The highly dispersed nature of Panzaleo pottery throughout present-day Ecuador has led archaeologists to speculate about the pottery's origins and significance. Jijon y Caamano attributed the pottery's distribution to trade, and based on the large quantities of pottery recovered in the Ambato-Latacunga region of the central Ecuadorian highlands, he proposed that region as the probable locus of production. However. Porras suggests that inhabitants of the subtropical eastern Andean slopes, or montafta, were the original producers of Panzaleo. Porras: theory involves the forced migration of the montaria population from their homeland in the Quijos River valley into the Ecuadorian highlands. The gradual exodus and ensuing dispersal of the makers of this ware could account for the diffuse distribution of the materials.
The passage cites evidence supporting which of the following hypotheses?
The following appeared in a letter from the owner of the Sunnyside Towers apartment complex to its manager.
"Last week, all the showerheads in the first three buildings of the Sunnyside Towers complex were modified to restrict maximum water flow to one-third of what it used to be. Although actual readings of water usage before and after the adjustment are not yet available, the change will obviously result in a considerable savings for Sunnyside Corporation, since the corporation must pay for water each month. Except for a few complaints about low water pressure, no problems with showers have been reported since the adjustment. Clearly, modifying showerheads to restrict water flow throughout all twelve buildings in the Sunnyside Towers complex will increase our profits further."

The following appeared in a memo from the president of Bower Builders, a company that constructs new homes.
"A nationwide survey reveals that the two most-desired home features are a large family room and a large, well-appointed kitchen. A number of homes in our area built by our competitor Domus Construction have such features and have sold much faster and at significantly higher prices than the national average. To boost sales and profits, we should increase the size of the family rooms and kitchens in all the homes we build and should make state-of-the-art kitchens a standard feature. Moreover, our larger family rooms and kitchens can come at the expense of the dining room, since many of our recent buyers say they do not need a separate dining room for family meals."

The following appeared as a letter to the editor from the owner of a skate shop in Central Plaza.
"Two years ago the city council voted to prohibit skateboarding in Central Plaza. They claimed that skateboard users were responsible for litter and vandalism that were keeping other visitors from coming to the plaza. In the past two years, however, there has been only a small increase in the number of visitors to Central Plaza. and litter and vandalism are still problematic. Skateboarding is permitted in Monroe Park, however, and there is no problem with litter or vandalism there. In order to restore Central Plaza to its former glory, then, we recommend that the city lift its prohibition on skateboarding in the plaza."

Like paleontologists who interpret timescales from fossil evidence, we infer the history of star formation in the Milks' Way galaxy from the heavy-element composition of its stars. According to the big bang theory of the origin of the universe, the first gas clouds—and the first generation of stars formed from them—were composed of pure hydrogen and helium; most heavier elements— iron and calcium, for example—came later, created by explosions of supernovas, massive stars in their death thaws. Loaded with heavy elements, material ejected from supernovas enriched the interstellar gas clouds from which the next generation of stars formed, the level of heavy elements increasing with succeeding generations. Because most stars live for many billions of years and because the Milky Way is thus composed of multiple stellar generations, comparing the number of stars of low heavy-element abundance with those of high heavy-element abundance enables astronomers to untangle the history of star formation in the Milky Way.
The passage implies that if a star contains calcium, then the
In the brushland of Klanos Island, seeds of the plant Emmenan the penduliflora normally stay dormant for years and germinate only after a brushfire. The resulting plants quickly mature, produce seed, and then die. It is the nitrogen dioxide in (he smoke that induces the seeds lo germinate. Because automobiles are being introduced on Klanos. and their exhaust contains nitrogen dioxide, the plants will probably be seen throughout Klanos every year.

Discussions of the collapse of the lowland Maya are not new. However, it might be better to say that Maya civilization as a whole did not collapse, although many zones did experience profound change. Because societies are not bounded, unitary entities. collapses are rarely total, and continuity is a normal pan of collapse At the end of the Classic period [200 900 C.E.]. the institution of divine kingship and many of the well-known markers of elite culture such as carved stelae [slabs erected for funerals or commemorative purposes] and hieroglyphic polychromes [multicolored artistic pottery) ended, but Maya civilization continued in modified form with many important features intact (e.g.. literacy, war. art. the production of fine ceramics). In some cases large buildings were constructed in the Postclassic period [900-1512 C.E.], but the transition to the Early Postclassic [900-1200 CXj era is distinctive for a decrease in elite goods and contexts. The variability in artifact changes during the Terminal Classic [800-900 C.E.] and into the Postclassic. even within artifact classes (e.g.. fine versus unslipped ceramics), suggests weaker centralized control than during the Classic period. Site abandonments in the Terminal Classic indicate the collapse of the functional ability of Maya states, but sites that survived show that Maya civilization continued albeit without divine kingship and much of the spectacle around it.
The passage suggests which of the following about Maya living after the Terminal Classic in "sites that survived"?
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?

One difficulty in convincing early scientists that craters fanned as a result of impacts from space is that most craters are circular. Impacts could come in at any angle, and experiments firing projectiles in the laboratory show that low-angle impacts lead to elliptical craters, not circular ones. Furthermore, while there was rarely evidence of any impacting object, there was often silicate melt around, suggesting that craters were caused by volcanic processes. The breakthrough in understanding crater origin was the recognition that the shock caused by the impacting object—not the object itself—creates a circular crater some twenty Times larger than the diameter of the impactor. The impact also generates enough heat to largely vaporize the impactor and melt the native rock.
Based on the passage, it can be inferred that research focused on "a classical case of bilingualism"
