OG2022 Traveler: Southern Airways has a far worse safety record than Air Dacentaria over the past few years, in terms of both the frequency of accidents and the severity of accidents. Therefore, although Air Dacentaria is slightly more expensive, I will choose it over Southern Airways for my flight from Pederton to Dacenta, since it is worth paying extra to have a safer flight. Which of the following, if true, casts the most serious doubt on the traveler's argument?

OG12 OG15 OG16 OG17 OG18 Physician: The hormone melatonin has shown promise as a medication for sleep disorders when taken in synthesized form. Because the long-term side effects of synthetic melatonin are unknown, however, I cannot recommend its use at this time. Patient: Your position is inconsistent with your usual practice. You prescribe many medications that you know have serious side effects, so concern about side effects cannot be the real reason you will not prescribe melatonin.The patient's argument is flawed because it fails to consider that

Arrellan politician: An external company audits the finances of every county in Arrell. However, a problem is discovered in only one out of every 100 audits. Although those problems are often severe, they are detectable by other means, and because of the high costs of maintaining the contract with the auditing company, the contract should be terminated.

Consultant: I disagree. The threat of being audited makes many county governments less likely to distort their budget numbers.

Agricultural expert: A new type of fertilizer, SynthaGro, promises to increase yields for corn farmers. Because the long-term costs of using it are unknown, however, I do not recommend its use at this time.

Corn Farmer: Your position is inconsistent with your usual course of action. You recommend many products that have substantial costs to farmers, so cost cannot be the real reason you do not recommend SynthaGro.

The corn farmer’s argument is flawed because it fails to consider that

At the peak of tulip mania in Holland, in March 1637, some single tulip bulbs sold for more than 10 times the annual income of a skilled craftsman. It is generally considered the first recorded speculative bubble. The term "tulip mania" is now often used metaphorically to refer to any large economic bubble (when asset prices deviate from intrinsic values). The event was popularized in 1841 by British journalist Charles Mackay. According to Mackay, at one point 12 acres of land were offered for a <i style="font-style: italic;">Semper Augustusi> bulb. Mackay claims that many such investors were ruined by the fall in prices, and Dutch commerce suffered a severe shock. Some modern scholars, however, feel that the mania was not quite as extraordinary as Mackay described. Some even argue that not enough price data remain, historically, to represent an all out tulip bulb bubble. In her 2007 scholarly analysis <i style="font-style: italic;">Tulipmaniai>, Anne Goldgar states that the phenomenon was limited to "a fairly small group," and that most accounts from the period are based on a few contemporary pieces of propaganda. While Mackay's account held that a wide array of society was involved in the tulip trade, Goldgar's study of archived contracts found that even at its peak the trade in tulips was conducted almost exclusively by merchants and skilled craftsmen who were wealthy, but not by members of the nobility. Thus, any economic fallout from the bubble was very limited. Goldgar, who identified many prominent buyers and sellers in the market, found fewer than half a dozen who experienced financial troubles in the time period, and even of these cases it is not clear that tulips were to blame. This is not altogether surprising. Although prices had risen, money had not exchanged hands between buyers and sellers. Thus profits were never realized for sellers; unless sellers had made other purchases on credit in expectation of the profits, the collapse in prices did not cause anyone to lose money. There is no dispute that prices for tulip bulb contracts rose and then fell in 1636–37, but even a dramatic rise and fall in prices does not necessarily mean that an economic or speculative bubble developed and then burst. For tulip mania to have qualified as an economic bubble, the price of tulip bulbs would need to have become unhinged from the intrinsic value of the bulbs. Modern economists have advanced several possible reasons for why the rise and fall in prices may not have constituted a bubble. For one, the increases of the 1630s corresponded with a lull in the Thirty Years' War, which occurred between 1618 and 1648. Hence market prices were responding rationally to a rise in demand. However, the fall in prices was faster and more dramatic than the rise, and did not result from a sudden resurgence in the war.
OG12 OG15 OG16 OG17 OG18 Thyrian lawmaker: Thyria's Cheese Importation Board inspects all cheese shipments to Thyria and rejects shipments not meeting specifi ed standards. Yet only 1 percent is ever rejected. Therefore, since the health consequences and associated economic costs of not rejecting that 1 percent are negligible, whereas the board's operating costs are considerable, for economic reasons alone the board should be disbanded. Consultant: I disagree. The threat of having their shipments rejected deters many cheese exporters from shipping substandard product.The consultant responds to the lawmaker's argument by_____.

Schools expect textbooks to be a valuable source of information for students. My research suggests, however, that textbooks that address the place of Native Americans within the history of the United States distort history to suit a particular cultural value system. In some textbooks, for example, settlers are pictured as more humane, complex, skillful, and wise than Native American. In essence, textbooks stereotype and deprecate the numerous Native American cultures while reinforcing the attitude that the European conquest of the New World denotes the superiority of European cultures. Although textbooks evaluate Native American architecture, political systems, and homemaking, I contend that they do it from an ethnocentric, European perspective without recognizing that other perspectives are possible.One argument against my contention asserts that, by nature, textbooks are culturally biased and that I am simply underestimating children's ability to see through these biases. Some [hl:5]researchers[/hl:5] even claim that by the time students are in high school, they know they cannot take textbooks literally. Yet substantial evidence exists to the contrary. [hl:3]Two researchers, for example, have conducted studies that suggest that children's attitudes about particular culture are strongly influenced by the textbooks used in schools.[/hl:3] Given this, an ongoing, careful review of how school textbooks depict Native American is certainly warranted.
Archaeology as a profession faces two major problems. First, it is the poorest of the poor. Only paltry sums are available for excavating and even less is available for publishing the results and preserving the sites once excavated. Yet archaeologists deal with priceless objects every day. Second, there is the problem of illegal excavation, resulting in museum-quality pieces being sold to the highest bidder.I would like to make an outrageous suggestion that would at one stroke provide funds for archaeology and reduce the amount of illegal digging. I would propose that scientific archaeological expeditions and governmental authorities sell excavated artifacts on the open market. Such sales would provide substantial funds for the excavation and preservation of archaeological sites and the publication of results. At the same time, they would break the illegal excavator's grip on the market, thereby decreasing the inducement to engage in illegal activities.You might object that professionals excavate to acquire knowledge, not money. Moreover, ancient artifacts are part of our global cultural heritage, which should be available for all to appreciate, not sold to the highest bidder. I agree. Sell nothing that has unique artistic merit or scientific value. But, you might reply, everything that comes out of the ground has scientific value. Here we part company. Theoretically, you may be correct in claiming that every artifact has potential scientific value. Practically, you are wrong.I refer to the thousands of pottery vessels and ancient lamps that are essentially duplicates of one another. [hl:4]In one small excavation in Cyprus[/hl:4], archaeologists recently uncovered 2,000 virtually indistinguishable small jugs in a single courtyard. Even precious royal seal impressions known as l'melekh handles have been found in abundance —more than 4,000 examples so far.The basements of museums are simply not large enough to store the artifacts that are likely to be discovered in the future. There is not enough money even to catalog the finds; as a result, they cannot be found again and become as inaccessible as if they had never been discovered. Indeed, with the help of a computer, sold artifacts could be more accessible than are the pieces stored in bulging museum basements. Prior to sale, each could be photographed and the list of the purchasers could be maintained on the computer. A purchaser could even be required to agree to return the piece if it should become needed for scientific purposes.It would be unrealistic to suggest that illegal digging would stop if artifacts were sold on the open market. But the demand for the clandestine product would be substantially reduced. Who would want an unmarked pot when another was available whose provenance was known, and that was dated stratigraphically by the professional archaeologist who excavated it?

     The works of two nineteenth century thinkers promote conflicting theories of the locus of responsibility for the course of historical events. Thomas Carlyle, in his 1841 treatise <i>On Heroes, Hero-Worship, and the Heroic in Historyi>, places little emphasis on the events or conditions that produce major figures or the environments that allow them to rise to prominence. Instead, Carlyle posits that the extraordinary charisma, intelligence, wisdom, or political skill of individual “great” figures, invariably men, are the primary means by which social progress is effected. Herbert Spencer (1820–1903), though, writes not only that social environments are responsible for any great figures societies produce, but that Carlyle's approach is puerile and “unscientific” in the vein of many popular sociological works of the era. Although both thinkers promote a theory attempting to isolate the “mechanisms” of history vis-à-vis individual figures, only Spencer's has survived recent criticism largely intact. He emphasizes the lesser-understood contingencies of progress that comprise the immense majority of sociohistorical phenomena. He concludes that while major figures often take credit for the causal chain of significant events, the individuals themselves are less directly responsible for them than is commonly believed. This generality demonstrates how Spencer laid the foundation for twentieth-century historical scholarship, which holds to the belief that historical events, even those led by “heroes,” follow from multitudinous and sometimes untraceable social preconditions.
