Origin, distribution, and habitat are included in the book for some but not all of the plants: offering this information for each species would have given readers a clearer appreciation of the differences between _________and introduced species.

The relevance of the literary personality—a writer's distinctive attitudes, concerns, and artistic choices—to the analysis of a literary work is being scrutinized by various schools of contemporary criticism. Deconstructionists view the literary personality, like the writer's biographical personality, as irrelevant. The proper focus of literary analysis, they argue, is a work's intertextuality (interrelationship with other texts), subtexts (unspoken, concealed. or repressed discourses), and metatexts (self-referential aspects), not a perception of a writer's verbal and aesthetic "fingerprints." New historicists also devalue the literary personality, since, in their emphasis on a work's historical context, they credit a writer with only those insights and ideas that were generally available when the writer lived. However, to readers interested in literary detective work—say scholars of classical (Greek and Roman) literature who wish to reconstruct damaged texts or deduce a work's authorship— the literary personality sometimes provides vital clues.

Which of the following does the author mention in the passage as a concern of (^constructionists?

The complex topic of whether bilingualism enhances cognitive functions beyond language, the so-called "bilingual advantage." is an intensely debated subject. Research results can be influenced by many variables, including the definition of bilingualisni itself. The previous focus on what was perceived to be a classical case of bilingualism (early, simultaneous acquisition of more than one language) has been largely replaced by a more inclusive definition. based on the ability to communicate rather than a perfect command. Indeed, improvement in cognitive functions has been reported after only one week of an intensive language course. Conversely, inactive bilinguals. who were early balanced bilinguals in their childhood but moved to an exclusive use of one language in later life, perform differently from active bilinguals and more like monolinguals.

Iii the context of the passage as a whole, the reference to "improvement in cognitive functions" primarily serves to

Female Australian Dunatothrips [small, sap-sucking insects] create tent-like structures on the surface of leaves to protect themselves and their eggs and larvae from desiccation in the arid Australian climate. Bono and Crespi compared survival and reproduction of thrips tliat founded structures alone with those in groups of two or more individuals. They found that although per capita egg production fell with increasing group size, foundresses were more likely to survive and lay eggs in groups than when alone. Several studies of other species of nest-building insects have concluded that foundress associations are beneficial to all parties. It is likely that the relative success of groups is at least in part accounted for by a reduction of energy use in the modification of a shared nest.

According to the passage. Bono and Crespi's findings showed that

Recent research has questioned the long-standing view of pearly mussels as exclusively suspension feeders (animals that strain suspended particles from water) that subsist on phytoplankton (mostly algae). Early studies of mussel feeding were based on analyses of gut contents, a method that has three weaknesses. First, material in mucus-bound gut contents is difficult to identify and quantify. Second, material found in the gut may pass undigested out of the mussel, not contributing to its nutrition. Finally, examination of gut contents offers limited insight into the mechanisms and behaviors by which mussels acquire food. Modem studies suggest that pearly mussels feed on more than just algae and may use other means than suspension feeding. Pedal feeding (sweeping up edible material with a muscular structure called the foot) has been observed in juvenile pearly mussels.

Besides the phytoplankton pearly mussels capture from the water column, their guts also contain small animals, protozoans, and detritus (nonliving particulate organic material). Recent studies show that mussels can capture and assimilate bacteria as well, a potentially important source of food in many fresh waters. Another potential source of food for mussels is dissolved organic matter. Early studies showing that pearly mussels could take up simple organic compounds were largely discounted because such labile (unstable) compounds are rarely abundant in nature. Nevertheless, recent work on other bivalves suggests that dissolved organic matter may be a significant source of nutrition.

Of this complex mix of materials that pearly mussels acquire, what is actually required and assimilated? Stable-isotope analyses of mussels taken from nature and of captive-reared mussels are beginning to offer some insight into this question. Nichols and Garling showed that pearly mussels in a small river were omnivorous, subsisting mainly on particles less than 2S micrometers in diameter, including algae, detritus, and bacteria. Bacterially derived carbon was apparently the primary source of soft-tissue carbon. However, bacteria alone cannot support mussel growth, because they lack the necessary long-chain fatty acids and sterols and are deficient in some amino acids. Bacteria may supplement other food resources, provide growth factors, or be the primary food In habitats such as headwater streams, where phytoplankton is scarce. Juvenile mussels have been most successfully reared m the laboratory on diets containing algae high in polyunsaturated fatty acids. Thus, it appears that the pearly mussel diet in nature may consist of algae, bacteria, detritus, and small animals and that at least some algae and bacteria may be required as a source of essential biochemicals.

The passage mentions which of the following as a factor that limits the information researchers can glean from analyzing gut contents?

The importance of the Bill of Rights in twentieth-century United States law and politics has led some historians to search for the "original meaning" of its most controversial clauses. This approach. known as "originalism." presumes that each right codified in the Bill of Rights had au independent history that can be studied in isolation from the histories of other rights, and its proponents ask how formulations of the Bill of Rights in 1791 reflected developments in specific areas of legal thinking at that time. Legal and constitutional historians, for example, have found originalism especially useful in the study of provisions of the Bill of Rights that were innovative by eighteenth-century standards, such as the Fourth Amendment's broadly termed protection against "unreasonable searches and seizures." Recent calls in the legal and political arena for a return to a "jurisprudence of original intention." however, have made it a matter of much more than purely scholarly interest when originalists insist that a clause's true meaning was fixed at the moment of its adoption, or maintain that only those rights explicitly mentioned in the United States Constitution deserve constitutional recognition and protection. These two claims seemingly lend support to the notion that an interpreter must apply fixed definitions of a fixed number of rights to contemporary issues, for the claims imply that the central problem of rights in the Revolutionary era was to precisely identity, enumerate, and define those rights that Americans felt were crucial to protecting their liberty.

Both claims, however, are questionable from the perspective of a strictly historical inquiry, however sensible they may seem from the vantage point of contemporary jurisprudence. Even though originalists are correct in claiming that the search for original meaning is inherently historical, historians would not normally seek.
