Inverse beta decay, the subatomic interaction by which an electron and a proton are "crushed" into a neutron, the process in which the recoil, on a massive scale of an entire stellar nucleus, pushes out the outer layers of the star in the cataclysmic explosion of a supernova and transforming the stellar nucleus into a neutron star.

That the Fifth Lateran Council (1512 – 1517), had it addressed the growing concerns of reformers within the Catholic Church rather than simply shoring up its own political prerogatives with respect to the monarchies of Western Europe, could have avoided the series of events that led to the Protestant Reformation still causes regret among modern Western Christian thinkers.

Economist: In today's post-industrial economy, higher education is essential for achieving prosperity. Without a college degree or higher, citizens do not have access to the highest quartile of salaries, and only individuals earning salaries in this highest quartile have enough disposable income to buy real estate and invest in long term assets. The argument assumes that

A manager is hoping to reach a certain target for camera sales in his store, which sells between 10 and 20 cameras a week. Typically, most cameras sold in any week are the less expensive economy models, and his store has sold relatively fewer of the more expensive, high-end cameras. The manager realizes that if, on average, three more cameras sold each week were high-end instead of economy models, the store would reach its target in sales. The manager prepares a detailed information sheet for the sales associates, outlining the numerous advantages of the high-end cameras over the economy cameras, and provides each sales associate with a portfolio of contrasting photos of the same images, showing the clearly superior image quality of the high-end cameras. Which of the following, if true, would provide most support for the prediction that the detailed information sheet and photo portfolio given to sales associates will have its intended effect of allowing the store to reach its target in sales?

The excessive paperwork used to process claims at Brakeland Insurance Company, not the increase in accident claims involving privately owned cars, is responsible for the declining profits at Brakeland since the appointment of its new CEO. Sterling Auto Insurance Company has seen a similar increase in accidents among its insured vehicles, but while Brakeland's profits have decreased, Sterling's have increased in the same time period.Which of the following, if true, would most weaken the argument above?

Benford's Law states that most phenomena in nature begin with '1's and '2's. The law has been shown to apply very accurately to the amount of money listed on people's income statements. Investigators have used this fact when investigating financial fraud, and can often determine when people have fabricated numbers, since the perpetrators will choose varying amounts so that the first number in each of those amounts is distributed evenly from '1' to '9'. Proponents of Benford's Law, therefore, argue that as the technique of applying Benford's law becomes even more refined, an expert's ability to determine whether a plaintiff has engaged in financial fraud will become as accurate in determining guilt as a fingerprint is today.Which of the following, if true, casts the most doubt on the conclusion drawn by proponents of Benford's Law?

Accidents involving drivers who do not wear seatbelts have been shown to cause higher rates of serious injury than accidents involving drivers who do wear seatbelts. Because drivers who do not wear seatbelts can end up costing taxpayers money in medical bills, Thoracic County should make it illegal to drive without a seatbelt.Which of the following, if true, provides the most support for the argument above?

Flagpole Army Base in Oregon and Klondike Army Base in Alaska are similar bases with similar duty loads. Despite the similarities, Klondike always has had more men than Flagpole has. Clearly, each soldier at Klondike must have to perform a smaller share of the duties, and therefore soldiers at Klondike must have more free time than do soldiers at Flagpole.In evaluating the argument, it would be most useful to know which of the following?

Studies have shown that highway drivers are less likely to drive at speeds greater than the posted speed limit if houses or buildings are in some way visible from the road. Assuming similar car, road and traffic conditions, highway drivers are more likely to drive at speeds in excess of the posted speed limit if the natural surroundings are not interrupted by buildings. Psychologists hypothesize that seeing signs of civilization reminds drivers of their responsibility to the safety of their fellow humans, thus making them more likely to obey the posted speed limit.
Which of the following, if true, most strongly supports the psychologists' interpretation of the study?

In the past decade, two Motorlux models, the T-300, a sports car, and the AG-75, a sports utility vehicle, have been manufactured with the same timing belt, which controls the timing of the engines valves: when the engine is running at a higher RPM, there is more strain on the timing belt. Recent evidence indicates that this particular brand of timing belt has a usable life of about 135,000 miles, somewhat less the 200,000 miles life typical of standard timing belt. Although the same model of timing belt has been used for both models of cars, the incidence of timing belt failure is considerably higher in the AG-75 than in the T-300. This is most likely because ______________________

A deadly virus that has claimed the lives of local villagers has been traced to the spotted fruit bat, in which the virus resides between periodic outbreaks. Biologists speculate that the bat might also be one of the reservoirs for a number of other viruses that have led to village fatalities. The local government has proposed to eliminate the spotted fruit bat by cutting off passageways that allow the bat to emerge from its caves. Once the bat is unable to emerge from the caves, the government will have achieved its objective of reducing the number of village deaths attributable to viruses.
Which of the following, if true, would best indicate that the government's plan will not lead to its objective?
