As part of a study conducted by the Lexington University’s Psychology Department, two groups of volunteers from the university’s classical music program performed Claude Debussy’s Claire de Luna. Then, one group was provided verbal feedback in a jovial tone, while the other was provided verbal feedback in a neutral tone. Some volunteers, chosen randomly from each group, were then encouraged to enjoy a warm beverage of their choice. Among those who received verbal feedback in a neutral tone, those who accepted a beverage were significantly less likely to volunteer for another, similar experiment than those who did not accept a beverage. The researchers concluded that some of the volunteers chose not to volunteer again, partly because they received feedback in a neutral tone.

Which of the following would, if true, most help to support the researchers' conclusion?

A. Among the volunteers who received feedback in a jovial tone, those who accepted a beverage were significantly less likely to volunteer for another, similar experiment than those who did not accept a beverage.
B. Just as many volunteers from one group were encouraged to enjoy warm beverages as from another group.
C. Most of the volunteers encouraged to enjoy a beverage accepted one.
D. The volunteers were not more disposed to drinking warm beverages under typical circumstances than the general population was.
E. Those who received feedback in a jovial tone were, on average, more likely to volunteer for another, similar experiment than those who received feedback in a neutral tone were.

Looking to improve student performance in the suburb of Backport, the Mayor of Grantsville has decided to initiate a series of improvement projects for the three public schools that serve the suburb. The Mayor plans to fund these improvements over the course of the next four years by raising property taxes in the neighboring suburb of Gadsen. Although these improvements are surely needed, the Mayor’s plan to fund them should be rejected because it would unfairly force the residents of Gadsen to absorb the entire cost of initiatives from which they receive no benefit.

Which of the following, if true, would provide the Mayor with the strongest counter to the objection that her plan is unfair?

A. Even with the proposed tax increase, property taxes in Gadsen would remain less than property taxes levied in most of the other suburbs of the city.
B. The public schools that serve the suburb of Gadsen are overcrowded and residents of the suburb benefit when some families choose to send their children to schools in neighboring suburbs.
C. The residents of Gadsen benefit from the commuter roads leading to the city center, and the maintenance of these roads is funded out of general income tax revenues from both Backport and Gadsen.
D. Any attempt to finance the improvements by raising property taxes in Backport would result in fewer families with school-going children moving to Backport and so would be at least partially self-defeating.
E. The only alternative way to fund the proposed improvement initiatives now being considered is through a regional income tax surcharge, which would affect the residents of Backport and the residents of Gadsen alike.

Agriculturalists have noted that soil with an abnormally low proportion of nutrients such as magnesium and potassium is usually acidic, which severely hampers crop growth. Thus, agriculturalists recommend treating soil with nutrient-heavy fertilizers such as lime, wood ash, and Epsom salts to prevent soil acidity.

Which of the following, if true, most strongly suggests that it would not be advisable to follow the agriculturists’ recommendation?

A. Soil acidity alters the chemistry of soil in a way that makes it difficult for it to absorb nutrients such as magnesium and potassium.
B. Soil acidity can resolve itself without intervention, sometimes.
C. Lime contains elements that are not easily absorbed by many types of soil.
D. Epsom salts are not easily available in all regions.
E. Low magnesium and potassium levels in soil can in some cases be fixed through composting.

A carbon credit is a permit that allows a company to produce a certain amount of greenhouse gases. The government issues the credits to companies who invest in environmental initiatives. After reaching their limit for greenhouse gas production, larger companies sell their remaining credits to smaller companies for less than the smaller companies would need to invest in environmental initiatives to earn the credits themselves. This practice has resulted in a drop in investment in environmental initiatives.

To discourage the purchase and sale of carbon credits, it would be best if the government restricted

A. how many credits a company can earn per year
B. the industries that can use the credits
C. in which months of the year the additional credits can be used
D. how much time may elapse between the issuing and use of the credits
E. the use of the credits to the companies that earned them and the companies’ subsidiaries

The government’s efforts to stifle the import of foreign electronic items failed in 2000. If these efforts had been successful, the wholesale price of most electronic items would not have dropped substantially in 2000.

The argument in the passage depends on which of the following assumptions?

A) The foreign electronic goods supply fell considerably in 2000.
B) In 2000, the drop in the wholesale price of most foreign electronic items was not solely because of the drop in the demand of such items.
C) The domestic production of electronic items increased at a higher rate than did the import of such items.
D) In 2000, the wholesale price of a few foreign electronic items increased considerably.
E) The price to the average consumer for foreign electronic items did not drop considerably in 2000.

