Adapted from "Bats" by W. S. Dallas in A Book of Natural History (1902, ed. David Starr Jordan)
Like the owls, with which they share the dominion of the evening air, the bats have a perfectly noiseless flight; their activity is chiefly during the twilight, although some species are later, and in fact seem to keep up throughout the whole night. As they rest during the day, concealed usually in the most inaccessible places they can find, and are seen only upon the wing, their power of flight is their most striking peculiarity in the popular mind, and it is perhaps no great wonder that by many people, both in ancient and modern times, they have been regarded as birds. Nevertheless, their hairy bodies and leathery wings are so unlike anything that we ordinarily understand as pertaining to a bird, that opinion was apparently always divided, as to the true nature of these creatures—“a mouse with wings,” as Goldsmith called it once, according to James Boswell, is certainly a curious animal, and very difficult to classify so long as the would-be systematist has no particularly definite ideas to guide him. The likeness of the bat to a winged mouse has made itself felt in the name given to the creature in many languages, such as the “chauvesouris” of the French and the “flitter-mouse” of some parts of England, the latter being reproduced almost literally in German, Dutch, and Swedish, while the Danes called the bat a “flogenmues,” which has about the same meaning.

The author discusses "the likeness of the Bat to a winged mouse" immediately before he introduces the names of the bat in various languages. The English name is even “flitter-mouse,” so it is clear that the author is trying to highlight “the similarities between a bat and a mouse in popular understanding."

Adapted from "The Wild Llama" by Charles Darwin in A Book of Natural History (1902, ed. David Starr Jordan)
The wild llama is the characteristic quadruped of the plains of Patagonia; it is the South American representative of the camel in the East. It is an elegant animal in a state of nature, with a long slender neck and fine legs. It is very common over the whole of the temperate parts of the continent, as far south as the islands near Cape Horn. It generally lives in small herds of from half a dozen to thirty in each, but on the banks of the St. Cruz we saw one herd which must have contained at least five hundred.
They are generally wild and extremely wary. Mr. Stokes told me that he one day saw through a glass a herd of these animals which evidently had been frightened and were running away at full speed, although they were so far away that he could not distinguish them with his naked eye. The sportsman frequently receives the first notice of their presence by hearing from a long distance their peculiar shrill, neighing note of alarm. If he then looks attentively, he will probably see the herd standing in a line on the side of some distant hill. On approaching nearer, a few more squeals are given, and off they set at an apparently slow, but really quick canter, along some narrow beaten track to a neighboring hill. If, however, by chance, he abruptly meets a single animal, or several together, they will generally stand motionless and intently gaze at him, then perhaps move on a few yards, turn round, and look again. What is the cause of this difference in their shyness? Do they mistake a man in the distance for their chief enemy, the puma? Or does curiosity overcome their timidity?

The primary purpose of the first paragraph is to provide some introductory information about wild llamas. Although the author does describe the size of the herds in which they move and explains where they can be found in the wild, the fact that he does each of these means that we cannot say that either is his primary purpose. Instead, both are part of the larger purpose of providing some introduction. The author does not go on to characterize the behavior of llamas until the second paragraph.

Adapted from Volume Four of The Natural History of Animals: The Animal Life of the World in Its Various Aspects and Relations by James Richard Ainsworth Davis (1903)
The examples of protective resemblance so far quoted are mostly permanent adaptations to one particular sort of surrounding. There are, however, numerous animals which possess the power of adjusting their color more or less rapidly so as to harmonize with a changing environment.
Some of the best known of these cases are found among those mammals and birds that inhabit countries more or less covered with snow during a part of the year. A good instance is afforded by the Irish or variable hare, which is chiefly found in Ireland and Scotland. In summer, this looks very much like an ordinary hare, though rather grayer in tint and smaller in size, but in winter it becomes white with the exception of the black tips to the ears. Investigations that have been made on the closely allied American hare seem to show that the phenomenon is due to the growth of new hairs of white hue.
The common stoat is subject to similar color change in the northern parts of its range. In summer it is of a bright reddish brown color with the exception of the under parts, which are yellowish white, and the end of the tail, which is black. But in winter, the entire coat, save only the tip of the tail, becomes white, and in that condition the animal is known as an ermine. A similar example is afforded by the weasel. The seasonal change in the vegetarian Irish hare is purely of protective character, but in such an actively carnivorous creature as a stoat or weasel, it is aggressive as well, rendering the animal inconspicuous to its prey.

