law.”

In mentioning Howell, the author is providing an example supporting his argument that harsher legal penalties are necessary for those who harm the environment. The author describes Howell as a “poacher” who “destroyed our first national bison herd” and was “caught red-handed.” From this, we can tell that the best answer choice is “the author greatly dislikes Howell for his audacious disrespect for nature.” 

One of the other answer choices attempts to get you to confuse Howell with Mr. Trouvelot, who released the gypsy moths—don’t fall for that! Check the passage if you are worried at all about confusing the two so you can avoid pitfall answers like that one.

The author’s tone in this passage is best described as __________

Possible Answers:

imaginative

optimistic

humorous

frustrated

sarcastic

Correct answer:

frustrated

Explanation:

Throughout the passage, the author laments that people who damage the environment by releasing invasive species cannot be legally punished for it, and provides the example of the gypsy moth as a particularly damaging invasive species. He takes his topic quite seriously, so we can’t call his tone “humorous.” He never uses sarcasm, so we can’t call it “sarcastic.” He doesn’t think that the United States will ever be rid of the gypsy moth, so we can’t call his tone “optimistic.” This leaves us with “imaginative” and “frustrated.” The author doesn’t use fanciful or figurative language in the passage, so we can’t accurately call his tone “imaginative.” “Frustrated” is the best answer. The author clearly wants to change the situation surrounding invasive species and the way in which those who introduce them are legally treated, but he cannot do anything to effect change in this area besides inform his readers of what’s wrong with the current system.

The description of the gypsy moth caterpillar found in the passage’s second paragraph suggests that the author __________ it.

Possible Answers:

detests

adores

respects

underestimates

misunderstands

Correct answer:

detests

Explanation:

How does the author describe the gypsy moth caterpillar in the second paragraph? Well, we can tell he’s not very fond of it at all because he says, “The moth itself is not bad to look at, but its larvae is a great, overgrown brute with an appetite like a hog.” Similarly, at the end of the paragraph, he writes, “Every effort was made to recover all the specimens, but enough escaped to produce progeny that soon became a scourge to the trees of Massachusetts. The method of the big, nasty-looking mottled-brown caterpillar was very simple. It devoured the entire foliage of every tree that grew in its sphere of influence.” Based on the strong negative language the author uses when discussing the gypsy moth caterpillars and the damage they cause, we can pick out “detests” as the correct answer.

The main reason the author mentions Howell’s story is __________.

Possible Answers:

to suggest that the loss of bison is a more important problem than those caused by the gypsy moth

to lament the loss of the United States’ first national bison herd

to argue for putting a fence up around Yellowstone National Park to keep out poachers

to attack Howell’s actions as reprehensible

to provide an account that shows how bad it is that environmental offenders cannot be legally punished

Correct answer:

to provide an account that shows how bad it is that environmental offenders cannot be legally punished

Explanation:

This question may initially seem tricky because Howell’s story accomplishes many of the answer choices’ statements: the author does attack Howell’s actions as reprehensible, and he does lament the loss of the United States’ first national bison herd. However, this are consequences of the story, not reasons why the author brought it up in the first place. The only answer choice that explains why the author mentions the story is “to provide an account that shows how bad it is that environmental offenders cannot be legally punished,” so this is the correct answer.

Today it exists in Rhode Island, Connecticut, and New Hampshire, and it is due to reach New York at an early date. It is steadily spreading in three directions from Boston, its original point of departure, and when it strikes the State of New York, we, too, will begin to pay dearly for the Trouvelot experiment.

Based on the context in which it is used, what is the most likely definition of the underlined word “entomologist”?

Possible Answers:

a scientist who studies invasive species

someone who causes and then solves a problem

a scientist who studies insects

someone who draws pictures of insects

a type of insect that eats other insects

Correct answer:

a scientist who studies insects

Explanation:

The word “entomologist” is used in the following part of the passage:

“The Gypsy Moth is a case in point. This winged calamity was imported at Maiden, Massachusetts, near Boston, by a French entomologist, Mr. Leopold Trouvelot, in 1868 or 69.” 

“Entomologist” is describing “Mr. Leopold Trouvelot,” so it cannot mean “a type of insect that eats other insects.” Nothing in the passage suggests that Mr. Trouvelot drew insects, so we can discard “someone who draws pictures of insects” as an answer choice. The answer “someone who causes and then solves a problem” doesn’t make sense either; while Mr. Trouvelot causes a problem by introducing the gypsy moth to the United States, he isn’t able to solve it. This leaves us with two answer choices: “a scientist who studies invasive species” and “a scientist who studies insects.” Nothing suggests that Mr. Trouvelot is a scientist who studies invasive species; indeed, at this point in the passage, the gypsy moth hasn’t even been released yet, so it is debatable whether we could call it an invasive species before it “invades.”
