In the 1860s, the German philologist Lazarus Geiger proposed that the subdivision of color always follows the same hierarchy. The simplest color lexicons (such as the DugermDani language of New Guinea) distinguish only black/dark and white/light. The next color to be given a separate word by cultures is always centered on the red part of the visible spectrum. Then, according to Geiger, societies will adopt a word corresponding to yellow, then green, then blue. Lazarus's color hierarchy was forgotten until restated in almost the same form in 1969 by Brent Berlin, an anthropologist, and Paul Kay, a linguist, when it was hailed as a major discovery in modern linguistics. It showed a universal regularity underlying the apparently arbitrary way language is used to describe the world. Berlin and Kay's hypothesis has since fallen in and out of favor, and certainly there are exceptions to the scheme they proposed. But the fundamental color hierarchy, at least in the early stages (black/white, red, yellow/green, blue) remains generally accepted. The problem is that no one could explain why this ordering of color exists. Why, for example, does the blue of sky and sea, or the green of foliage, not occur as a word before the far less common red? There are several schools of thought about how colors get named. “Nativists,” who include Berlin and Kay argue that the way in which we attach words to concepts is innately determined by how we perceive the world. In this view our perceptual apparatus has evolved to ensure that we make “sensible”—that is, useful—choices of what to label with distinct words: we are hardwired for practical forms of language. “Empiricists,” in contrast, argue that we don't need this innate programming, just the capacity to learn the conventional (but arbitrary) labels for things we can perceive. In both cases, the categories of things to name are deemed “obvious”: language just labels them. But the conclusions of Loreto and colleagues fit with a third possibility: the “culturist” view, which says that shared communication is needed to help organize category formation, so that categories and language co-evolve in an interaction between biological predisposition and culture. In other words, the starting point for color terms is not some inevitably distinct block of the spectrum, but neither do we just divide up the spectrum in some arbitrary fashion, because the human eye has different sensitivity to different parts of the spectrum. Given this, we have to arrive at some consensus, not just on which label to use, but on what is being labeled.

A technology company plans to develop a prototype laptop that uses iris scanners that can distinguish one user from another. The inventor of this laptop claims that it will reduce insurance and security costs at offices, as only authorized users will be able to turn on the laptop, making it a less appealing target for thieves.Which of the following, if true, most supports the company's implementing its plan to develop the prototype?

The following is an excerpt from a campaign speech. Senator Baker: My opponent, Candidate Rothmore, has called for increased taxes to fund programs that help the long-term unemployed of the state. Such action would address an immediate symptom for a select group, without doing much to address the overall problems we all face. Only through lowering taxes can we stimulate the growth of small businesses, which will revitalize the state's whole economy. That, in turn, will result in greater prosperity and in more jobs, including jobs for those who have been unemployed for a while. Through lowering taxes, everyone wins, and those currently unemployed get the best help the economy can provide --- a real job. In the argument, the two portions in boldface play which of the following roles?

Last week, an investigative journalist published an exposé in the newspaper, demonstrating that many of the shoes sold in a certain department store in California were made overseas in sweatshops that are alleged to use child labor. This week, the department store experienced a drop in shoe sales, after twelve weeks of robust sales of shoes. The management team of the department store maintains that the unfavorable article in the newspaper last week had nothing to do with their drop in shoe sales this week.
Which of the following, if true, most strongly supports the management team's position?

A certain city has had many vacant homes in the downtown neighborhoods. The city loses significant tax revenue each year because those houses stand unoccupied. The city felt that the fear of crime was keeping professionals from moving into these houses. Over 80% of the city's professional work force live outside of the city, in nearby suburbs, and commute daily. Plan: Five years ago, the city tripled the size of the municipal police force, increasing patrols throughout the city. All studies have confirmed that crime has dropped substantially. Result: the vacancy rate in these single-family houses has not changed substantially in five years.
Further information: Almost all of the vacant houses are in excellent condition, ready for occupancy. The city supports a number of high-paying professional jobs, and the state economy has been booming over the past five years.
In light of the further information, which of the following, if true, does most to explain the result that followed the implementation of the plan?

Operations at the Green Hills Gold Mine are continuously releasing mercury into the headwaters of the Apache River, and most fish in the Apache River now have mercury levels at or above the legal limit for human consumption. With the price of gold rising, forcing more and more mining at Green Hills, there seems no hope for food fishing along the Apache River.Which of the following plans, if feasible, would allow the state to assist the food fishing industries along the Apache?

In 1883, the Indonesian island Krakatoa, home to a massive volcano, seemingly disappeared overnight as an eruption rent the entire island apart, catapulting rock and debris into the atmosphere. For the next few years, as ash circled the entire globe, the average world temperature dropped by several degrees Fahrenheit. Therefore, an eruption of similar power in terms of the amount of debris ejected into the atmosphere will likely cause the average temperature around the world to drop by several degrees.Which of the following, if true, best challenges the main claim of the argument?

The CFO attributes our increased sales last year to the new markets in Eastern Europe. Nevertheless, a careful study of our revenue reveals a boom of sales in Southeast Asia, while the markets in Eastern Europe, after an early surge, settled at levels much lower than expected. After all, in Eastern Europe, our firm has fierce competition from both German and Russian exports, some of which offer exceptionally high quality at low cost. By contrast, no producers in this sector operate to the East of Turkey, and our firm is the only one in our sector with significant inroads into India, Thailand, Vietnam, and Taiwan. Current plans call for expansion into Eastern Europe, but the Southeast Asian markets hold much more promise. In the argument given, the two portions in boldface play which of the following roles?