When answering questions about a paragraph’s purpose, it’s helpful to consider how it relates to the rest of the passage as a whole, and to consider what each of the other paragraphs do in the context of the passage. For instance, in this passage, the first paragraph transitions from discussing animal adaptations in unchanging environments to discussing animal adaptations in changing environments. The second paragraph talks about Irish hares as an example of animals that change their fur color. So, what is the point of the third paragraph? While it does “provide an example of an animal that goes by two different names depending on its appearance” and “describe the appearance of a stoat in summer,” neither of these is its main point; these are details, and neither seems to relate that much to the points of the previous paragraphs. Stoats and weasels are not described as specifically hunting Irish hares, and the passage describes how their changing fur color helps them be better hunters, not why they have such a hard time hunting, so “to describe why stoats and weasels have a hard time hunting Irish hares in winter” cannot be the correct answer either. The point of the paragraph cannot be “to describe an animal that has adapted to an unchanging environment” either, because it describes stoats and weasels, animals that adapt to changing environments. This leaves us with one answer, the correct one: “to provide an example color-change in animals that is both aggressive and defensive.” The examples of stoats and weasels both fall into this category, which is contrasted with the purely defensive function of color-change in hares in the passage’s last sentence.

Where would one most likely find this article reprinted? Well, we wouldn’t be likely to find it in “a how-to manual” as it doesn’t explain how to do anything; it conveys information about certain types of animals. Similarly, since it doesn’t discuss physics or have anything to do with cooking, we can ignore the answers “A physics textbook” and “A cookbook.” This leaves us with “A scholarly report about weasels” and “An article in a biology magazine.” At this point we have to consider how the weasel is discussed in the passage—it is discussed very little, only in the context of being compared to the stoat or providing an example of carnivorous animals that change their fur color, along with the stoat. Given that the weasel isn’t the main subject of the passage, “An article in a biology magazine” is the best answer choice.

Adapted from Cassell’s Natural History by Francis Martin Duncan (1913)
The penguins are a group of birds inhabiting the southern ocean, for the most part passing their lives in the icy waters of the Antarctic seas. Like the ratitae, penguins have lost the power of flight, but the wings are modified into swimming organs and the birds lead an aquatic existence and are scarcely seen on land except in the breeding season. They are curious-looking creatures that appear to have no legs, as the limbs are encased in the skin of the body and the large flat feet are set so far back that the birds waddle along on land in an upright position in a very ridiculous manner, carrying their long narrow flippers held out as if they were arms. When swimming, penguins use their wings as paddles while the feet are used for steering.
Penguins are usually gregarious—in the sea, they swim together in schools, and on land, assemble in great numbers in their rookeries. They are very methodical in their ways, and on leaving the water, the birds always follow well-defined tracks leading to the rookeries, marching with much solemnity one behind the other in soldierly order.
The largest species of penguins are the king penguin and the emperor penguin, the former being found in Kerguelen Land, the Falklands, and other southern islands, and the latter in Victoria Land and on the pack ice of the Antarctic seas. As they are unaccustomed from the isolation of their haunts to being hunted and persecuted by man, emperor penguins are remarkably fearless, and Antarctic explorers invading their territory have found themselves objects of curiosity rather than fear to the strange birds who followed them about as if they were much astonished at their appearance.
The emperor penguin lays but a single egg and breeds during the intense cold and darkness of the Antarctic winter. To prevent contact with the frozen snow, the bird places its egg upon its flat webbed feet and crouches down upon it so that it is well covered with the feathers. In spite of this precaution, many eggs do not hatch and the mortality amongst the young chicks is very great.

The passage is clearly about penguins and doesn't discuss rainforests or their conservation, so we can eliminate the answer choice “At the start of a speech about why we need to protect the rainforest.” From where, we can see that all of our answer choices relate to penguins, and two begin with “At the start of . . .” while two others begin with “At the end of . . .” The passage seems to present a very general introduction to penguins, at first telling us that they are “a group of birds.” Because the passage begins as if the reader has never before heard of or seen a penguin or pictures of one, we can infer that it would most likely appear near the beginning of some text about penguins. This leaves us with “At the start of a report about penguins” and “At the start of a novel in which some of the characters are penguins.” This passage is scientific and objective and doesn’t appear to come from a novel—it doesn’t introduce any characters and instead simply conveys factual information about penguins. This makes “At the start of a report about penguins” the best answer choice.

