The correct answer here is the one that does not explain the apparent paradox. That the new unit uses a smaller share of total electricity is consistent with its being more energy efficient. It does not explain how her electric bills could have gone up despite her installation of the more efficient unit; all other answers provide possible resolutions of such apparent paradox.

Under the modern model for music distribution, musicians sell the right to broadcast their music to companies who give listeners affordable access to large quantities of music. Some musicians who have been selling their music for many years are displeased with the new model and have seen decreased revenue. Yet, musicians as a whole are making more money under the new model than they were previously.

The paradox in the passage is that some musicians generate less revenue now than they did under the old model while, on the whole, musicians earn more revenue than previously. If there are more musicians than under the old model, revenues could increase for the industry as a whole while decreasing for certain musicians. This is not the only information that could explain the paradox, but it does so better than any of the other answers given here.

GDP (Gross Domestic Product) is one of the primary ways that economists determine the health of an economy. Unfortunately, GDP is very difficult to calculate and many economists realize that official GDP reports are inaccurate. Despite this, many economists feel that they can accurately gauge the health of an economy.
Which one of the following, if true, most helps resolve the apparent contradiction in the paragraph above?

We are looking for an answer that helps explain why economists feel like they can accurately gauge the health of the economy despite the fact that they think their primary means of doing so may have flaws. The correct answer helps resolve this paradox by showing that there could be another metric that economists use to help gauge the health of the economy. The other answers either are irrelevant or make the paradox harder to explain.

Much of the recent scholarship surrounding counter-terrorism studies has fallen under heavy criticism for its ambiguous use of labels, its lack of interviews with actual terrorists, and its inability to create reproducible results. Despite these shortcomings, Dr. Jane Waxman, a Professor of terrorism studies, has concluded that these counter-terrorism studies are very useful.
Which of the following, if true, would help explain the apparent discrepancy between the Professor’s conclusion and the problems surrounding recent scholarship on counter-terrorism?

Over the past ten years, insurance premiums have increased, resulting in a large decrease in insurance enrollment across the country. Insurance company revenues, however, have progressively increased in each of the ten years during this period, and industry analysts predict further increases in years to come.

Here, the author describes two simultaneous trends that, at first blush, seem to contradict one another. Insurance premiums have increased, which have led to a decrease in insurance enrollment. This first part is logical. However, interestingly, revenues for insurance companies have continued to rise despite the decreased enrollment. The correct answer choice must provide additional revenue that compensates for the decrease in revenue from decreased enrollment. Only the answer choice: “The decrease in the number of people enrolling for health insurance over the past ten years has been more than offset by the increases in insurance premiums” provides this increased revenue that would explain this phenomenon.

The correct answer is:
The tutoring sessions took more time than Tom had realized they would take.
This does not resolve the paradox, because even if the tutoring sessions took more time than Tom realized they would required, this does not necessarily mean that he did not have the time to utilize them. All the other answer choices do in fact resolve the paradox because they shed light on why Tom's GPA would have worsened.

Recent polls of admissions officers at colleges have shown that when evaluating student applications, volunteering is valued less than taking on leadership roles in student organizations. However, despite having this information, some high school counselors encourage students to spend time volunteering over taking on leadership roles in student organizations.

The correct answer is:
Some high school counselors believe that the personal development that can result form volunteering is more important than the competitive edge that a leadership role can earn a student applying for college.
In order to justify why a high school counselor might favor volunteering over student leadership roles, it is important to show that there is an incentive more powerful than helping a student gain an edge for getting into college. This is the only answer choice that provides such an incentive. Therefore, it is the correct choice.

It is time to face the fact that public libraries throughout the country should be converted to fitness facilities. The country's citizens are progressively becoming less healthy and must have access to fitness facilities in order to improve health. Meanwhile, public libraries take up space but do not provide value to the public. The best course of action is clear.
The author of the passage is most likely to agree with which of the following?

The author does not make a judgment about the historic value provided by public libraries, leaving that question open. The author does state, however, that citizens "must have access to fitness facilities in order to improve health." Thus, the author apparently holds the view that access to fitness facilities is necessary for improved health.

Smoking cigarettes continues to be a common practice despite countless studies demonstrating that the habit causes deadly diseases. The government has attempted to reduce the number of smokers with advertising campaigns that explain the consequences of smoking, but the campaigns have been ineffective because the habit continues to be as prevalent as it was previous to the campaigns. The government should try one or more of the many alternatives to advertising. For instance, the government could raise the tax on cigarettes to the extent that smoking is prohibitively expensive.
Which of the following, if true, most weakens the argument?

A key premise of the argument is that the government's advertising campaign has been unsuccessful because smoking is as prevalent as it was prior to the campaign. The campaign may still be successful, however, if campaigns are generally successful only after many years. The new information would undermine a fundamental premise of the argument.

Eye surgery has become a viable alternative to wearing glasses. There have been questions about long term effectiveness for many years, but the doubt seems to be disappearing. Few people have reported negative effects even years after surgery and many people say their improved vision has lasted. We should see the demand for eye surgery increasing drastically as a result of doubts being dispelled. Yet, the number of people obtaining eye surgeries remains relatively constant.

Two years ago, the state legislature significantly increased the fines for distracted driving offenses in an attempt to reduce traffic accidents. The legislature also made such offenses more severe with regard to possible driver license suspensions, and publicized the new penalties on highway signs and television commercials. Yet recent studies show that since the changes, the number of tickets for distracted driving has actually increased statewide.

The correct answer choice resolves the discrepancy by explaining that an overall population increase could increase the total number of tickets despite the deterring effects of the legislative change. Note that it is the total number of tickets, not the average tickets per person, that has increased. The only other answer choice that comes close to explaining the discrepancy is that some drivers are unaware of the changes. However, this answer choice is weak, as it only applies to “some” drivers; more importantly, it does not explain why the total number of tickets has increased rather than stayed the same. The other answer choices are not useful in explaining the discrepancy.

The owner of a local convenience store wants to increase store revenue. Soft-serve ice cream machines provide a cheap snack for customers on a hot day and also produce ice cream at a low production cost. The owner of the local convenience store installs a soft-serve ice cream machine to increase revenue. After the soft-serve ice cream machine is installed, the revenue of the store goes down.
Which of the following best explains the drop in revenue?

If the customers start buying cheap snacks instead of expensive snacks, that could explain the drop in revanue. If the icecream brings in more customers and if those customers spend less there is the possibility that it could increase revenue. Maintenance costs are expenses not revenue. Finally, be careful to avoid answers that are not relevant to the question or that do not make sense, such as the ‘relative impact’ answer.

The relative number of each type of structure in a given area does not explain why one was damaged and another was not (the question did not say that MORE apartments were damaged than mobile homes). The question also did not say anything about the occupants inside the homes, and whether or not occupants are in the home does not determine whether or not the homes themselves are damaged. The fact that all buildings are somewhat vulnerable does not explain the difference in damage. The only answer choice that explains the unexpected difference is the one that implies that the structure that is typically supposed to be stronger was somehow weakened in a previous event.

The professor's lecture is stated as being incomprehensible to his students, but that they are hopeful that the subject matter can be made clear through the textbook. This paradox, that the students think they can understand the material although not understanding the specific lecture, can be resolved by the fact that the textbook will explain the material in a much clearer manner than the professor.
