It is immoral for a government to enter a war unless its own citizens have been attacked. To avoid taking immoral action, governments should receive international approval before entering a war in another country, no matter the cost.
Which of the following, if true, provides the most support for the argument?

Which of the following, if true, provides the most support for the argument?
Tap to reveal answer
An apparent weakness of the argument is that a government might receive international approval for going to war even when its citizens have not been attacked. If a government could never receive international approval for such a war, then this would no longer be a weakness.

Some arguments for expanding U.S. oil production are misguided. Vehicles that do not burn gasoline will be readily available within fifty years, and vehicles that do not burn gasoline do not require oil production. Furthermore, any job creation benefits from increased oil production would be offset by the negative economic effects of producing a product that will not be in demand. Alternatively, jobs can also be created by increased development of oil alternatives.
The argument is strengthened by all of the following, if true, except:

When car manufacturers place a high priority on generating large profits, they neglect their responsibility to make safe cars. Those manufacturers with the highest profits also make the most unsafe cars. Car manufacturers should be less concerned with generating large profits in order to improve car safety.

Common perceptions aside, people are safer from crime in urban areas than in rural areas. The reason for this is that there are more people available to prevent crimes in urban areas and police can respond more quickly than in rural areas. For instance, a person who yells for help after being robbed is more likely to be heard in an urban area. It is also likely that a police officer will arrive more quickly because there are more of them in urban areas.

Professional football teams should more often select new players from colleges with uncompetitive football teams. Most professional teams target players from competitive college teams, leaving few competitors for teams who select from less competitive colleges. Those who take a different view incorrectly believe that there are few talented players at uncompetitive colleges. The reality is that even very uncompetitive teams may have exceptionally talented individual players.

The Democratic Party, despite being more popular than the Republicans in a recent national poll, will not retake the House of Representatives this upcoming election. This poll does not account for the fact that most incumbent Republicans poll much higher than the rest of their party, the Democratic Party does not have eligible candidates to challenge most seats, nor that recent changes in election laws give the better-funded Republican Party the opportunity to flood television with attack advertisements.

Academics in theology departments generally agree that there are fewer religious people today than fifty years ago. There are two primary critiques of that view, however. First, the conclusion depends on a definition that is highly subject to debate. If “religion” is defined as a strongly held conviction about the purpose of the world, for instance, the academics may be incorrect. On the other hand, the conclusion would be justified if "religion" is defined as a belief in a supernatural god. Second, the academics base their conclusion almost exclusively on data collected from the western hemisphere.
Which of the following, if assumed, strengthens the conclusion of the academics?

None of the answers responds to both objections. If the academics' conclusion applied only to the western hemisphere, however, then the second objection would be defeated and the academics' conclusion would be strengthened. At first glance, the answer that "most people believe 'religion' should be defined as a belief in a supernatural god," seems like an equally correct answer; but this does not directly refute the claim that the definition is "subject to debate."

A new government report claims that the current administration has curtailed its domestic surveillance program. However, the report maintains that specific programs within the domestic surveillance infrastructure the government maintains will remain classified. In the past when the government has kept information classified, the visible reforms the government has performed have been negated by secret expansions. Thus, we know that the current administration has failed to curtail its domestic surveillance program.

Intellectual property rights are essential to providing incentives for pharmaceutical companies to innovate and create new medicines. Despite this, the government should be willing to curtail some intellectual property rights. Millions of people are dying of various diseases and the fact that some pharmaceutical companies have exclusive rights to produce certain drugs means many people are unable to purchase those drugs.

The correct answer is:
The newspaper company has lowered the prices of the paper in order sell more; however, the increase in sales does not offset the lower price point.
This is because lowering the price of a product will only increase revenue if a sufficient amount of the product is sold. If the newspaper company did not sell enough of its product, then it follows that revenue would decrease.

Psychologist: Intelligence cannot be adequately captured by a single number, such as an IQ score. There are different types of intelligence, including social, emotional, and kinesthetic. Indeed, these forms of intelligence may be even more important than IQ when it comes to everyday functioning and life satisfaction. Humans face different types of challenges, many of which cannot be expressed or measured in a standardized test. It is, therefore, likely that IQ scores are overvalued in our society, and should be de-emphasized.

Transcriptionist: To be a successful transcriptionist, you must focus on improving your typing speed. But “words per minute” alone is not the best measure. You should instead focus on being able to quickly and accurately type long passages of at least five hundred words. You need to encounter a variety of different words, numbers, and types of punctuation. Shorter passages, while useful to obtain a higher maximum speed, are insufficient to sustain speed over the long term.

A study of history is necessary to understand science, which means understanding the scientific method. The scientific method has developed over the centuries, and though now taken for granted, has certain underlying assumptions which must be realized in order to fully understand its limitations. For instance, five hundred years ago it was not assumed that one had to develop a working hypothesis prior to beginning experimentation. Back then the steps could be taken out of order or skipped altogether. Such ideas are unheard of in today’s scientific community, and we need more scientists who are fully aware of how this came about.