Similarly, since it doesn’t discuss physics or have anything to do with cooking, we can ignore the answers “A physics textbook” and “A cookbook.” This leaves us with “A scholarly report about weasels” and “An article in a biology magazine.” At this point we have to consider how the weasel is discussed in the passage—it is discussed very little, only in the context of being compared to the stoat or providing an example of carnivorous animals that change their fur color, along with the stoat. Given that the weasel isn’t the main subject of the passage, “An article in a biology magazine” is the best answer choice.

The penguins are a group of birds inhabiting the southern ocean, for the most part passing their lives in the icy waters of the Antarctic seas. Like the ratitae, penguins have lost the power of flight, but the wings are modified into swimming organs and the birds lead an aquatic existence and are scarcely seen on land except in the breeding season. They are curious-looking creatures that appear to have no legs, as the limbs are encased in the skin of the body and the large flat feet are set so far back that the birds waddle along on land in an upright position in a very ridiculous manner, carrying their long narrow flippers held out as if they were arms. When swimming, penguins use their wings as paddles while the feet are used for steering.
Penguins are usually gregarious—in the sea, they swim together in schools, and on land, assemble in great numbers in their rookeries. They are very methodical in their ways, and on leaving the water, the birds always follow well-defined tracks leading to the rookeries, marching with much solemnity one behind the other in soldierly order.
The largest species of penguins are the king penguin and the emperor penguin, the former being found in Kerguelen Land, the Falklands, and other southern islands, and the latter in Victoria Land and on the pack ice of the Antarctic seas. As they are unaccustomed from the isolation of their haunts to being hunted and persecuted by man, emperor penguins are remarkably fearless, and Antarctic explorers invading their territory have found themselves objects of curiosity rather than fear to the strange birds who followed them about as if they were much astonished at their appearance.
The emperor penguin lays but a single egg and breeds during the intense cold and darkness of the Antarctic winter. To prevent contact with the frozen snow, the bird places its egg upon its flat webbed feet and crouches down upon it so that it is well covered with the feathers. In spite of this precaution, many eggs do not hatch and the mortality amongst the young chicks is very great.

The passage is clearly about penguins and doesn't discuss rainforests or their conservation, so we can eliminate the answer choice “At the start of a speech about why we need to protect the rainforest.” From where, we can see that all of our answer choices relate to penguins, and two begin with “At the start of . . .” while two others begin with “At the end of . . .” The passage seems to present a very general introduction to penguins, at first telling us that they are “a group of birds.” Because the passage begins as if the reader has never before heard of or seen a penguin or pictures of one, we can infer that it would most likely appear near the beginning of some text about penguins. This leaves us with “At the start of a report about penguins” and “At the start of a novel in which some of the characters are penguins.” This passage is scientific and objective and doesn’t appear to come from a novel—it doesn’t introduce any characters and instead simply conveys factual information about penguins. This makes “At the start of a report about penguins” the best answer choice.

Adapted from "Bats" by W. S. Dallas in A Book of Natural History (1902, ed. David Starr Jordan)
Like the owls, with which they share the dominion of the evening air, the bats have a perfectly noiseless flight; their activity is chiefly during the twilight, although some species are later, and in fact seem to keep up throughout the whole night. As they rest during the day, concealed usually in the most inaccessible places they can find, and are seen only upon the wing, their power of flight is their most striking peculiarity in the popular mind, and it is perhaps no great wonder that by many people, both in ancient and modern times, they have been regarded as birds. Nevertheless, their hairy bodies and leathery wings are so unlike anything that we ordinarily understand as pertaining to a bird, that opinion was apparently always divided, as to the true nature of these creatures—“a mouse with wings,” as Goldsmith called it once, according to James Boswell, is certainly a curious animal, and very difficult to classify so long as the would-be systematist has no particularly definite ideas to guide him. The likeness of the bat to a winged mouse has made itself felt in the name given to the creature in many languages, such as the “chauvesouris” of the French and the “flitter-mouse” of some parts of England, the latter being reproduced almost literally in German, Dutch, and Swedish, while the Danes called the bat a “flogenmues,” which has about the same meaning.

