This excerpt is from The Life-Story of Insects by Geo H. Carpenter.
Insects as a whole are preeminently creatures of the land and the air. This is shown not only by the possession of wings by a vast majority of the class, but by the mode of breathing to which reference has already been made, a system of branching air-tubes carrying atmospheric air with its combustion-supporting oxygen to all the insect's tissues. The air gains access to these tubes through a number of paired air-holes or spiracles, arranged segmentally in series.
It is of great interest to find that, nevertheless, a number of insects spend much of their time under water. This is true of not a few in the perfect winged state, as for example aquatic beetles and water-bugs ('boatmen' and 'scorpions') which have some way of protecting their spiracles when submerged, and, possessing usually the power of flight, can pass on occasion from pond or stream to upper air. But it is advisable in connection with our present subject to dwell especially on some insects that remain continually under water till they are ready to undergo their final molt and attain the winged state, which they pass entirely in the air.
The preparatory instars of such insects are aquatic; the adult instar is aerial. All may-flies, dragon-flies, and caddis-flies, many beetles and two-winged flies, and a few moths thus divide their life-story between the water and the air. For the present we confine attention to the Stoneflies, the May-flies, and the Dragon-flies, three well-known orders of insects respectively called by systematists the Plecopteran, the Ephemeroptera, and the Odonata.
In the case of many insects that have aquatic larvae, the latter are provided with some arrangement for enabling them to reach atmospheric air through the surface-film of the water. But the larva of a stone-fly, a dragon-fly, or a may-fly is adapted more completely than these for aquatic life; it can, by means of gills of some kind, breathe the air dissolved in water.
What role do the spiracles play in the respiration of the insects described in the passage?
- A. They allow insects to breathe atmospheric air even when submerged.
- B. They protect the insect's internal organs from water pressure.
- C. They filter oxygen from the water for underwater breathing.
- D. They are used to expel carbon dioxide from the body.
Correct Answer: A
Rationale: The spiracles in insects serve the crucial function of allowing them to breathe atmospheric air even when submerged. The passage explains that insects have a system of branching air-tubes that carry atmospheric air with oxygen to all tissues. The air enters these tubes through paired air-holes or spiracles, enabling insects to respire even when they are underwater. Choices B, C, and D are incorrect because the spiracles do not protect internal organs from water pressure, filter oxygen from water for underwater breathing, or expel carbon dioxide from the body. The primary role of spiracles is to facilitate respiration by allowing insects to access atmospheric air.

This excerpt is from an analysis of The Importance of Being Earnest by Oscar Wilde.
Wilde's play, "The Importance of Being Earnest", is a satire that targets the absurdities and trivialities of the British aristocracy. The play's subtitle, 'A Trivial Comedy for Serious People,' aptly summarizes Wilde's intentions. Through clever dialogue, puns, and a healthy dose of irony, Wilde exposes the superficiality and hypocrisy of the upper classes.
The characters in the play, such as Jack Worthing and Algernon Moncrieff, lead double lives, reflecting the dual nature of their social standing. The use of 'Bunburying,' a term coined by Wilde, illustrates the lengths to which these characters go to escape their social obligations and lead a life of deceit. The play also pokes fun at the institution of marriage, which is depicted as a social contract rather than a romantic union.
For example, Lady Bracknell's interrogation of Jack regarding his suitability as a husband for her daughter Gwendolen reveals the transactional nature of marriage in the society Wilde is critiquing. Wilde's portrayal of the aristocracy is not merely critical, but also humorous, making The Importance of Being Earnest one of his most beloved and enduring works.
Which literary device is most prominent in Wilde's play?
- A. Irony
- B. Symbolism
- C. Metaphor
- D. Allusion
Correct Answer: A
Rationale: The correct answer is 'Irony.' Irony is the most prominent literary device in Wilde's play, 'The Importance of Being Earnest,' as it pervades his critique of the upper class. Throughout the play, Wilde uses irony to highlight the absurdities and trivialities of the British aristocracy. The characters engage in witty and humorous dialogue filled with situational irony, verbal irony, and dramatic irony, exposing the superficiality and hypocrisy of the upper classes. Symbolism, metaphor, and allusion are present in the play but to a lesser extent compared to irony. While symbolism and metaphor are used to enhance the themes and characterizations, allusion is sparingly employed. However, it is the pervasive use of irony that sets the tone and drives Wilde's satire of the societal norms and values of the time.

