Most of the studies of the effect of aging on short-term memory have led researchers to conclude that younger adults perform short-term-memory tasks better than people over the age of 65. But these studies were all conducted in afternoon sessions. In a recent study conducted both in morning and in afternoon sessions. the older participants performed much better in morning sessions than in afternoon sessions. The younger participants did not, however, perform any better in the morning.
The statements given are structured to lead to which of the following conclusions

Given that ants and aphids are both abundant insect groups that often share the same habitats, that aphids excrete energy-rich honeydew, and that ants aggressively defend resources, it is difficult to understand why so few species of aphid have evolved a close relationship with ants. For example, only a quarter of the aphid species in the Rocky Mountain region are attended by ants, and in Central Europe, about one third are obligate myrmecophile [animals that closely associate with ants]. More than a dozen hypotheses have been proposed to account for the variability in aphid-ant relationships and the low proportion of attended species. First among them is the plant permissive hypothesis, which suggests that host-plant quality plays a critical role in determining the attractiveness of aphids for ants. Both variation in the quality of different hosts or different parts of the same host plant may affect the quality of honeydew, which is either more or less attractive to ants. However, this hypothesis ignores the fact that several species of aphids may feed on the same host plant or even plant organ but have very different degrees of associations with ants and assumes that the quality of phloem sap determines that of the honeydew. Recent studies have found that feeding on woody plant parts is positively associated with ant attendance, whereas mobility, feeding in isolation, and having winged adults are negatively associated with ant attendance.

If the plant permissive hypothesis is correct, it can be inferred from information presented in the passage that
Astronomers can measure any given star's radial velocity by examining its spectrum-light spread out into its constituent wavelengths. If an object is moving toward us,its spectral lines shift to shorter wavelengths; if it's moving away, the lines swing to longer wavelengths. The higher the velocity, the greater the shift. Although this sort of spectral analysis is straightforward for nearby stars. it becomes far more difficult for distant stars in the Milky Ways outer halo. Even large telescopes can't gather enough of the light. For this reason, astronomer Ulrich Heber conjectures that there are probably several low-mass hypervelocity stars yet to be discovered. Although these diminutive objects live longer than B type stars, which are extremely luminous and blue,they radiate much less light.
Despite winning several prestigious literary awards of the day, when it first appeared, Alice Walker`s The Color Purple generated critical unease over puzzling aspects of its compositions. In what, as one reviewer put it, was "clearly intended to be a realistic novel," many reviewers perceived violations of the conventions of the realistic novel form, pointing out variously that late in the book, the narrator protagonist Celie and her friends are propelled toward a happy ending with more velocity than credibility, that the letters from Nettie to her sister Celie intrude into the middle of the main action with little motivation or warrant, and that the device of Celie`s letters to God is especially unrealistic in as much as it forgoes the concretizing details that traditionally have given the epistolary novel (that is, a novel composed of letters) its peculiar verisimilitude: the ruses to enable mailing letters, the cache, and especially the letters received in return.

Indeed, the violations of realistic convention are so flagrant that they might well call into question whether The Color of Purple is indeed intended to be a realistic novel, especially since there are indications that at least some of those aspects of the novel regarded by viewers as puzzling may constitutes its links to modes of writing other than Anglo-European nineteenth-century realism. For example, Henry Louis Gates, Jr., has recently located the letters to God within an African American tradition deriving from slave narrative, a tradition in which the act of writing is linked to a powerful deity who "speaks" through scripture and bestows literacy as an act of grace. For Gates, the concern with finding a voice, which he sees as the defining feature of African American literature, links Celie`s letters with certain narrative aspects of Zora Neale Hurston`s 1937 novel Their Eyes Were Watching God, the acknowledged predecessor of The Color Purple.

Gates`s paradigm suggests how misleading it may be to assume that mainstream realist criteria are appropriate for evaluating The Color Purple. But in his preoccupation with voice as a primary element unifying both the speaking subject and the text as a whole Gates does not elucidate many of the more conventional structural features of Walker`s novel. For instance, while the letters from Nettie clearly illustrate Nettie`s acquisition of her own voice, Gates`s focus on "voice" sheds little light on the place that these letters occupy in the narrative or on why the plot takes this sudden jump into geographically and culturally removed surroundings. What is needed is an evaluative paradigm that, rather than obscuring such startling structural features (which may actually be explicitly intended to undermine traditional Anglo-European novelistic conventions), confronts them, thus illuminating the deliberately provocative ways in which The Color Purple departs from the traditional models to which it has been compared.

Crows, herring gulls, and sparrows all live on the island of Firsten. Crows feed on sparrow eggs and the therefore pose a threat to the sparrow population. Although gulls are not nearly as good at finding sparrow nests as crows are, sparrows typically also lose some eggs to gull predation. Nevertheless, sparrows that nest near gull nests tend to lose fewer eggs to predators than sparrows nesting far away from gull nests, since ________ .
Which of the following most logically completes the argument?
Many scholarly discussions of novelist Willa Cather(1873-1947) debate whether Cather belongs more to the nineteenth-century realist tradition or to the modernist revolution of the early twentieth century. While Cather's preoccupation with nineteenth-century agrarian culture has won the respect of readers and critics, her distrust of modernity left her with a historically unstable position in the modernist canon. Resistance to the changes wrought by the twentieth century,of course, does not necessarily disqualify one from the "modernist" label. The impulse to reconnect with more primitive, earlier times is a hallmark of modernist aesthetics shaping the search for meaning in a fragmented, disenchanted mechanized world. Yet more often than not. [literary critic]

Phyllis Rose explains the early twentieth-century atmosphere of experimentation and "making it new" and an attendant critical discourse that "valued complexity, ambiguity, even obscurity" resulted in Cather's labeling as "naively traditional" and essentially nostalgic and elegiac. "In effect, in modernist studies she has been treated as a romantic regional writer. Unconcerned with the international terrain so integral to modern thinking-at least until scholars, in the 1980s and 1990s, began reevaluating the historical record, demonstrating her innovative departures from nineteenth-century fiction including antiheroism, gender-bending, episodic narrative, antirealism, simple prose. emphasis on memory and time, and the exploration of immigration, empire, and race. Today it is not uncommon to encounter critics announcing Cather`s newfound canonical status as a modernist--indicated most clearly by her inclusion in works such as The Cambridge Companion to American Modernism published in 2005.

Much of ecological theory consists of models that are so highly idealized that they are of little real-world predictive value. In addition, many of the parameters used in models such as birth and death rates are exceedingly difficult to estimate accurately in the field. Consequently, ecological theory is rarely directly relevant to the practice of conservation biology. One notable exception is MacArthur's theory of island biogeography, which predicts the species richness of an island on the basis of its size and degree of isolation. This theory could provide important insights into nature preserves, which can be analogous to islands, often consisting of relatively undisturbed ecosystems surrounded by biologically distinct areas.