Adapted from "The Wild Llama" by Charles Darwin in A Book of Natural History (1902, ed. David Starr Jordan)
The wild llama is the characteristic quadruped of the plains of Patagonia; it is the South American representative of the camel in the East. It is an elegant animal in a state of nature, with a long slender neck and fine legs. It is very common over the whole of the temperate parts of the continent, as far south as the islands near Cape Horn. It generally lives in small herds of from half a dozen to thirty in each, but on the banks of the St. Cruz we saw one herd which must have contained at least five hundred.
They are generally wild and extremely wary. Mr. Stokes told me that he one day saw through a glass a herd of these animals which evidently had been frightened and were running away at full speed, although they were so far away that he could not distinguish them with his naked eye. The sportsman frequently receives the first notice of their presence by hearing from a long distance their peculiar shrill, neighing note of alarm. If he then looks attentively, he will probably see the herd standing in a line on the side of some distant hill. On approaching nearer, a few more squeals are given, and off they set at an apparently slow, but really quick canter, along some narrow beaten track to a neighboring hill. If, however, by chance, he abruptly meets a single animal, or several together, they will generally stand motionless and intently gaze at him, then perhaps move on a few yards, turn round, and look again. What is the cause of this difference in their shyness? Do they mistake a man in the distance for their chief enemy, the puma? Or does curiosity overcome their timidity?

The examples of protective resemblance so far quoted are mostly permanent adaptations to one particular sort of surrounding. There are, however, numerous animals which possess the power of adjusting their color more or less rapidly so as to harmonize with a changing environment.
Some of the best known of these cases are found among those mammals and birds that inhabit countries more or less covered with snow during a part of the year. A good instance is afforded by the Irish or variable hare, which is chiefly found in Ireland and Scotland. In summer, this looks very much like an ordinary hare, though rather grayer in tint and smaller in size, but in winter it becomes white with the exception of the black tips to the ears. Investigations that have been made on the closely allied American hare seem to show that the phenomenon is due to the growth of new hairs of white hue.
The common stoat is subject to similar color change in the northern parts of its range. In summer it is of a bright reddish brown color with the exception of the under parts, which are yellowish white, and the end of the tail, which is black. But in winter, the entire coat, save only the tip of the tail, becomes white, and in that condition the animal is known as an ermine. A similar example is afforded by the weasel. The seasonal change in the vegetarian Irish hare is purely of protective character, but in such an actively carnivorous creature as a stoat or weasel, it is aggressive as well, rendering the animal inconspicuous to its prey.

When answering questions about a paragraph’s purpose, it’s helpful to consider how it relates to the rest of the passage as a whole, and to consider what each of the other paragraphs do in the context of the passage. For instance, in this passage, the first paragraph transitions from discussing animal adaptations in unchanging environments to discussing animal adaptations in changing environments. The second paragraph talks about Irish hares as an example of animals that change their fur color. So, what is the point of the third paragraph? While it does “provide an example of an animal that goes by two different names depending on its appearance” and “describe the appearance of a stoat in summer,” neither of these is its main point; these are details, and neither seems to relate that much to the points of the previous paragraphs. Stoats and weasels are not described as specifically hunting Irish hares, and the passage describes how their changing fur color helps them be better hunters, not why they have such a hard time hunting, so “to describe why stoats and weasels have a hard time hunting Irish hares in winter” cannot be the correct answer either. The point of the paragraph cannot be “to describe an animal that has adapted to an unchanging environment” either, because it describes stoats and weasels, animals that adapt to changing environments. This leaves us with one answer, the correct one: “to provide an example color-change in animals that is both aggressive and defensive.” The examples of stoats and weasels both fall into this category, which is contrasted with the purely defensive function of color-change in hares in the passage’s last sentence.

Where would one most likely find this article reprinted? Well, we wouldn’t be likely to find it in “a how-to manual” as it doesn’t explain how to do anything; it conveys information about certain types of animals. Similarly, since it doesn’t discuss physics or have anything to do with cooking, we can ignore the answers “A physics textbook” and “A cookbook.” This leaves us with “A scholarly report about weasels” and “An article in a biology magazine.” At this point we have to consider how the weasel is discussed in the passage—it is discussed very little, only in the context of being compared to the stoat or providing an example of carnivorous animals that change their fur color, along with the stoat.

