The importance of the relatively docile eland (antelope) in the diet of Middle Stone Age (MSA) people contrasted with the increased importance of aggressive wild pigs to Late Stone Age (LSA) people has been interpreted as an indication that MSA hunters were less
proficient than LSA hunters. This has been used to support the view that neurological changes dramatically increased the behavioral sophistication of anatomically modern humans. However, alternative hypotheses have not been sufficiently examined to warrant this interpretation. The possibility that economic motives drove prey selection must first be excluded. Since eland are very large but less dangerous to hunt than wild pigs, it is likely that they would be a favored prey animal whether or not hunting strategies were sophisticated enough to tackle more aggressive prey.

As I write, the Large Hadron Collider, the worid' s biggest atom-smasher at CERN in Geneva, has switched on with almost unprecedented media jamboree. Asked about the practical value of it all, Stephen Hawking has said that "modern society is based on advances in pure science that were not foreseen to have practical
applications." It's a common claim, and it subtly reinforces the hierarchy that Medawar identified: technology and engineering are the humble offspring of pure science, the casual cast-offs of a more elevated pursuit.
I don't believe that such pronouncements are intended to denigrate applied science as an intellectual activity; they merely speak into a culture in which that has already happened. Pure science undoubtedly does lead to applied spin-offs, but this is not the norm. Rather, most of our technology has come from explicit and
painstaking efforts to develop it. And this is simply a part of the scientific enterprise. A dividing line between pure and applied science makes no sense at all, running as it does in a convoluted path through disciplines, departments,even individual scientific papers and careers. Research aimed at applications fills the pages of
the leading journals in physics, chemistry, and the life and Earth sciences; curiosity-driven research with no real practical value is abundant in the “applied" literature of the materials, biotechnological, and engineering sciences. The fact that "pure" and "applied" science are useful and meaningful terms seduces us sometimes into thinking that they are real, absolute, and distinct categories.

Until recently, study of motor control in amphibian feeding was limited to a few model taxa (taxonomic groups), for example, toads (genus Bufo), frogs ( Rana), and salamanders(Ambystoma). Studies of these taxa suggested that amphibian feeding in general is highly stereotyped, that is, performed in much the same way every time, with little variation in the timing or extent of movements. However, recent studies of a great variety of salamanders, frogs, and caecilians (tropical amphibians) have revealed that the model taxa are probably exceptions among amphibians, and were unfortunate models on which to base generalizations about amphibian feeding. Indeed, Bufo is now known to be one of the most stereotyped amphibians in its feeding movements,and Ambysfoma lies at the low end of variation for salamanders.

Blues music speaks histories that, from the conventional perspective, originate in the experiences of African Americans. But invariably, the blues exceed rigid cultural boundaries. Ralph Ellison's definition of the blues suggests an expansive vista, limited only by a speaker's capacity to lyrically express an
"autobiographical chronicle of personal catastrophe." As an idiom, the blues record histories, yet Ellison' s definition privileges the personal and leaves uncertain the role of national histories, the stories that speak our collective experiences. Locating the collective histories in the personal has proved a pivotal problem for readers in the written use of the blues both in Ellison's fiction and in works by Toni Morrison, Gayl Jones, and others.

The passage suggests that which of the following is an accurate characterization of the blues as defined by Ralph Ellison?

Select the sentence in the passage that describes a particular alternative to the conventional perspective on the blues.

Many herbivorous insects utilize plant resources during small windows of development or during short periods when plants are of suitable quality. Such temporal associations have been documented in numerous systems, where temporal constraints limit insect abundance and affect insect feeding strategy. Classic studies of winter moths, for example, suggest that the synchrony of larvae with leaf emergence is a primary determinant of larval success. Because many insect-plant associations have a temporal component, they may be negatively affected by environmental changes; some scientists fear, for example, that global warming may decouple insect-plant synchrony Hellman, however, notes that the timing of insect-plant synchrony is affected by many factors, including insects behavioral and physiological ability to adapt to changing host plant quality and the availability of alternative host resources.

The large amount of methane in the atmosphere of Saturn's giant moon Titan puzzles astronomers. Because methane is converted into heavier hydrocarbons by the Sun's ultraviolet light, all the methane in Titan's atmosphere should, at the present conversion rate, have disappeared in a few million years, long ago in Titan's 4.5 billion years of existence. Something must be continuously feeding methane into Titan's atmosphere. One possibility is that the methane comes from volcanic eruptions, but unless the supply rate were somehow precisely calibrated at a moderate level, either the methane would have run out by now or excess methane would have started to accumulate as a liquid ocean on the Surface. However, data indicate that the atmosphere just above the surface is not humid, as would be expected above a pure methane ocean. A possible explanation was suggested by Lunine: when sunlight breaks down methane, the main product is ethane. Lunine noted that at Titan's surface temperature, ethane is also a liquid. A liquid mixture of methane and ethane would produce low Humidity. Such an ocean would slowly become richer in ethane while keeping the atmosphere supplied with methane.

According to the passage,a mixture of liquid ethane and liquid methane on Titan could account for which of the following?
