This passage is excerpted from material published in 1997. Scientists have been puzzled by the seeming disparity between models of global warming based on greenhouse gas emissions and actual climatological data. In short, the world is not warming up as much as these models have predicted. In the early 1990s, Pat Michaels sought to explain this disparity, suggesting that sulfate emissions in industrial areas had a cooling effect, thus temporarily retarding global warming. Michaels later came to doubt this idea, however, pointing out that since most sulfate is emitted in the Northern Hemisphere, its cooling influence should be largely limited to that hemisphere. Yet, since 1987, warming in the Southern Hemisphere, which had been relatively intense, has virtually ceased, while warming in the north has accelerated. Thus, Michaels not only doubted the idea of sulfate cooling, but came to feel that global warming models themselves may be flawed. Ben Santer disagrees. Santer contends that, in general, global warming occurs more slowly in the south because this hemisphere is dominated by oceans, which warm more slowly than the landmasses that dominate the Northern Hemisphere. But, according to Santer, the situation remains complicated by sulfate cooling, which peaked in the north in the mid-twentieth century. It drastically slowed warming in the Northern Hemisphere, and warming in the Southern Hemisphere raced ahead . Since 1987, Santer argues, the greenhouse effect has reasserted itself, and the north has taken the lead. Thus, Santer disputes Michaels's claim that model predictions and observed data differ fundamentally.

Antonia Castañeda has utilized scholarship from women's studies and Mexican-American history to examine nineteenth-century literary portrayals of Mexican women. As Castañeda notes, scholars of women's history observe that in the United States, male novelists of the period—during which, according to these scholars, women's traditional economic role in home-based agriculture was threatened by the transition to a factory-based industrial economy— define women solely in their domestic roles of wife and mother. Castañeda finds that during the same period that saw non-Hispanic women being economically displaced by industrialization, Hispanic law in territorial California protected the economic position of “Californianas” (the Mexican women of the territory) by ensuring them property rights and inheritance rights equal to those of males. For Castañeda, the laws explain a stereotypical
plot created primarily by male, non-Hispanic novelists: the story of an ambitious non-Hispanic merchant or trader desirous of marrying an elite Californiana. These novels' favorable portrayal of such women is noteworthy, since Mexican-American historians have concluded that unflattering literary depictions of Mexicans were vital in rallying the United States
public's support for the Mexican-American War (1846–1848). The importance of economic alliances forged through marriages with Californianas explains this apparent contradiction. Because of their real- life economic significance, the Californianas were portrayed more favorably than were others of the same nationality.

In a certain learning experiment, each participant had three trials and was assigned, for each trial, a score of either –2, –1, 0, 1, or 2. The participant's final score consisted of the sum of the first trial score, 2 times the second trial score, and 3 times the third trial score. If Anne received scores of 1 and –1 for her first two trials, not necessarily in that order, which of the following could NOT be her final score?