The penguins are a group of birds inhabiting the southern ocean, for the most part passing their lives in the icy waters of the Antarctic seas. Like the ratitae, penguins have lost the power of flight, but the wings are modified into swimming organs and the birds lead an aquatic existence and are scarcely seen on land except in the breeding season. They are curious-looking creatures that appear to have no legs, as the limbs are encased in the skin of the body and the large flat feet are set so far back that the birds waddle along on land in an upright position in a very ridiculous manner, carrying their long narrow flippers held out as if they were arms. When swimming, penguins use their wings as paddles while the feet are used for steering.
Penguins are usually gregarious—in the sea, they swim together in schools, and on land, assemble in great numbers in their rookeries. They are very methodical in their ways, and on leaving the water, the birds always follow well-defined tracks leading to the rookeries, marching with much solemnity one behind the other in soldierly order.
The largest species of penguins are the king penguin and the emperor penguin, the former being found in Kerguelen Land, the Falklands, and other southern islands, and the latter in Victoria Land and on the pack ice of the Antarctic seas. As they are unaccustomed from the isolation of their haunts to being hunted and persecuted by man, emperor penguins are remarkably fearless, and Antarctic explorers invading their territory have found themselves objects of curiosity rather than fear to the strange birds who followed them about as if they were much astonished at their appearance.
The emperor penguin lays but a single egg and breeds during the intense cold and darkness of the Antarctic winter. To prevent contact with the frozen snow, the bird places its egg upon its flat webbed feet and crouches down upon it so that it is well covered with the feathers. In spite of this precaution, many eggs do not hatch and the mortality amongst the young chicks is very great.

The passage is clearly about penguins and doesn't discuss rainforests or their conservation, so we can eliminate the answer choice “At the start of a speech about why we need to protect the rainforest.” From where, we can see that all of our answer choices relate to penguins, and two begin with “At the start of . . .” while two others begin with “At the end of . . .” The passage seems to present a very general introduction to penguins, at first telling us that they are “a group of birds.” Because the passage begins as if the reader has never before heard of or seen a penguin or pictures of one, we can infer that it would most likely appear near the beginning of some text about penguins. This leaves us with “At the start of a report about penguins” and “At the start of a novel in which some of the characters are penguins.” This passage is scientific and objective and doesn’t appear to come from a novel—it doesn’t introduce any characters and instead simply conveys factual information about penguins. This makes “At the start of a report about penguins” the best answer choice.

The examples of protective resemblance so far quoted are mostly permanent adaptations to one particular sort of surrounding. There are, however, numerous animals which possess the power of adjusting their color more or less rapidly so as to harmonize with a changing environment.
Some of the best known of these cases are found among those mammals and birds that inhabit countries more or less covered with snow during a part of the year. A good instance is afforded by the Irish or variable hare, which is chiefly found in Ireland and Scotland. In summer, this looks very much like an ordinary hare, though rather grayer in tint and smaller in size, but in winter it becomes white with the exception of the black tips to the ears. Investigations that have been made on the closely allied American hare seem to show that the phenomenon is due to the growth of new hairs of white hue.
The common stoat is subject to similar color change in the northern parts of its range. In summer it is of a bright reddish brown color with the exception of the under parts, which are yellowish white, and the end of the tail, which is black. But in winter, the entire coat, save only the tip of the tail, becomes white, and in that condition the animal is known as an ermine. A similar example is afforded by the weasel. The seasonal change in the vegetarian Irish hare is purely of protective character, but in such an actively carnivorous creature as a stoat or weasel, it is aggressive as well, rendering the animal inconspicuous to its prey.

