1.CR
Country A currently relies on imports for its supply of wheat and soybeans. However, the government reports that if all of the country's unused arable land were dedicated to growing these crops, the nation could achieve self-sufficiency while also increasing the supply by 20% over current total demand. Consequently, even if Country A's population were to grow by 15%, the nation could still meet the increased demand by utilizing all of its unused arable land.
Which of the following statements, if true, would most weaken the government's claim?
(A) The demand for wheat and soybeans in Country A has been steadily increasing over the past decade due to population growth and changes in diet preferences.
(B) A significant portion of Country A's unused arable land is located in areas prone to frequent droughts and floods, making it unsuitable for reliable crop production.
(C) The government's report assumes that the yield per acre of wheat and soybeans on the unused arable land would be equal to the yield on land currently used for these crops.
(D) Dedicating all of the unused arable land to growing wheat and soybeans would require a significant investment in agricultural infrastructure, such as irrigation systems and storage facilities.
(E) Some of Country A's unused arable land is currently designated as protected wildlife habitats, and converting this land to agricultural use would require changes to environmental regulations.

A recent study aimed to investigate whether volunteers are more attentive to issues concerning themselves compared to non-volunteers. Researchers surveyed a group of volunteers and a control group of non-volunteers, asking them to recall details from a series of questions related to volunteering. The study found that volunteers were significantly better at remembering the questions compared to the control group. Based on these findings, the researchers concluded that volunteers are more focused on issues that directly relate to their own experiences and concerns.
Which of the following, if true, would most strongly support the researchers' conclusion?
(A) The questions used in the study were designed to be equally relevant and interesting to both volunteers and non-volunteers.
(B) Volunteers tend to have better memory skills than non-volunteers, possibly due to their regular engagement in mentally stimulating activities.
(C) The study also found that volunteers were more likely to express strong opinions about the importance of volunteering compared to non-volunteers.
(D) A significant portion of the questions in the survey directly related to the personal experiences and motivations of the volunteers.
(E) The researchers controlled for potential confounding variables, such as age and education level, when comparing the recall ability of volunteers and non-volunteers.

Tiny marks on the teeth of an ancient human ancestor known as the “Nutcracker Man” may upset current evolutionary understanding of early hominid diet.

Using high-powered microscopes, researchers looked at rough geometric shapes on the teeth of several Nutcracker Man specimens and determined that their structure alone was not enough to predict diet.

Peter Ungar, professor of anthropology at the University of Arkansas in Fayetteville, contends the finding shows evolutionary adaptation for eating may have been based on scarcity rather than on an animal’s regular diet.

“These findings totally run counter to what people have been saying for the last half a century,” says Ungar. “We have to sit back and re-evaluate what we once thought.”
Ungar and his colleagues, Frederick E. Grine of State University of New York at Stony Brook and Mark F. Teaford of Johns Hopkins University, Baltimore, Md., reported their findings last week in the Public Library of Science One, a peer-reviewed, international, online journal. The research was funded in part by the National Science Foundation.

The researchers examined the teeth of Paranthropus boisei, an ancient hominin that lived between 2.3 and 1.2 million years ago and is known popularly as the “Nutcracker Man” because it has the biggest, flattest cheek teeth and the thickest enamel of any known human ancestor.

“Ungar and colleagues’ work on Paranthropus boisei diet is extremely important,” says Joanna Lambert, physical anthropology program director at NSF. “Understanding what and how early hominins ate sheds light not only onto the feeding biology of our fossil ancestors, but also onto the very evolution of our own species.”

Scientists long have believed that P. boisei fed on nuts and seeds or roots and tubers found in the savannas throughout eastern Africa because the teeth, cranium and mandible appear to be built for chewing and crunching hard objects.
But Ungar points out that the teeth only suggest “what P. boisei could eat, but not necessarily what it did eat.”

