An American manufacturer of racing bikes reported a 1996 second-quarter gross income of $18 million, compared with $11.5 million in the second quarter of 1995. This increase was realized despite a drop in U.S. sales of racing bikes in 1996 compared with 1995, which was partly attributable to the unusually high sales in 1995 as a result of the unprecedented success of an American cyclist in a high-profile international race.
Which of the following, if true, would contribute most to an explanation of the increase in the manufacturer’s gross income in 1996?
Casinos often employ shills in order to create an environment of fun and excitement for customers. Shills are outgoing people who are paid to sit in the casino and play casino games. When shills are on duty, customers experience a livelier casino floor and are more likely to play casino games and to play for longer periods of time. Although casinos retain any money that shills win in card games such as poker, they allow shills to keep any money they win at slot machines while they are on duty. Therefore, shills should be able to keep any money they win playing "Chicken," a new game in which a live chicken chooses the cards that a player will receive.
The conclusion above would be drawn more logically if which of the following premises were to be added to the argument?

When an ordinary piece of steel is put under pressure, the steel compresses; that is, its volume slightly decreases. Glass, however, is a fluid, so rather than compressing, it flows when put under pressure; its volume remains unchanged. Any portion of a sheet of glass that is under sustained pressure will very slowly flow to areas under less pressure. Therefore, if a single, extremely heavy object is placed in the middle of a horizontal sheet of glass of uniform thickness and if the glass is able to support the weight without cracking, then the sheet of glass will eventually_________.
Which one of the following most logically completes the argument?
Kale has more nutritional value than spinach. But since collard greens have more nutritional value than lettuce, it follows that kale has more nutritional value than lettuce.
Any of the following, if introduced into the argument as an additional premise, makes the argument above logically correct EXCEPT:
Alan: In the last 15 years, most of the criminals who were convicted of theft or murder were from the lower income classes and had not completed high school. Therefore, the government has to spend more money on reducing poverty and increase funding to education. Because terrorism is the most severe of all crimes, such measures would bring down overall crime rate and reduce threat from terrorism.
Dylan: A study that was conducted in a country known to produce a number of terrorists showed that on average the terrorists were better educated than the overall population and that they did not necessarily come from lower income classes. This is probably because crimes such as theft are committed for personal gain while terrorism is for political or religious gain.
Which of the following best describes Dylan's response to Alan?
Dr. Godfrey: Now that high school students are allowed to work more than 15 hours per week at part-time jobs, those who actually do so show less interest in school and get lower grades than those who do not work as many hours at part-time jobs. Obviously, working long hours at part-time jobs during the school year contributes to the academic problems that many of our high school students experience.
Dr. Nash: That’s not so. Many of our high school students set out to earn as much money as they can simply to compensate for their lack of academic success.
The answer to which one of the following would be the most helpful in determining whether the conclusion that Dr. Godfrey draws could be logically defended against Dr. Nash’s counterargument?
The ruins of the prehistoric Bolivian city of Tiwanaku feature green andacite stones weighing up to 40 tons. These stones were quarried at Copacabana, which is across a lake and about 90 kilometers away. Archaeologists hypothesize that the stones were brought to Tiwanaku on reed boats. To show this was possible, experimenters transported a 9-ton stone from Copacabana to Tiwanaku using a reed boat built with locally available materials and techniques traditional to the area.
Which one of the following would be most useful to know in order to evaluate the support for the archaeologists’ hypothesis?
Many countries are deliberating whether they should start taxing the aviation industry for its fuel usage as a possible way to motivate it to reduce the emissions of greenhouse gases. The problem is rather severe. With the increasing affordability of airline tickets, it is estimated that by 2050 the aviation industry will be one of the key contributors to the CO2 emissions worldwide. Also, CO2 and the other gases emitted by aircraft could be even more damaging to the environment because
Which of the following best completes the passage above?
Very powerful volcanic eruptions send large amounts of ash high into the atmosphere, blocking sunlight and causing abnormally cold temperatures for a year or more after the eruption. In 44 B.C. there was a powerful eruption of Mount Etna in Sicily. In the following year, Chinese historians recorded summer frosts and dimmed sunlight in China, thousands of miles east of Sicily. If these phenomena were caused by volcanic ash in the atmosphere, then the ash sent into the atmosphere by Mount Etna’s eruption must have spread over great distances.
In evaluating the support given for the conclusion advanced in the last sentence of the passage, it would be most important to determine whether
The Timas are members of an indigenous tribe of relatively closely related people who have for centuries occupied an area now located partly within the nation of Gredaria and partly within the nation of Lexica. In the Timas who live in what is now part of Gredaria, the rate of diabetes is extremely high in comparison with the rate in people in general; 38 percent of the Timas in Gredaria are currently experiencing diabetes. As the Timas in Gredaria tend to consume large amounts of heavily processed foods, their high rate of diabetes must result from their dietary choices.
Which of the following, if true, would provide further evidence supporting the above conclusion?
