41 How would the authors of Passage 1 most likely respond to the points made in the final paragraph of Passage 2? Passage 1 Here we must seek their interests in the wishes of nature... 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. Passage 2 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? A) Women are not naturally suited for the exercise of civil and political rights. B) Men and women possess similar degrees of reasoning ability. C) Women do not need to remain confined to their traditional family duties. D) The principles of natural law should not be invoked when considering gender roles.

And yet public transportation, in many minds, is the opposite of glamour—a squalid last resort for those with one too many impaired driving charges, too poor to afford insurance, or too decrepit to get behind the wheel of a car. In much of North America, they are right: taking transit is a depressing experience. Anybody who has waited far too long on a street corner for the privilege of boarding a lurching, overcrowded bus, or wrestled luggage onto subways and shuttles to get to a big city airport, knows that transit on this continent tends to be underfunded, ill-maintained, and ill-planned. Given the opportunity, who wouldn't drive? Hopping in a car almost always gets you to your destination more quickly 11 What function does the third paragraph (lines 20-34) serve in the passage as a whole?

C) It gives an overview of a problem that has not been sufficiently addressed by the experts mentioned in the passage. D) It advocates for abandoning a practice for which the passage as a whole provides mostly favorable data.

The questions that we have to ask and to answer about that procession during this moment of transition are so important that they may well change the lives of all men and women for ever. For we have to ask ourselves, here and now, do we wish to join that procession, or don't we? On what terms shall we join that procession? 33 The central claim of the passage is that A) educated women face a decision about how to engage with existing institutions. B) women can have positions of influence in English society only if they give up some of their traditional roles. C) the male monopoly on power in English society has had grave and continuing effects. D) the entry of educated women into positions of power traditionally held by men will transform those positions.

The author of Passage 2 would most likely respond to the discussion of the future of space mining in lines 18-28, Passage 1, by claiming that such a future (Within a few decades, these firms may be meeting earthly demands for precious metals, such as platinum and gold, and the rare earth elements vital for personal electronics, such as yttrium and lanthanum. But like the gold rush pioneers who transformed the western United States, the first space miners won't just enrich themselves.

Certain of her acquaintances were wont to give her plentiful admonition as to the undesirability of interfering on behalf of a distressed animal, such interference being "none of her business." Only once had she put the doctrine of non-interference into practice, when one of its most eloquent exponents had been besieged for nearly three hours in a small and extremely uncomfortable may-tree by an angry boar-pig, while Lady Carlotta, on the other side of the fence, had proceeded with the watercolor sketch she was engaged on, and refused to interfere between the boar and his prisoner. 5 The description of how Lady Carlotta "put the doctrine of non-interference into practice" (lines 14-15) mainly serves to A) foreshadow her capacity for deception. B) illustrate the subtle cruelty in her nature. C) provide a humorous insight into her character. D) explain a surprising change in her behavior.

Box's research is important because the fires of 2012 may not be a one-time phenomenon. According to scientists, rising Arctic temperatures are making northern latitudes greener and thus more fire prone. The pattern Box observed in 2012 may repeat 21 itself again, with harmful effects on the Arctic ecosystem. [4] Box is currently organizing an expedition to gather this crucial information. The next step for Box and his team is to travel to Greenland to perform direct sampling of the ice in order to determine just how much the soot is contributing to the melting of the ice sheet. Members of the public will be able to track his team's progress—and even help fund the expedition—through a website Box has created. 22 To make this paragraph most logical, sentence 4 should be placed A) where it is now. B) after sentence 1. C) after sentence 2. D) after sentence 5.

Lady Carlotta stepped out on to the platform of the small wayside station and took a turn or two up and down its uninteresting length, to kill time till the train should be pleased to proceed on its way..."It's gone astray," said the alleged governess, falling in with the excellent rule of life that the absent are always to blame; the luggage had, in point of fact, behaved with perfect correctitude. 1 Which choice best summarizes the passage? A) A woman weighs the positive and negative aspects of accepting a new job. B) A woman does not correct a stranger who mistakes her for someone else. C) A woman impersonates someone else to seek revenge on an acquaintance. D) A woman takes an immediate dislike to her new employer.

So when a group of graduate students challenged him to come up with new data on the age-old ground-up-tree-down debate, he designed a project to see what clues might lie in how baby game birds learned to fly... Ken settled on the Chukar Partridge as a model species, but he might not have made his discovery without a key piece of advice from the local rancher in Montana who was supplying him with birds... In an evolutionary context, WAIR takes on surprising explanatory powers. With one fell swoop, the Dials came up with a viable origin for the flapping flight stroke of birds (something gliding animals don't do and thus a shortcoming of the tree-down theory) and an aerodynamic function for half-formed wings (one of the main drawbacks to the ground-up hypothesis). 21 Which choice best reflects the overall sequence of events in the passage? A) An experiment is proposed but proves unworkable; a less ambitious experiment is attempted, and it yields data that give rise to a new set of questions. B) A new discovery leads to reconsideration of a theory; a classic study is adapted, and the results are summarized. C) An anomaly is observed and simulated experimentally; the results are compared with previous findings, and a novel hypothesis is proposed. D) An unexpected finding arises during the early phase of a study; the study is modified in response to this finding, and the results are interpreted and evaluated.

A) Lines 60-63 (Part of this is about principles. Some will argue that space's "magnificent desolation" is not ours to despoil, just as they argue that our own planet's poles should remain pristine) B) Lines 74-76 (The resources that are valuable in orbit and beyond may be very different to those we prize on Earth. Q) C) Lines 81-83 (One speaker at last week's space-mining forum in Sydney, Australia, concluded with a plea that regulation should be avoided.) D) Lines 85-87 (Without consensus, claims will be disputed, investments risky, and the gains made insecure.)