Anthropologists have traditionally inferred the diet of ancient human ancestors by looking at the size and shape of the teeth and jaws. However, by using powerful microscopes to look at the patterns of wear on a tooth, scientists can get direct evidence of what the species actually ate.

Since food interacts with teeth, it leaves behind telltale signs that can be measured. Hard foods like nuts and seeds, for instance, lead to more complex tooth profiles, while tough foods like leaves lead to more parallel scratches.

Researchers compared dental microwear profiles of P. boisei to modern-day primates that eat different types of foods. P. boisei teeth were compared to those of the Old World Monkey species grey-cheeked mangabeys, and the New World Monkey species brown capuchin monkeys-both of these species consume mostly soft items but fall back on hard nuts or palm fronds.

Old World monkeys are found today in South and East Asia, the Middle East, Africa and Gibraltar at the southern tip of Spain. New World monkeys are found in tropical forest environments in southern Mexico, Central and South America.
P. boisei dental profiles also were compared to the New World mantled howling monkey and Old World silvered leaf monkey, which eat mostly leaves. Researchers also compared them to some of P. boisei’s more contemporary counterparts-Australopithecus africanus, which lived between 3.3 million and 2.3 million years ago, and Paranthropus robustus, which lived between 2 million and 1.5 million years ago.

The findings showed that P. boisei teeth had light wear, suggesting that none of the individuals ate extremely hard or tough foods in the days leading up to death. The pattern was more consistent with modern-day fruit-eating animals than with most modern-day primates.

“It looks more like they were eating Jell-O,” Ungar said.

This finding, while contradictory to previous speculation on the diet of P. boisei, is in line with a paradox documented in fish. Liem’s Paradox states that animals may actively avoid eating the very foods they have developed adaptations for when they can find other food sources.

It appears the paradox may hold true for P. boisei and for some modern-day primates as well.

“If you give a gorilla a choice of eating fruit or a leaf, it will take the fruit every time,” Ungar says. “But if you look at a gorilla’s skull, its sharp teeth are adapted to consuming tough leaves. They don’t eat the leaves unless they have to.”

Accordingly, the finding represents a fundamental shift in the way researchers look at the diets of early human ancestors.

“For many years, the perspective has been that the very large teeth and thick dental enamel of P. boisei were adaptations to consuming very hard food types year-round,” says Lambert. “Such specialization has historically been viewed as a potential cause for this fossil species’ extinction. The research team demonstrated that such generalizations require careful re-thinking, and that P. boisei was a more flexible feeder than has classically been viewed.”

“This challenges the fundamental assumptions of why such specializations occur in nature,” Ungar says. “It shows that animals can develop an extreme degree of specialization without the specialized object becoming a preferred resource.”

3.DI
The Austrian musical tradition, which reached its apogee during the Classical and Romantic eras, is often regarded as the apotheosis of Western art music. This tradition, which encompassed such luminaries as Haydn, Mozart, Beethoven, Schubert, and Brahms, was profoundly influenced by the humanistic and artistic ideals of the Italian Renaissance, which had permeated throughout Europe during the 16th and 17th centuries. The Italian Renaissance, with its emphasis on individualism, emotional expressiveness, and the revival of classical learning, had a seminal impact on the development of Austrian music, particularly in the realms of opera, sacred music, and instrumental music.

One of the key figures in the dissemination of Italian musical styles to Austria was the composer and theorist Johann Joseph Fux (1660-1741), who studied in Italy and later served as Kapellmeister at the Habsburg court in Vienna. Fux's magnum opus, Gradus ad Parnassum (1725), which codified the principles of Renaissance polyphony and counterpoint, became a seminal textbook for composers well into the 19th century, and was assiduously studied by such masters as Mozart and Beethoven. Fux's treatise, which emphasized the importance of imitating Renaissance models and the use of complex contrapuntal techniques, had a profound influence on the development of Austrian sacred music, particularly in the works of Mozart and his contemporaries.