What is the author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air?
- A. To emphasize the adaptability and complexity of insect life cycles.
- B. To compare aquatic insects with those that remain airborne.
- C. To highlight the unique features of insects that live in both environments.
- D. To question the validity of studying insects that live in only one environment.
Correct Answer: A
Rationale: The author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air is to emphasize the adaptability and complexity of insect life cycles. The author highlights how some insects transition between aquatic and aerial environments, showcasing the diverse strategies and features these insects possess to thrive in different habitats. Choice B is incorrect because the author is not solely comparing aquatic insects with those that remain airborne, but rather exploring their adaptability. Choice C is incorrect as the focus is not on highlighting unique features but on showcasing the transition between environments. Choice D is incorrect as the author is not questioning the validity of studying insects in only one environment but rather demonstrating the fascinating dual-life cycles of certain insects.
This excerpt is from a speech by Charles Dickens delivered in Birmingham, England, on December 30, 1853, on behalf of the Birmingham and Midland Institute.
My Good Friends, when I first imparted to the committee of the projected Institute my particular wish that on one of the evenings of my readings here the main body of my audience should be composed of working men and their families, I was animated by two desires; first, by the wish to have the great pleasure of meeting you face to face at this Christmas time, and accompany you myself through one of my little Christmas books; and second, by the wish to have an opportunity of stating publicly in your presence, and in the presence of the committee, my earnest hope that the Institute will, from the beginning, recognize one great principle "strong in reason and justice" which I believe to be essential to the very life of such an Institution.
It is, that the working man shall, from the first unto the last, have a share in the management of an Institution which is designed for his benefit, and which calls itself by his name. I have no fear here of being misunderstood, of being supposed to mean too much in this. If there ever was a time when any one class could of itself do much for its own good, and for the welfare of society -which I greatly doubt- that time is unquestionably past. It is in the fusion of different classes, without confusion; in the bringing together of employers and employed; in the creating of a better common understanding among those whose interests are identical, who depend upon each other, who are vitally essential to each other, and who never can be in unnatural antagonism without deplorable results, that one of the chief principles of a Mechanic's Institution should consist.
In this world a great deal of the bitterness among us arises from an imperfect understanding of one another. Erect in Birmingham a great Educational Institution, properly educational; educational of the feelings as well as of the reason; to which all orders of Birmingham men contribute; in which all orders of Birmingham men meet; wherein all orders of Birmingham men are faithfully represented and you will erect a Temple of Concord here which will be a model edifice to the whole of England. Contemplating as I do the existence of the Artisan's Committee, which not long ago considered the establishment of the Institute so sensibly, and supported it so heartily, I earnestly entreat the gentlemen - earnest I know in the good work, and who are now among us- by all means to avoid the great shortcoming of similar institutions; and in asking the working man for his confidence, to set him the great example and give him theirs in return.
You will judge for yourselves if I promise too much for the working man, when I say that he will stand by such an enterprise with the utmost of his patience, his perseverance, sense, and support; that I am sure he will need no charitable aid or condescending patronage; but will readily and cheerfully pay for the advantages which it confers; that he will prepare himself in individual cases where he feels that the adverse circumstances around him have rendered it necessary; in a word, that he will feel his responsibility like an honest man, and will most honestly and manfully discharge it.
I now proceed to the pleasant task to which I assure you I have looked forward for a long time.
According to the extract, which of the following statements most closely correlates with the definition of the term 'working man'?
- A. A working man is someone who is well versed in the workings of the soul.
- B. A working man is probably not involved in social activities due to the high physical demand of work.
- C. A working man is someone who earns wages in a traditional sense, often associated with the middle class.
- D. The working man historically transitions from the field to the factory and now to the screen.
Correct Answer: C
Rationale: According to the extract, the term 'working man' refers to individuals who are actively employed and earn wages in a traditional sense. Charles Dickens emphasizes the importance of the working man having a share in the management of institutions designed for their benefit. This aligns with choice C, making it the correct answer. Choice A is incorrect as the extract does not mention anything about being well versed in the workings of the soul. Choice B is incorrect because the extract does not suggest that working men are not involved in social activities due to the physical demands of their work. Choice D is also incorrect as the extract does not focus on the historical transitions of the working man.
This excerpt is an adaptation of Jonathan Swift's "Gulliver's Travels into Several Remote Nations of the World".
My gentleness and good behavior had gained so far on the emperor and his court, and indeed upon the army and people in general, that I began to conceive hopes of getting my liberty in a short time. I took all possible methods to cultivate this favorable disposition. The natives came, by degrees, to be less apprehensive of any danger from me. I would sometimes lie down, and let five or six of them dance on my hand; and at last the boys and girls would venture to come and play at hide-and-seek in my hair.
I had now made good progress in understanding and speaking the language. The emperor had a mind one day to entertain me with several of the country shows, wherein they exceed all nations I have known, both for dexterity and magnificence. I was diverted with none so much as that of the rope-dancers, performed upon a slender white thread, extended about two feet, and twelve inches from the ground, Upon which I shall desire liberty, with the reader's patience, to enlarge a little.
This diversion is only practiced by those persons who are candidates for great employments, and high favor at court. They are trained in this art from their youth, and are not always of noble birth, or liberal education. When a great office is vacant, either by death or disgrace (which often happens,) five or six of those candidates petition the emperor to entertain his majesty and the court with a dance on the rope; and whoever jumps the highest, without falling, succeeds in the office.
Very often the chief ministers themselves are commanded to show their skill, and to convince the emperor that they have not lost their faculty. FlyNap, the treasurer, is allowed to cut a caper on the straight rope, at least an inch higher than any other lord in the whole empire. I have seen him do the somersault several times together, upon a trencher fixed on a rope which is no thicker than a common packthread in England. My friend Reldresal, principal secretary for private affairs, is, in my opinion, if I am not partial, the second after the treasurer; the rest of the great officers are much upon a par.

- A. Gulliver details his experiences and interactions with the natives of the new land.
- B. Gulliver observes the unique customs and traditions of the society he encounters.
- C. Gulliver becomes acquainted with the people and practices of his new surroundings.
- D. Gulliver reflects on the cultural differences between his homeland and the new land.
Correct Answer: C
Rationale: The correct answer is C because the text describes how Gulliver becomes familiar with the customs and practices of the new society he finds himself in. He interacts with the natives, learns their language, and participates in their shows, indicating his growing understanding and acceptance of the new culture. Choice A is incorrect because the text goes beyond detailing his experiences to focus on his growing familiarity with the society. Choice B is incorrect because Gulliver not only observes but actively engages with the customs. Choice D is incorrect as the focus is on Gulliver's adaptation rather than reflecting on cultural differences.
