An alarming number of Mediterranean monk seals, an endangered species, have recently died. Postmortem analysis showed the presence of an as yet unidentified virus, as well as evidence of a know bacterial toxin. Seawater samples from the area where the seals died did contain unusually high concentrations of the toxic bacterium. Therefore, although both viruses and bacterial toxins can kill seals, it is more likely that these deaths were the result of the bacterial toxin.
Which of the following, if true, provides additional evidence to support the conclusion?
A. Viruses are much more difficult to identify in postmortem analysis than bacteria are.
B. Mediterranean monk seals are the only species of seal in the area where the bacterium was found.
C. The bacterium is almost always present in the water in at least small concentrations.
D. Nearly all the recent deaths were among adult seals, but young seals are far more susceptible to viruses than are adult seals.
E. Several years ago, a large number of monk seals died in the same area as a result of exposure to a different bacterial toxin.
Before feminist literary criticism emerged in the 1970s, the nineteenth-century United States writer Fanny Fern was regarded by most critics (when considered at all) as a prototype of weepy sentimentalism—a pious, insipid icon of conventional American culture. Feminist reclamations of Fern, by contrast, emphasize her nonsentimental qualities, particularly her sharply humorous social criticism. Most feminist scholars find it difficult to reconcile Fern’s sardonic social critiques with her effusive celebrations of many conventional values.Attempting to resolve this contradiction, Harris concludes that Fern employed flowery rhetoric strategically to disguise her subversive goals beneath apparent conventionality. However, Tompkins proposes an alternative view of sentimentality itself, suggesting that sentimental writing could serve radical, rather than only conservative ends by swaying readers emotionally, moving them to embrace social change.
The history of the transmission of ancient Roman texts prior to invention of the printing press is reconstructed from evidence both internal and external to the texts themselves. Internal evidence is used to reconstruct the relationship of the surviving manuscripts of a Roman text to one another, as represented in a modern stemma codicum: a diagram depicting the genealogical relationship of surviving manuscripts and those the stemmas editor believes existed at one time. Stemma are scholar’s only road maps to textual connections based on internal evidence, but they may paint a distorted picture of reality because they diagram the relationships of only those manuscripts known or inferred today.
When studying shrimp feeding from hydro-thermal vents at the bottom of the ocean, biologists were surprised that the shrimps’ reproductive cycles followed seasonal patterns. Far beyond the reach of sunlight, and with food abundant around the vents all year round, why should such animals reproduce seasonally? The answer might involve their offspring, which in their larval form drift in the currents to colonize new vents. The larvae must feed during their trip, and their springtime release coincides with a peak in algae raining down from surface waters. So far, researchers have found no evidence of seasonal breeding among vent-dwelling species that provide their offspring with yolk to sustain them or among vent-dwelling species found in areas of the ocean with not seasonal algae blooms.
The manuscripts of the eight extant Latin tragedies identify the plays as the Marci Lucii Annei Senecae Tragoediae. Since nobody of that name is known, modern scholars believe the dramasto be the work of Lucius Annaeus Seneca the Younger, the well-known philosopher, orator and politician. Clearly the tragedies were written during Seneca’s lifetime: internal references to earlier poets, most notably Ovid, indicate that the dramas cannot have been composed prior to the second decade C.E., and the plays must have been written by 96C.E., when Quintilian quotes Medea, one of the tragedies.
Recent studies of ancient Maya water management have found that the urban architecture of some cities was used to divert rainfall runoff into gravity-fed systems of interconnected reservoirs. In the central and southern May Lowlands, this kind of water control was necessary to support large populations throughout the year due to the scarcity of perennial surface water and the seasonal availability of rainfall. Some scholars argue that the concentration of water within the urban core of these sites provided a centralized source of political authority for Maya elites based largely on controlled water access. Such an argument is plausible, however, it is less useful for understanding the sociopolitical implications of water use and control in other, water-rich parts of the Maya region.
Ralph Ellison was passionately interested in visual arts. He immersed himself in Harlem’s art scene in the 1930s, even apprenticing with sculptor Richmond Barthe for a time. Yet he was wary of projects aiming to provide a visual rendering of his novel Invisible Man. He reluctantly allowed Franklin Library to publish two illustrated versions of the novel but found the results disappointing and repeatedly rejected proposed film versions of the book. Despite his involvement in visual arts, Ellison insisted that only language could capture the complexity of American identity. This complexity consisted of the tension arising from the collision of the United States’ written ideals, as outlined in the founding documents, and the historical and contemporary experience molding the national consciousness.
Although vastly popular during its time, much nineteenth-century women’s fiction in the United States went unread by the twentieth-century educated elite, who were taught to ignore it as didactic. However, American literature has a tradition of didacticism going back to its Puritan roots, shifting over time from sermons and poetic transcripts into novels, which proved to be perfect vehicles for conveying social values. In the nineteenth century, critics reviled Poe for neglecting to conclude his stories with pithy moral tags, while Longfellow was canonized for his didactic verse. Although rhetorical changes favoring the anti-didactic can be detected as nineteenth-century American transformed itself into a secular society, it was twentieth-century criticism, which placed aesthetic value above everything else, that had no place in its doctrine for the didacticism of others.
Some archaeologists speculate that the Americas might have been initially colonized between 40,000 and 25,000 years ago. However, to support this theory it is necessary to explain the absence of generally accepted habitation sites for that time interval in what is now the United States. Australia, which has a smaller land area than the United States, has many such sites, supporting the generally accepted claim that the continent was colonized by humans at least 40,000 years ago. Australia is less densely populated (resulting in lower chances of discovering sites) and with its overall greater aridity would have presented conditions less favorable for hunter-gatherer occupation.
