Passage 1 is adapted from Talleyrand et al., Report on Public Instruction. Originally published in 1791. Passage 2 is adapted from Mary Wollstonecraft, A Vindication of the Rights of Woman. Originally published in 1792. Talleyrand was a French diplomat; the Report was a plan for national education. Wollstonecraft, a British novelist and political writer, wrote Vindication in response to Talleyrand. Passage 1 -That half the human race is excluded by the other half from any participation in government; that they are native by birth but foreign by law in the very land where they were born; and that they are property owners yet have no direct influence or representation: are all political phenomena apparently impossible to explain on abstract principle. But on another level of ideas, the question changes and may be easily resolved. The purpose of all these institutions must be the happiness of the greatest number. Everything that leads us farther from this purpose is in error; everything that brings us closer is truth. If the exclusion from public employments decreed against women leads to a greater sum of mutual happiness for the two sexes, then this becomes a law that all Societies have been compelled to acknowledge and sanction. Any other ambition would be a reversal of our primary destinies; and it will never be in women's interest to change the assignment they have received. It seems to us incontestable that our common happiness, above all that of women, requires that they never aspire to the exercise of political rights and functions. Here we must seek their interests in the wishes of nature. Is it not apparent, that their delicate constitutions, their peaceful inclinations, and the many duties of motherhood, set them apart from strenuous habits and onerous duties, and summon them to gentle occupations and the cares of the home? And is it not evident that the great conserving principle of Societies, which makes the division of powers a source of harmony, has been expressed and revealed by nature itself, when it divided the functions of the two sexes in so obviously distinct a manner? This is sufficient; we need not invoke principles that are inapplicable to the question. Let us not make rivals of life's companions. You must, you truly must allow the persistence of a union that no interest, no rivalry, can possibly undo. Understand that the good of all demands this of you. Passage 2 -Contending for the rights of woman, my main argument is built on this simple principle, that if she be not prepared by education to become the companion of man, she will stop the progress of knowledge and virtue; for truth must be common to all, or it will be inefficacious with respect to its influence on general practice. And how can woman be expected to co-operate unless she know why she ought to be virtuous? unless freedom strengthen her reason till she comprehend her duty, and see in what manner it is connected with her real good? If children are to be educated to understand the true principle of patriotism, their mother must be a patriot; and the love of mankind, from which an orderly train of virtues spring, can only be produced by considering the moral and civil interest of mankind; but the education and situation of woman, at present, shuts her out from such investigations... Consider, sir, dispassionately, these observations `" for a glimpse of this truth seemed to open before you when you observed, `that to see one half of the human race excluded by the other from all participation of government, was a political phenomenon that, according to abstract principles, it was impossible to explain.` If so, on what does your constitution rest? If the abstract rights of man will bear discussion and explanation, those of woman, by a parity of reasoning, will not shrink from the same test: though a different opinion prevails in this country, built on the very arguments which you use to justify the oppression of woman `" prescription. Consider `" I address you as a legislator `" whether, when men contend for their freedom, and to be allowed to judge for themselves respecting their own happiness, it be not inconsistent and unjust to subjugate women, even though you firmly believe that you are acting in the manner best calculated to promote their happiness? Who made man the exclusive judge, if woman partake with him the gift of reason? In this style, argue tyrants of every denomination, from the weak king to the weak father of a family; they are all eager to crush reason; yet always assert that they usurp its throne only to be useful. Do you not act a similar part, when you force all women, by denying them civil and political rights, to remain immured in their families groping in the dark? The authors of both passages would most likely agree with which of the following statements about women in the eighteenth century?

  1. Their natural preferences were the same as those of men.
  2. They needed a good education to be successful in society.
  3. They were just as happy in life as men were.
  4. They generally enjoyed fewer rights than men did.

Answer(s): D

Explanation:

Correct answer: D – They generally enjoyed fewer rights than men did.
Why D is the only statement both authors would endorse
Passage 1 (Talleyrand) explicitly frames women’s exclusion from public office as a “political phenomenon” that must be accepted because “our common happiness… requires that they never aspire to the exercise of political rights and functions.” The language treats the denial of political rights as a natural, pre-ordained condition, implying that women’s legal status is deliberately limited. Passage 2 (Wollstonecraft) confronts the same reality, asking “who made man the exclusive judge, if woman partake with him the gift of reason?” She points out that women are “immured in their families” and denied “civil and political rights.” Her critique is founded on the injustice of a system that “subjugates women” while claiming to promote their happiness. Both passages therefore share the premise that, in the eighteenth-century societal order, women possessed a subordinate legal and political status compared with men. This is precisely what option D states.
Why the other options do not fit

