Advice from a computer security expert, on passwords used for accessing online accounts:Computer users should use a different password for each online account. They should also use strong passwords, which are hard for hackers to decipher. However, strong passwords are difficult to remember, and this is especially the case for users who have multiple online accounts.Fortunately, software is available for little or no cost that can store and encrypt a user's passwords: the user need only remember one password to access the rest. For users willing to take the time to install the software on a computer and enter all the required data, such software provides one way to comply with security expert's advice. Some versions of the software can even be copied to a portable device, such as USB drive, whereby a user can access passwords from any compatible computer.For a computer user with multiple accounts who would not otherwise use a different strong password on every account, the expert's advice amounts to suggesting that users make certain sacrifices in order to make certain gains. Indicate by appropriate selections in the first and second column which of the items in the third column would describe a sacrifice for this user and which would be a gain. Make only two selections, one in each column.
Researcher: Soils are adversely affected by road salts used to melt ice and snow, particularly along roadsides and salt storage areas. Soil samples were collected from highway medians and in salt storage yards. These samples showed chloride levels 11-160 times the level sufficient to inhibit bacteria growth in soil. Inhibited bacterial growth in soil greatly inhibits plant growth in that soil.An agricultural official would like to use the researcher's result to support the argument that sand, rather than road salts, should be used as a winter road treatment, thereby eliminating the need for salt yards. Select the additional information that, if true, would most strengthen the official's case and select the additional information that, if true, would most weaken the official's case.

The PQ&R art gallery seeks high-quality works of art with elements that match a certain theme. Though each submitted work of art will be considered on its own merit, the submissions will be initially divided into groups based on how the description of the work satisfies the criteria in the gallery's Call for Art. Group A will consist of the works with a description that satisfies all of the criteria. Group B will consist of artwork whose description satisfies some but not all of the criteria. Group C consists of artwork with a description that satisfies none of the criteria.Call for Art: with the proliferation of communication technology, the human identity has retreated to the face – especially the eyes; technology now approximates an individual's humanity. Our next exhibit will be about humanity, the human face, and technology. We seek works of art with subject matter that reflect these three elements of this new supposed reality.The following are descriptions of works of art submitted for the exhibit. Select the work that will be placed in Group A and select the work that will be placed in Group C. make only two selections, one in each column.
Javier rates his work-readiness on a scale from 0 to 10 points, with 10 being maximum readiness. He wants his rating to be as high as possible when he arrives at his office and has found that the rating is affected by how late he sleeps and how long he spends preparing for work. His alarm clock sounds at 6 a.m., at which time he has a work-readiness rating of 10. He needs to leave for work at exactly 6:40 am. During these 40 minutes, Javier's only activities are sleeping or preparing for work.If Javier spends more than 25 minutes or less than 10 minutes to prepare, his rating is reduced by 5 points. To sleep past 6 a.m., however, Javier must use the snooze button on his alarm clock, which delays the alarm by 4 minutes. Each press of the snooze button after the third will decrease Javier's efficiency rating by 1 point.In the following table, select for rating the greatest work-readiness rating that Javier can achieve and select for Snoozes the number of times he must press the snooze button to achieve that rating. Make only two selections, one in each column.

OG17 OG18 Naturalist: the decline of coral reefs has various causes. One contributing factor is predation on coral by organisms such as the crown-of-thorns sea star, whose preferred food source is coral polyps. Human fishing practices have decreased the sea star`s predators, such as the harlequin shrimp. It is also possible that runoff containing nutrients for phytoplankton has resulted in larger phytoplankton blooms: the crown-of-thorns sea star gladly eats phytoplankton.Indicate in the table which cause-and-effect sequence would most likely, according to the naturalist, result in coral reef decline. Make only two selections, one in each column.
TPA For each values of y greater than $$2\sqrt3$$, the function f(x) is such that the equation f(x)=y has the form $$x=\frac{(y^2+12)}{y}$$.Select one value for a and one value for b such that the given information implies f(a)=b. make only two selections, one in each column.
Journalist: the end of the Triassic, the geologic period that extended form about 250 to 200 million years ago, has traditionally been blamed on volcanic eruptions that went on for 600,000 years. However, a researcher has recently suggested that these eruptions were only an indirect cause. By analyzing the isotopic composition of hydrocarbon molecules from plant waxes from the period, he discovered what looks like a spike in the amount of nonbiological carbon in the atmosphere, lasting between 10,000 and 20,000 years. The researcher believes that the release of methane—a carbon-containing greenhouse gas much stronger than carbon dioxide—stored at the bottom of the ocean was the direct cause of the end of the Triassic.The journalist suggests that a certain causal sequence may have brought about the end of the Triassic period. Identify in the table the sequence of cause and effect most strongly suggested by the journalist to have resulted in the end of the Triassic. Make only two selections, one per column.

Granted, Switzerland and the United States diverged in the degree to which the expansion of industry coincided with the degree of urbanization: only 29 percent of the Swiss population lived in cities of 10,000 or more inhabitants by 1920. However, urbanization cannot fully explain women's suffrage.第一句和第二句之间的关系是：
But ethologists—specialists in animal behavior—are interested in evolution, so they define the term narrowly.They insist that mutations in a behavioral gene must alter a specific normal behavior and not merely make the organism ill, so that the genetically induced behavioral change will provide variation that natural selection can act upon, possibly leading to the evolution of a new species.第一句和第二句之间的关系是：
The 1850 census, partly responding to antislavery and women's rights movements, initiated the collection of specific information about each individual in a household.

PREP2012 Which of the following most logically completes the passage below?One name-brand cereal manufacturer is about to reduce wholesale prices for its cereals by 20 percent because consumers have been switching from its cereals to cheaper store brands. The success of this strategy relies on the assumption that supermarkets will pass on all of the savings by lowering the prices they charge consumers for the manufacturer's cereals. Although supermarkets usually pass on such savings, in this case it is likely that supermarkets not do so because______.
PREP2012 Theatergoer: In January of last year, the Megaplex chain of movie theaters started popping its popcorn in canola oil, instead of the less healthful coconut oil that it had been using until then. Now Megaplex is planning to switch back, saying that the change has hurt popcorn sales. That claim is false, however, since according to Megaplex's own sales figures, Megaplex sold five percent more popcorn last year than in the previous year.Which of the following, if true, most seriously weakens the theatergoer's argument?
PREP2012 Pretzel vendor: The new license fee for operating a pretzel stand outside the art museum is prohibitively expensive. Charging typical prices, a vendor would need to sell an average of 25 pretzels per hour to break even. At my stand outside city hall, I average only 15 per hour. Therefore, I could not break even running a pretzel stand outside the art museum, much less turn a profit.Which of the following, if true, most strongly supports the pretzel vendor's argument?
