dog when they go into the park together during the daytime.

Which of the following can be inferred from the passage?

Billy: Karate movies are the best movies to watch with a date. Think of it this way: If your date can’t enjoy a dumb movie, then you probably do not want to continue hanging out with her. But, if your date is cool enough to like a karate movie, then she would probably like other, more meaningful movies too. Either way, going to a karate movie will allow you to tell immediately if your date is someone you want to hang out with.

In 2004, 60 million Americans worked for more than 40 hours a week on average, and approximately 55 million Americans found their jobs to be unreasonably demanding. These figures demonstrate that a relatively small portion of those who worked for more than 40 hours per week on average did not find their jobs to be “unreasonably demanding.

” Which of the following is a logical flaw of the argument?

Somnambulist: A person should invest a serious amount of time in choosing a bed. Instead of ordering a bed from a catalog or just going to the store to look at one, a person should bring a new mattress home for a couple of days and sleep on it before buying it. This will give the person a good idea about whether he or she will be comfortable sleeping on the purchase from then on. Many people do not realize that they can become unconsciously disgruntled with their bedroom selection, and that it will cause incessant troubles for them in their subconscious life. People should realize that humans spend half their lives asleep.

Which of the following functions does the last sentence play when the entire passage is considered?

Professor: A healthy prenatal environment is the most vital factor in producing an intelligent offspring. The steroids, minerals, and vitamins that are transferred into prenatal brains jumpstart cranial enlargement and neurodevelopment. There is simply no way for infants who experience malnourishment in their prenatal environments to catch up with other children who were not malnourished.

Doctor: Practically speaking, very few children experience malnourishment in their prenatal environment. A much larger portion of the population experiences malnourishment in their neonatal environment. On average, this neonatal inadequacy of diet holds larger implications for the intelligence of offspring than the specifics of the prenatal environment.

Which of the following is the point at issue between the professor and the doctor?

Many critics believe that music causes emotions. The lyrics, chords, and melodies of songs inspire our souls and pluck at our heartstrings, making listeners respond with a passion and zeal for life that cannot be similarly produced by any other human endeavor. It has not been until recently, however, that we as a culture have been able to realize this quality of music, because only since the 1920s has music been commercially available. Hundreds of millions of sales of CDs, tapes, and phonographs make it apparent that music is incredibly evocative and can be factored into people’s lives, wherever and whenever they want it, by the simple pressing of a “play” button. Before music’s commercialization, a person could not have had such easy access to music, and therefore, it was not possible for music to have such a huge impact on anyone’s life.

Which of the following, if true, would most support the conclusion that society has only recently realized the evocative quality of music?

Lobbyist: The airborne pollution made by automobiles has little to no effect on people’s everyday lives. After all, the increase of the CO2 concentration in breathable air affects only those living in big cities, because by the time the city air has diffused to the countryside, trees have been given the time to filter out excess CO2 and replace it with pure oxygen. Therefore, there is no reason to strengthen the regulations on vehicular exhaust fumes.

Which of the following would most weaken the lobbyist’s argument?

All basketball players hate the rain. All people who hate the rain do not like cats. Many tall people are basketball players.

Which of the following would need to be assumed in order to reach the conclusion that no one who owns a cat is a basketball player?

The great Roman Julius Caesar was hated by all Roman citizens. This animosity is shown by historians through multiple documents describing the circumstances surrounding Caesar’s death. These documents reveal that in the end even his best friend, Brutus, wanted to kill him. Roman politicians and senators also conspired to bring about his death.

A flaw in the argument is that the author

It has been claimed that many people who own video game systems do not use them. This is preposterous because it is impossible for someone to own something that would bring so much happiness and not use it constantly.

The reasoning above is analogous to the reasoning in which of the following?

Captain: The Bermuda Triangle is a place of great danger, where the seaweed has eyes, where there are ghost ships in the fog, where grisly squid will envelop a boat and pull it and its crew into the depths. My crew will never return to this dreadful place, no matter how thirsty they may be for adventure and riches.

First Mate: Captain, I respect your wishes and utterly agree with you about the dangers of the Triangle, and about the crew’s reluctance to return there. But as soon as we return home, you are scheduled to sail through the Bermuda Triangle to Africa. Am I to cancel this voyage for you?

Which of the following is the point at issue between the captain and the first mate?

Musician: People enjoy music because it stirs the native passions latent in everyone’s soul. Even the most uptight and rigid person relaxes when hearing a good jazz tune. The most depressed human being lightens at the sound of Bach’s “Air in G.” Music fills a person with any emotion he or she would like to feel. All someone has to do is pick a song and play it to suddenly be filled with the emotion that the song was designed to evoke in its listeners. In the next voting term, people should vote to raise school spending on music programs.

Which of the following roles does the assertion that people should vote for increasing school spending on music programs play in the argument?

The American Revolution was at first greeted with widespread cynicism. Almost no one truly believed that a bunch of disheveled American soldiers could defeat the English army, an army that was more than likely the world’s most powerful one since the early Renaissance. Eventually as the war wore on, Americans realized that they would not really have to defeat the English army; they would just have to force them into a stalemate through the use of guerrilla warfare. After realizing this, Americans began to feel very positive about the revolution. They foresaw that America could cause England to lose its resolve and that eventually the king would relinquish his efforts to dominate American soil.

Which of the following is the main point of the passage?

Sports gambling is a dangerous hobby because you have no real control over the outcome of a particular game. Sure, you can study statistics and injury reports, but when it all comes down to it, the majority of outcomes are determined solely by chance. Bookies employ groups of people who, for a living, study the odds of every betted game in order to make sure that the bookie will make money. Some people assume that they can guess at the odds better than these hired statisticians, but, in general, it is impossible to improve a bettor’s chances. This is why gambling on sports is almost always a waste of time and money.