When answering questions about a paragraph’s purpose, it’s helpful to consider how it relates to the rest of the passage as a whole, and to consider what each of the other paragraphs do in the context of the passage. For instance, in this passage, the first paragraph transitions from discussing animal adaptations in unchanging environments to discussing animal adaptations in changing environments. The second paragraph talks about Irish hares as an example of animals that change their fur color. So, what is the point of the third paragraph? While it does “provide an example of an animal that goes by two different names depending on its appearance” and “describe the appearance of a stoat in summer,” neither of these is its main point; these are details, and neither seems to relate that much to the points of the previous paragraphs. Stoats and weasels are not described as specifically hunting Irish hares, and the passage describes how their changing fur color helps them be better hunters, not why they have such a hard time hunting, so “to describe why stoats and weasels have a hard time hunting Irish hares in winter” cannot be the correct answer either. The point of the paragraph cannot be “to describe an animal that has adapted to an unchanging environment” either, because it describes stoats and weasels, animals that adapt to changing environments. This leaves us with one answer, the correct one: “to provide an example color-change in animals that is both aggressive and defensive.” The examples of stoats and weasels both fall into this category, which is contrasted with the purely defensive function of color-change in hares in the passage’s last sentence.

Where would one most likely find this article reprinted? Well, we wouldn’t be likely to find it in “a how-to manual” as it doesn’t explain how to do anything; it conveys information about certain types of animals. Similarly, since it doesn’t discuss physics or have anything to do with cooking, we can ignore the answers “A physics textbook” and “A cookbook.” This leaves us with “A scholarly report about weasels” and “An article in a biology magazine.” At this point we have to consider how the weasel is discussed in the passage—it is discussed very little, only in the context of being compared to the stoat or providing an example of carnivorous animals that change their fur color, along with the stoat. Given that the weasel isn’t the main subject of the passage, “An article in a biology magazine” is the best answer choice.

Adapted from "Bats" by W. S. Dallas in A Book of Natural History (1902, ed. David Starr Jordan)
Like the owls, with which they share the dominion of the evening air, the bats have a perfectly noiseless flight; their activity is chiefly during the twilight, although some species are later, and in fact seem to keep up throughout the whole night. As they rest during the day, concealed usually in the most inaccessible places they can find, and are seen only upon the wing, their power of flight is their most striking peculiarity in the popular mind, and it is perhaps no great wonder that by many people, both in ancient and modern times, they have been regarded as birds. Nevertheless, their hairy bodies and leathery wings are so unlike anything that we ordinarily understand as pertaining to a bird, that opinion was apparently always divided, as to the true nature of these creatures—“a mouse with wings,” as Goldsmith called it once, according to James Boswell, is certainly a curious animal, and very difficult to classify so long as the would-be systematist has no particularly definite ideas to guide him. The likeness of the bat to a winged mouse has made itself felt in the name given to the creature in many languages, such as the “chauvesouris” of the French and the “flitter-mouse” of some parts of England, the latter being reproduced almost literally in German, Dutch, and Swedish, while the Danes called the bat a “flogenmues,” which has about the same meaning.

Adapted from "The Wild Llama" by Charles Darwin in A Book of Natural History (1902, ed. David Starr Jordan)
The wild llama is the characteristic quadruped of the plains of Patagonia; it is the South American representative of the camel in the East. It is an elegant animal in a state of nature, with a long slender neck and fine legs. It is very common over the whole of the temperate parts of the continent, as far south as the islands near Cape Horn. It generally lives in small herds of from half a dozen to thirty in each, but on the banks of the St. Cruz we saw one herd which must have contained at least five hundred.
They are generally wild and extremely wary. Mr. Stokes told me that he one day saw through a glass a herd of these animals which evidently had been frightened and were running away at full speed, although they were so far away that he could not distinguish them with his naked eye. The sportsman frequently receives the first notice of their presence by hearing from a long distance their peculiar shrill, neighing note of alarm. If he then looks attentively, he will probably see the herd standing in a line on the side of some distant hill. On approaching nearer, a few more squeals are given, and off they set at an apparently slow, but really quick canter, along some narrow beaten track to a neighboring hill. If, however, by chance, he abruptly meets a single animal, or several together, they will generally stand motionless and intently gaze at him, then perhaps move on a few yards, turn round, and look again. What is the cause of this difference in their shyness? Do they mistake a man in the distance for their chief enemy, the puma? Or does curiosity overcome their timidity?

The primary purpose of the first paragraph is to provide some introductory information about wild llamas. Although the author does describe the size of the herds in which they move and explains where they can be found in the wild, the fact that he does each of these means that we cannot say that either is his primary purpose. Instead, both are part of the larger purpose of providing some introduction. The author does not go on to characterize the behavior of llamas until the second paragraph.