Textile engineers have created a fiber coating to produce fabric that prevents viruses from adhering to the surface. However, the coating is fairly expensive, and the fabric consumes more chemicals and water in its production than do traditional fabrics. Resultantly, for the majority of textile companies, the increased earnings from the new premium fabric would not offset the costs of the fiber coating and additional chemicals. Yet, as demand for garments that can repel viruses continues to rise, the use of coated fiber of this type is expected to spread extensively.

In the argument given, the two portions in boldface play which of the following roles?

A. The first presents a development that the argument predicts will lead to a certain result; the second recognizes a consideration that tends to weigh against that prediction.
B. The first provides a context for the argument; the second is the main conclusion of the argument.
C. The first introduces a development that the argument predicts will lead to a certain result; the second is a state of affairs that, as per the argument, contributes to bringing about that result.
D. The first provides evidence to support a prediction that the argument seeks to defend; the second is that prediction.
E. The first and the second each provide evidence that supports the main conclusion of the argument.

The oldest extant iteration of Gameco’s coding engine is forty years old. The fact that the code used in this engine frequently uses lower-level programming languages indicates that Gameco formulated its coding practices at least ten years before the aforesaid coding engine was produced. Keep in mind, Gameco adopted its coding engine from Crytek; presumably, alongside the coding engine, Gameco also adopted Crytek’s then-current practices regarding the programming languages employed. And although Crytek coding was originally an amalgamation of lower- and higher-level languages, forty years ago, Crytek was consistently using higher-level languages, and had been doing so for about ten years.

In the argument given, the two portions in boldface play which of the following roles?

(A) The first and the second each describe evidence used to challenge the position that the argument seeks to establish.
(B) The first is evidence on which an objection to the position that the argument seeks to establish is based; the second is that position.
(C) The first and the second each provide evidence supporting the position that the argument seeks to establish.
(D) The first is evidence on which an objection to the position that the argument seeks to establish is based; the second is a consideration the argument introduces to counter the force of that evidence.
(E) The first provides evidence supporting the position that the argument seeks to establish; the second is that position.

Many have suggested that increased qualification standards have been the primary cause of the present recruitment shortfall in the navy. However, the shortage has actually been caused by the facts that in recent years, seamen have not experienced any improvements in the work environment and that their salaries have not kept pace with salaries in the other branches of the armed forces.

Which of the following, if true, would most support the claims above?

A. Many seamen already in the navy would not have been recruited under the new qualification standards.
B. Many seamen have cited low pay and confined workspace as reasons for leaving the navy.
C. Some seamen have cited increased standards for qualification as a reason for the current recruitment shortfall.
D. Today more seamen are joining the navy with a higher educational level than in the past.
E. Many prospective seamen have cited the new qualification standards as a reason for not joining the navy.

A common contention among economists is that if they could build an accurate mathematical model that accounted for all economic variables, they could effectively foretell the results of any economic action. But this meaningless conjecture cannot be evaluated because any inadequate predictions would obviously be blamed on imperfections in the model.

Which of the following, if true, would cast the most serious doubt on the economists’ conjecture?

A. The monetary supply produced and maintained by nations across the world is carefully observed and known to be inconsistent.
B. With existing economic models, large scale economic shifts can be predicted with greater accuracy than can relatively local changes in the economy.
C. As existing economic models improve, even small increments in complexity will require large increases in the number of computers required to implement the improved models.
D. Frequent, precise data regarding the decisions of governments and major corporations, as well as accurate predictions regarding upcoming climactic changes, are a prerequisite for constructing an accurate economic model.
E. Irrational human behavior, unexpected natural disasters, and several other processes that also cannot be quantified accurately are known to significantly and continuously affect the economy.

Research shows that experimental stem cell procedures designed to repair organ damage primarily affect the integrity of the organ tissue rather than the growth of individual cells within the tissue. Therefore, analyzing the effects of such treatments on the health of the individual cells is irrelevant. Rather, the effectiveness of these treatments should only be assessed at the tissue level.

Which of the following would it be most useful to establish in order to evaluate the argument?

A. Whether two methods to measure the integrity of the treated tissue usually give similar judgment
B. Whether the health of individual cells can be effectively analyzed without introducing factors that may impact cell health positively or negatively
C. Whether the health of individual cells affects the integrity of organ tissue
D. Whether some organs can repair comparable levels of damage without the treatment
E. Whether the research has shown that the stem cell procedure effective in treating one organ can repair damage to another organ