Which of the following can be concluded from the paragraph?

Journalist: Choosing a new pope is a difficult decision because the church desires a person who is very experienced in the faith and also someone who can lead the faith well in modern times by being in touch with modern times. The problem is that people who are very experienced in the faith are often very old, and people who are very old tend to be out of touch with modern times, so it appears that there is almost never a pope chosen that fits both criteria. The best decision would be for the church to choose a pope who is young enough to be in touch with modern times and who will likely become a person very experienced in the faith.

Which of the following can be concluded about the journalist’s opinion from the passage?

A park officer reports that in the previous year, 30% of the bear population in the park was determined to be excessively aggressive toward humans. This year, a full 60% of the bear population has been found to beexcessively aggressive. However, bear attack statistics show that in the past 12 months there have been only 3 bear attacks on humans, whereas last year there were 12 such bear attacks over the same time period.

Which of the following would help to resolve the apparent discrepancy present in the passage?

Westerbrook Academy requires the donations of many generous patrons in order to continue operating. Generous patrons need good financial prospects or tax breaks in order to donate to Westerbrook. The government needs a surplus or a negligent executive in order to give tax breaks to people in the economic bracket of Westerbrook’s patrons. The executive of the government is never negligent.

If Westerbrook Academy gets donations and there is no governmental surplus, then which of the following must be assumed?

Political races should be completely subsidized by the government. This would allow for candidates to spend less time fundraising and more time differentiating themselves from their opponents based on substantive issues. It would also free candidates from owing any favors to big corporations once they get into office. When elected under this subsidized system, officeholders would be able to make impartial decisions about corporate acts without feeling as if they had a vested interest in the success of a particular company that had donated large sums of money to their campaign. Fully subsidizing races would equalize the playing field, since every candidate would have an equal amount of money with which to campaign. All these results would greatly improve the political environment of our nation, and in order to enjoy each of these advantages, we only need to lobby the government to completely subsidize political races.

Which of the following principles, if established, provides a basis for supporting the argument above?

Singer: People who listen to music consistently become able to emphatically feel the beat of the world moving around them. They begin to take pleasure in the cosmic pendulum that swings them back and forth through the progression of their days. They learn to appreciate the beginnings and the endings of their spirituality and see where it interfaces with their existence in mortal life. By interpreting and enjoying the movement of songs, a whole new mode of existence is opened up to them.

Pragmatist: The people of whom you speak do tend to be more emphatic and emotional than other people, but the abstract and diverse nature of the effects that you claim are simply impossible to tie to any one cause.

Which of the following is the point at issue between the singer and the pragmatist?

Entomologist: The purple dung beetle has gained its remarkable color through several generations of evolution. Originally, this dung beetle had small, dull, purplish streaks that ran down the length of its dorsal exoskeleton, but some members of the population had more prominent coloring than other beetles. This coloring pattern allowed them to be more noticeable to female beetles roaming through the dung looking for mates. It was so much easier for females to spot vividly striped beetles than beetles of more traditional coloring patterns that the latter were bred out of the gene pool.

Which one of the following, if true, would most support the argument?

The street luge is an extreme sport that combines the basic idea of the Olympic ice luge with wheels and an asphalt hill to roll down. People who engage in luging on ice are subject to very dangerous conditions due to the high speed of their bodies next to areas that are very hard and abrasive. If lugers fall on ice, they get hurt badly, but if street lugers fall, they get hurt even worse. This is because people are able to slide on ice.

Which of the following can be concluded from the passage?

Movie stars fraternize with other movie stars for several reasons. First of all, they meet each other at work on the movie sets. Secondly, they lead similar lives and have similar job paths, so they feel as if they can understand each other. Finally, they associate with each other in hopes of picking up another movie deal through their networking. In conclusion, the social habits of a movie star are complex, but they can be boiled down to the fact that there are numerous positive reasons for a movie star to associate with another movie star.

Which of the following is the main point of the passage?

Protester: Children are taught from birth that fighting and violence toward others is immoral, but even so, it is no small wonder that this peaceful moral imperative is not assimilated by the majority in our nation. As adolescents, children are allowed to watch violent TV shows that feature characters who are idolized solely because of their violent tendencies. As adults, our people are governed by leaders who impose their wholly unprovoked imperialistic tendencies on seemingly peaceful nations. Even though the moral backdrop of our childhoods should bolster a predilection toward peace, the righteous moral framework of our culture is constantly subverted by important role models within our society. Until our role models reform their behavior, our society can never really claim that it promotes peace.

Which one of the following, if true, would most undermine the protester’s argument?

Salespeople are a special breed. They live off their skill at convincing people to part with one of their most prized possessions: money. To do this, salespeople have to be fairly slick, well put together, eloquent, and mentally quick. Otherwise, many buyers would become uninterested in the salespersons’ products and the salespeople would lose business. Some salespeople work on an hourly rate in addition to a commission, but most earn nothing more than a percentage of the price of the products that they sell. Sam the salesman has not sold a product in years, but he still is getting paid. He sells figurines of rabbits for a major pottery maker in West Virginia. The figurines are designed to sit on the desks of salespeople in order to function as good luck charms.

Which of the following is the best inference that you can make from this argument?

In China, side-by-side comparisons between the staple crops of rice and corn reveal that rice always produces more food per cultivated acre than corn can produce. This fact demonstrates that the United States would be best served by switching its agricultural focus from corn to a completely rice-based production scheme that would be sure to provide enough food for our growing population.

Which of the following, if true, would cast doubt on the recommendation in the argument?
