Magoosh India ranks fifth in the world production of coffee. Popular thought has long associated India with tea and especially with masala chai, but clearly, we need to recognize India as one of the great coffee-drinking nations as well. This argument is flawed primarily because the author
Swamp sparrows live in a variety of wetland habitats. Unlike most swamp sparrows, which live in freshwater habitats, the coastal- plain subspecies lives in tidal wetlands, where freshwater and seawater mix and the mud is gray rather than brown. Coastal-plain swamp sparrows differ from all other populations of swamp sparrows in having plumage that is gray brown rather than rusty brown. DNA analysis indicates several important genetic differences between swamp sparrows that inhabit tidal marshes and other subspecies of swamp sparrows. Therefore there must have been genetic - selection pressure on swamp sparrows in tidal marshes to become darker and grayer.Select Strengthen for the statement that would, if true, most strengthen the argument, and select Weaken for the statement that would, if true, most weaken the argument Make only two selections, one in each column.
Ace Motors, an automobile manufacturer headquartered in the city of Metropolis, recently administered a survey to all executives employed at their downtown headquarters. The survey found that, among executives with similar jobs, those living in the suburbs have less free time per week than do those that live in the city proper because some of the time spent on commuting by the suburban executives is spent on leisure by the urban executives.Which of the following inferences is best supported by the statements made above?
GWD PREP08 Test 2 Wind farms, which generate electricity using arrays of thousands of wind-powered turbines, require vast expanses of open land. County X and County Y have similar terrain, but the population density of County X is significantly higher than that of County Y. Therefore, a wind farm proposed for one of the two counties should be built in County Y rather than in County X.Which of the following, if true, most seriously weakens the planner's argument?
PREP07 Test 2 PREP2012 Guitar strings often go "dead"—become less responsive and bright in tone—after a few weeks of intense use. A researcher whose son is a classical guitarist hypothesized that dirt and oil, rather than changes in the material properties of the string, were responsible.Which of the following investigations is most likely to yield significant information that would help evaluate the researcher's hypothesis?
GWD Secret passwords are often used to control access to computers. When employees are allowed to make up their own passwords, they are likely to setup as passwords their initials or birth dates. To improve security, employers should assign randomly generated passwords to employees rather than allowing employees to make up their ownWhich of the following, if true, most seriously undermines the conclusion drawn above?
OG21 OG2022 Highway Official: When resurfacing our concrete bridges, we should use electrically conductive concrete (ECC) rather than standard concrete. In the winter, ECC can be heated by passing an electric current through it, thereby preventing ice buildup. The cost of the electricity needed is substantially lower than the cost of the deicing salt we currently use. Taxpayer: But ECC is vastly more expensive than standard concrete, so your proposal is probably not justifiable on economic grounds. Which of the following, if true, could best be used by the highway official to support the official's proposal in the face of the taxpayer's objection?
PREP07 Test 2 The use of radar detectors in commercial vehicles was banned because commercial truck and bus drivers were using these devices to drive faster than the posted speed limit without fear of arrest. Since drivers of noncommercial vehicles also use radar detectors and since speeding decreases safety for any vehicle, use of radar detectors should also be banned in noncommercial vehicles to increase safety.Which of the following, if true, most strongly supports the argument above?

OG12 OG15 PREP07 Test 1 Male bowerbirds construct elaborately decorated nests, or bowers. Basing their judgment on the fact that different local populations of bowerbirds of the same species build bowers that exhibit different building and decorative styles, researchers have concluded that the bowerbirds' building styles are a culturally acquired, rather than a genetically transmitted, trait.Which of the following, if true, would most strengthen the conclusion drawn by the researchers?

Planets within the habitable zone, the shell-shaped region of space surrounding a star within which a planet could maintain liquid water on its surface, are much more likely than more distant planets to harbor atmospheres which contain water and, possibly, multicellular life.

Manhattan At any given time, approximately fifteen percent of all homes in Florida are on the market. In Texas, however, only seven percent of all homes are on the market at any given time. Therefore, one will have a wider selection of homes to choose from if one looks for a home in Florida rather than in Texas.Which of the following, if true, would most strongly strengthen the argument above?
GWD Which of the following can be inferred about supplier partnerships, as they are described in the passage?

In the past, BASE jumpers used parachutes when making their high-altitude leaps. In the past few years, wingsuits have become popular; they generate lift, allowing the jumper to glide rather than free-fall, but cause landings to take place at much higher speeds. The concern that wingsuits are more dangerous than parachutes is clearly sustained by the fact that the number of BASE jumping injuries was much higher last year than it was ten years ago.

Which of the following, if true, most seriously compromises the strength of the evidence cited?
GWD OG18-语文分册 Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-rays because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When a number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fracture initially judged stable.Which of the following, if true, most strengthens the argument?
OG18-语文分册 Conventional wisdom suggests vaccinating elderly people first in flu season, because they are at greatest risk of dying if they contract the virus. This year's flu virus poses particular risk to elderly people and almost none at all to younger people, particularly children. Nevertheless, health professionals are recommending vaccinating children first against the virus rather than elderly people.Which of the following, if true, provides the strongest reason for the health professionals' recommendation?