A: “Their natural preferences were the same as those of men.” Talleyrand argues the opposite: women’s “delicate constitutions, peaceful inclinations, and the many duties of motherhood” set them apart from the “strenuous habits” expected of men. Wollstonecraft likewise stresses that women’s education must cultivate reason and moral agency, which she sees as distinct from the prevailing male model. Hence, the authors do not claim identical natural preferences.
B: “They needed a good education to be successful in society.” While Wollstonecraft champions female education, she does so to enable women to fulfill their moral and social duties, not merely to achieve personal success. Talleyrand never discusses education as a prerequisite for women’s societal success; instead, he treats the existing limited education as sufficient for their “gentle occupations.” Therefore, the statement overstates a point that only one author emphasizes.
C: “They were just as happy in life as men were.” Both texts argue that women’s happiness is contingent on their exclusion from public life. Talleyrand claims that “the good of all demands” women remain in domestic roles, and Wollstonecraft suggests that without political rights women cannot fully contribute to the “progress of knowledge and virtue.” The authors imply that true happiness for women is tied to their prescribed, restricted roles, not to parity in happiness with men.
Conclusion The only option that captures the shared view of both authors—that women in the eighteenth century were systematically denied the same political and civil rights enjoyed by men—is D .

Do you not act a similar part, when you force all women, by denying them civil and political rights, to remain immured in their families groping in the dark? How would the authors of Passage 1 most likely respond to the points made in the final paragraph of Passage 2?

  1. Women are not naturally suited for the exercise of civil and political rights.
  2. Men and women possess similar degrees of reasoning ability.
  3. Women do not need to remain confined to their traditional family duties.
  4. The principles of natural law should not be invoked when considering gender roles.

Answer(s): A

Explanation:

Justification
Correct choice (A) – The excerpt from Passage 1 repeatedly argues that women’s “delicate constitutions,” “peaceful inclinations,” and “duties of motherhood” naturally confine them to “gentle occupations and the cares of the home.” It explicitly states that “our common happiness… requires that they never aspire to the exercise of political rights and functions.” This directly supports the claim that women are not naturally suited for civil and political participation, which is precisely what option A asserts.
Why the other options are unsuitable
B: “Men and women possess similar degrees of reasoning ability.” The passage never engages with a comparison of reasoning capacity; instead it emphasizes biological and social differences that justify exclusion. C. “Women do not need to remain confined to their traditional family duties.” This contradicts the passage’s stance, which defends the necessity of women’s traditional roles as essential to societal harmony. D. “The principles of natural law should not be invoked when considering gender roles.” The author actually does invoke a natural-law rationale, presenting the division of sexes as an expression of nature itself. Therefore this option misrepresents the text.
Conclusion – Option A aligns with the passage’s explicit claim that women’s nature precludes them from civil and political rights, making it the only answer fully consistent with the source material.

This passage is adapted from Richard J. Sharpe and Lisa Heyden, `Honey Bee Colony Collapse Disorder is Possibly Caused by a Dietary Pyrethrum Deficiency.` ֲ ©2009 by Elsevier Ltd. Colony collapse disorder is characterized by the disappearance of adult worker bees from hives. Honey bees are hosts to the pathogenic large ectoparasitic mite Varroa destructor (Varroa mites). These mites feed on bee hemolymph (blood) and can kill bees directly or by increasing their susceptibility to secondary infection with fungi, bacteria or viruses. Little is known about the natural defenses that keep the mite infections under control.
Pyrethrums are a group of flowering plants which include Chrysanthemum coccineum, Chrysanthemum cinerariifolium, Chrysanthemum marschalli, and related species. These plants produce potent insecticides with anti mite activity. The naturally occurring insecticides are known as pyrethrums. A synonym for the naturally occurring pyrethrums is pyrethrin and synthetic analogues of pyrethrums are known as pyrethroids. In fact, the human mite infestation known as scabies (Sarcoptes scabiei) is treated with a topical pyrethrum cream. We suspect that the bees of commercial bee colonies which are fed mono crops are nutritionally deficient. In particular, we postulate that the problem is a diet deficient in anti mite toxins: pyrethrums, and possibly other nutrients which are inherent in such plants. Without, at least, intermittent feeding on the pyrethrum producing plants, bee colonies are susceptible to mite infestations which can become fatal either directly or due to a secondary infection of immunocompromised or nutritionally deficient bees. This secondary infection can be viral, bacterial or fungal and may be due to one or more pathogens. In addition, immunocompromised or nutritionally deficient bees may be further weakened when commercially produced insecticides are introduced into their hives by bee keepers in an effort to fight mite infestation. We further postulate that the proper dosage necessary to prevent mite infestation may be better left to the bees, who may seek out or avoid pyrethrum containing plants depending on the amount necessary to defend against mites and the amount already consumed by the bees, which in higher doses could be potentially toxic to them. This hypothesis can best be tested by a trial wherein a small number of commercial honey bee colonies are offered a number of pyrethrum producing plants, as well as a typical bee food source such as clover, while controls are offered only the clover. Mites could then be introduced to each hive with note made as to the choice of the bees, and the effects of the mite parasites on the experimental colonies versus control colonies. It might be beneficial to test wild type honey bee colonies in this manner as well, in case there could be some genetic difference between them that affects the bees' preferences for pyrethrum producing flowers.