The influence of Italian Renaissance humanism can also be discerned in the development of the opera, which originated in Florence in the late 16th century and rapidly proliferated throughout Europe. The earliest operas, such as Jacopo Peri's Dafne (1598) and Claudio Monteverdi's Orfeo (1607), sought to resurrect the ancient Greek ideal of music as a conduit for dramatic expression, and featured a new style of solo singing known as monody, which emphasized lucid declamation of the text and emotional expressiveness. This new operatic style, which represented a marked departure from the polyphonic complexity of Renaissance music, had a profound impact on the development of Austrian opera, particularly in the works of Mozart and his librettist, Lorenzo Da Ponte.

Mozart's operas, which amalgamate Italian bel canto singing with German theatrical traditions and Enlightenment ideals, are renowned for their psychological depth, musical sophistication, and subtle interplay between music and drama. Works such as The Marriage of Figaro (1786), Don Giovanni (1787), and Così fan tutte (1790) exemplify Mozart's mastery of the operatic form, and his ability to create complex, multi-dimensional characters through music. Mozart's operas also reflect the influence of Enlightenment ideals, particularly in their emphasis on reason, individuality, and social critique, as well as their exploration of themes such as class struggle, gender roles, and the tension between love and duty.

The influence of Italian Renaissance humanism can also be discerned in the instrumental music of the Classical and Romantic eras, which emphasized emotional expressiveness, technical virtuosity, and a sense of individual subjectivity. This is particularly evident in the works of Beethoven, whose symphonies, sonatas, and string quartets are often perceived as the embodiment of Romantic individualism and heroism. Beethoven's music, which represents a bridge between the Classical and Romantic eras, reflects the influence of Renaissance humanism in its emphasis on personal expression, innovation, and the breaking of traditional forms. Beethoven's late works, in particular, such as the Ninth Symphony and the late string quartets, are characterized by a sense of transcendence and spiritual striving that reflects the Romantic ideal of the artist as a visionary and prophet.

In conclusion, the Austrian musical tradition, which reached its zenith during the Classical and Romantic eras, was profoundly shaped by the humanistic and artistic ideals of the Italian Renaissance. From the theoretical treatises of Johann Joseph Fux to the operas of Mozart and the instrumental works of Beethoven, the influence of Italian Renaissance humanism can be discerned in the emphasis on emotional expressiveness, technical virtuosity, and individual subjectivity that characterizes the greatest works of Austrian art music. This tradition, which represents a unique synthesis of Italian, German, and Austrian cultural influences, had a profound impact on the development of Western art music as a whole.

The Austrian musical tradition not only absorbed and transformed the humanistic ideals of the Italian Renaissance but also served as a conduit for the dissemination of these ideals throughout Europe. The works of Haydn, Mozart, Beethoven, Schubert, and Brahms, which are celebrated for their formal perfection, emotional depth, and technical brilliance, continue to inspire and influence composers, performers, and music lovers around the world. The enduring legacy of the Austrian musical tradition is a testament to the power of music to transcend cultural and historical boundaries, and to express the deepest aspirations and emotions of the human spirit.

In a broader sense, the Austrian musical tradition can be seen as a microcosm of the larger cultural and intellectual ferment that characterized Europe during the Classical and Romantic eras. The ideals of the Enlightenment, with its emphasis on reason, individual liberty, and the pursuit of knowledge, found expression not only in the works of philosophers and scientists but also in the music of composers such as Mozart and Beethoven. At the same time, the Romantic movement, with its celebration of emotion, imagination, and the sublime, found its most powerful expression in the music of Schubert, Brahms, and other Austrian composers.

The Austrian musical tradition thus represents a unique confluence of cultural and historical forces, a synthesis of the humanistic ideals of the Italian Renaissance, the rational spirit of the Enlightenment, and the emotional intensity of the Romantic movement. It is a tradition that continues to resonate with us today, reminding us of the enduring power of music to express the deepest truths of the human experience, and to unite us across the boundaries of time, space, and culture.
