The macromolecule RNA is common to all living beings, and DNA, which is found in all organisms except some bacteria, is almost as ...............
Show Hint
- comprehensive
- fundamental
- inclusive
- universal
- significant
ubiquitous
The Correct Option is D
Solution and Explanation
Step 1: Understand the context.
The passage compares RNA, which is common to all living organisms, with DNA, which is also almost universal, excluding a few exceptions.
Step 2: Analyze the options.
- (A): “Comprehensive” is not fitting because it implies coverage of all aspects, which is not the intended meaning.
- (B): “Fundamental” doesn’t capture the idea of being universally present.
- (C): “Inclusive” is too weak to express universal presence.
- (D): “Universal” fits perfectly, meaning present everywhere.
- (E): “Significant” doesn’t work because it refers to importance, not presence.
- (F): “Ubiquitous” also fits as it implies being everywhere.
Step 3: Conclusion.
Both “universal” and “ubiquitous” fit well.

- In the 1970s, two debates engaged many scholars of early United States history. One focused on the status of women, primarily White women. Turning on the so-called golden age theory, which posited that during the eighteenth-century colonial era, American women enjoyed a brief period of high status relative to their English contemporaries and to nineteenth-century American women, this debate pitted scholars who believed women’s lives deteriorated after 1800 against those who thought women’s lives had been no better before 1800. At issue were the causes of women’s subordination: were these causes already in place when the English first settled North America or did they emerge with the rise of nineteenth-century industrial capitalism?
The second debate, the so-called origins debate, concerned the emergence of racial slavery in the southern colonies: was slavery the inevitable result of the deep-rooted racial prejudice of early British colonists or did racial prejudice arise only after these planters instituted slave labor?
Although these debates are parallel in some respects, key differences distinguished them. Whereas the debate over women’s status revolved around implicit comparisons of colonial women to their counterparts in the antebellum period (1800--1860), thus inviting comment from scholars of both historical periods, the origins debate was primarily confined to a discussion about slavery in colonial America. Second, in contrast to the newness of the debate over women’s status and its continued currency throughout the early 1980s, the debate over race and slavery, begun in the 1950s, had lost some of its urgency with the publication of Morgan’s American Slavery, American Freedom (1975), widely regarded as the last word on the subject.
Each debate also assumed a different relationship to the groups whose histories it concerned. In its heyday, the origins debate focused mainly on White attitudes toward Africans rather than on Africans themselves. With few exceptions, such as Wood’s Black Majority (1974) and Mullin’s Flight and Rebellion (1972), which were centrally concerned with enslaved African men, most works pertaining to the origins debate focused on the White architects, mostly male, of racial slavery. In contrast, although women’s historians were interested in the institutions and ideologies contributing to women’s subordination, they were equally concerned with documenting women’s experiences. As in the origins debate, however, early scholarship on colonial women defined its historical constituency narrowly, women’s historians focusing mainly on affluent White women.
Over time, however, some initial differences between the approaches taken by scholars in the two fields faded. In the 1980s, historians of race and slavery in colonial America shifted their attention to enslaved people; interest in African American culture grew, thereby bringing enslaved women more prominently into view. Historians of early American women moved in similar directions during the decade and began to consider the effect of racial difference on women’s experience.- GRE - 2025

- The most plausible justification for higher taxes on automobile fuel is that fuel consumption harms the environment and thus adds to the costs of traffic congestion. But the fact that burning fuel creates these “negative externalities” does not imply that no tax on fuel could ever be too high. Economics is precise about the tax that should, in principle, be levied to deal with negative externalities:
the tax on a liter of fuel should be equal to the harm caused by using a liter of fuel.
If the tax is more than that, its costs (including the inconvenience to those who would rather have used their cars) will exceed its benefits (including any reduction in congestion and pollution).- GRE - 2025

- Objectively, of course, the various ecosystems that sustain life on the planet proceed independently of human agency, just as they operated before the hectic ascendancy of Homo sapiens. But it is also true that it is difficult to think of a single such system that has not, for better or worse, been substantially modified by human culture. Nor is this simply the work of the industrial centuries. It has been happening since the days of ancient Mesopotamia. It is coeval with the origins of writing, and has occurred throughout our social existence. And it is this irreversibly modified world, from the polar caps to the equatorial forests, that is all the nature we have.