How do the words `can,` `may,` and `could` in the third paragraph help establish the tone of the paragraph?

  1. They create an optimistic tone that makes clear the authors are hopeful about the effects of their research on colony collapse disorder.
  2. They create a dubious tone that makes clear the authors do not have confidence in the usefulness of the research described.
  3. They create a tentative tone that makes clear the authors suspect but do not know that their hypothesis is correct.
  4. They create a critical tone that makes clear the authors are skeptical of claims that pyrethrums are inherent in mono crops.

Answer(s): C

Explanation:

When discussing problems with bee colonies, the authors use phrases like we suspect (sentence 1 of paragraph 3) and we postulate (sentence 2 of paragraph 3) to show they are hypothesizing reasons for bee colonies' susceptibility to mite infestations. The use of can, may, and could creates a tentative tone and provides further evidence that the authors believe, but are not certain, that their hypothesis is correct.

In sentence 1 of paragraph 4, the authors state that a certain hypothesis `can best be tested by a trial.` Based on the passage, which of the following is a hypothesis the authors suggest be tested in a trial?

  1. Honeybees that are exposed to both pyrethrums and mites are likely to develop a secondary infection by a virus, a bacterium, or a fungus.
  2. Beekeepers who feed their honeybee colonies a diet of a single crop need to increase the use of insecticides to prevent mite infestations.
  3. A honeybee diet that includes pyrethrums results in honeybee colonies that are more resistant to mite infestations.
  4. Humans are more susceptible to varroa mites as a result of consuming nutritionally deficient food crops.

Answer(s): C

Explanation:

In sentence 3 of paragraph 3, the authors hypothesize that bee colonies will be susceptible to mite infestations if they do not occasionally feed on pyrethrum producing plants. In sentence 1 of paragraph 4, they suggest creating a trial where a small number of commercial honey bee colonies are offered a number of pyrethrum producing plants to test their hypothesis. Other choices are incorrect because the authors do not hypothesize that honeybees' exposure to both pyrethrums and mites will cause the honeybees to develop secondary infections, that beekeepers should increase their use of insecticides, or that humans are more susceptible to varroa mites.

The passage most strongly suggests that beekeepers' attempts to fight mite infestations with commercially produced insecticides have what unintentional effect?

  1. They increase certain mite populations.
  2. They kill some beneficial forms of bacteria.
  3. They destroy bees' primary food source.
  4. They further harm the health of some bees.

Answer(s): D

Explanation:

The authors explain that when beekeepers use commercially produced insecticides to fight mite infections, they may further weaken bees that are immunocompromised or nutritionally deficient (sentence 5 of paragraph 3).

As used in sentence 6 of paragraph 3, `postulate` most nearly means to:

  1. make an unfounded assumption.
  2. put forth an idea or claim.
  3. question a belief or theory.
  4. conclude based on firm evidence.

Answer(s): B

Explanation:

Choice [put forth an idea or claim.] is the best answer. In sentence 5 of paragraph 3, the authors argue that beekeepers' use of insecticides to control mite infestations may be harmful to some bees. The authors then state, We further postulate that the proper dosage necessary to prevent mite infestation may be better left to the bees (sentence 6 of paragraph 3). In this context, the authors postulate, or put forth the idea that the bees may naturally control mite infestations better than insecticides. Other choices are incorrect because in this context, postulate does not mean to make an unfounded assumption, question a belief or theory, or conclude based on firm evidence.

The main purpose of the fourth paragraph is to:

  1. summarize the results of an experiment that confirmed the authors' hypothesis about the role of clover in the diets of wild-type honeybees.
  2. propose an experiment to investigate how different diets affect commercial honeybee colonies' susceptibility to mite infestations.
  3. provide a comparative nutritional analysis of the honey produced by the experimental colonies and by the control colonies.
  4. predict the most likely outcome of an unfinished experiment summarized in the third paragraph.

Answer(s): B

Explanation:

In the fourth paragraph the authors propose a trial to study if honeybees' consumption of pyrethrum producing plants helps the honeybees defend against mite infestations. In the experiment, the authors plan to offer honey bee colonies both pyrethrum producing plants and a typical bee food source such as clover to determine if these different diets affect the bees' susceptibility to mite infestations.

An unstated assumption made by the authors about clover is that the plants:

  1. do not produce pyrethrums.
  2. are members of the Chrysanthemum genus.
  3. are usually located near wild-type honeybee colonies.
  4. will not be a good food source for honeybees in the control colonies.

Answer(s): A

Explanation:
