Magoosh SafeZone mosquito repellant has been shown in laboratory settings to be effective for twelve hours against the female anopheles mosquito, the only mosquito that transmits malaria. SafeZone, however, is not effective against mosquitoes that do not transmit malaria. The only instance in which SafeZone does not repel the female anopheles mosquito is when this mosquito can detect any ruptured blood vessels, a state that inevitably results whenever any kind of mosquito bites a person. Therefore, assuming one does not have any ruptured blood vessels on their skin before applying SafeZone, that person will not be able to catch malaria for up to twelve hours.Which of the following, if true, would argue most against the use of SafeZone in areas in which malaria is endemic?
Magoosh When a married couple has frequent emotionally satisfying conversations, they tend in overwhelming percentages to remain married throughout their lives. Queen Melinda and Prince Jonathan, Duke of Westphalia, have been married for over sixty years, so clearly they must have emotionally satisfying conversations all the time. This argument is most vulnerable to what criticism?
Fewer families lose their houses because of major disasters such as fire or flood than because of a wage earner's illness that results in death or disability. Yet, whereas most mortgage companies require borrowers to carry insurance to protect against major disasters, they do not require insurance to protect against the death or disability of a wage earner.Which of the following, if true, would contribute most to an explanation of the difference in insurance requirements?

In early civilizations, the development of early calendar systems—motivated most often by the desire to improve crop production—often coincided with the advancement of mathematics and astronomy. Granted, the practice of studying celestial bodies also gave rise to astrology and religion, which often had the effect of slowing the progress of the former two areas. Nevertheless, the inhibiting effect of astrology and religion is unlikely to have a lasting impact on mathematical and astronomical progress. Therefore, in all likelihood, the advancement of agrarian science, by motivating the development of measuring seasons and time, led to improved understanding of mathematics and astronomy in early civilizations.

In the argument given, the two boldfaced portions play which of the following roles?
GWD PREP08 Test 2 As a large corporation in a small country, Hachnut wants its managers to have international experience, so each year it sponsors management education abroad for its management trainees. Hachnut has found, however, that the attrition rate of graduates from this program is very high, with many of them leaving Hachnut to join competing firms soon after completing the program. Hachnut does use performance during the program as a criterion in deciding among candidates for management positions, but both this function and the goal of providing international experience could be achieved in other ways. Therefore, if the attrition problem cannot be successfully addressed, Hachnut should discontinue the sponsorship program.In the argument given, the two boldfaced portions play which of the following roles?
GWD Scientists typically do their most creative work before the age of forty. It is commonly thought that this happens because aging by itself brings about a loss of creative capacity. However, studies show that a disproportionately large number of the scientists who produce highly creative work beyond the age of forty entered their field at an older age than is usual. Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies' finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.In the argument given, the two portions in boldface play which of the following roles?

PREP2012 Plant scientists have used genetic engineering on seeds to produce crop plants that are highly resistant to insect damage. Unfortunately, the plants require more fertilizer and water togrow well than normal ones do, and the seeds themselves are quite expensive, and for most farmers the savings on pesticides would not compensate for the higher seed costs and the cost of additional fertilizer. However, since consumer demand for grains, fruits, and vegetables grown without the use of pesticides continues to rise, the use of genetically engineered seeds of this kind is likely to become widespread.In the argument given, the two portions in boldface play which of the following roles?
Magoosh Epidemiologist: Malaria passes into the human population when a mosquito carrying the malaria protozoa bites a human who has no immunity. The malaria parasite can remain for up to forty days in the blood of an infected person. The disease cannot be passed from person to person, unless a non-infected person is exposed to the blood of an infected person. Theoretically, malaria could be eradicated in any given area, if all the mosquitoes carrying malaria in that area are exterminated. If such a course of action is carried out at a worldwide level, then the global eradication of malaria is possible. Which of the following, if true, suggests that the epidemiologist's plan for eliminating malaria is not viable?
