1. A recent study of 100 employees from six departments of a major corporation found 65% to be sleep deprived. The researchers concluded that the majority of corporate employees are sleep deprived.
The researcher's conclusion is suspect because it:
• assumes that corporate employees are more sleep deprived than other people.
• is based on evidence that is statistically impossible.
• fails to describe the effects the sleep deprivation has.
• relies on a sample that is too small to represent the entire corporate workforce.

2. Since Jessica's participation in local politics increased significantly after she joined her school's political science club, it is clear that her involvement in that club led her to take an interest in politics.
The argument above is flawed because:
• it doesn't say which political issues Jessica is interested in.
• it states that the only purpose of the political science club is to spark an interest in politics.
• it misuses the word "significantly."
• it's possible that an interest in politics caused Jessica to join the political science club.

3. People have claimed that Jamie's paintings have given them the blues. Clearly this cannot be entirely correct, since many of Jamie's paintings contain no blue at all.
The argument above is flawed because the author:
• provides no evidence.
• misinterprets a key term.
• relies on contradictory facts.
• is not a noted painting expert.

4. The average height of members of the high school basketball team is six feet, three inches. Jerry is on the high school basketball team, so Jerry must be taller than six feet.
The argument above is flawed because it confuses
• Jerry with other members of the team
• the members of one team with the members of another team
• people who are six feet three inches tall for people who are exactly six feet tall
• an average for the individuals that make up that average.

5. Catherine goes to her local movie theater only to see romantic comedies. Since Catherine did not go to the movies yesterday, there is not a romantic comedy playing at her local theater.
The reasoning above is flawed because the evidence:
• does not suggest that Catherine goes to see every romantic comedy that plays at her local movie theater.
• implies that Catherine is uninterested in most types of movies.
• does not indicate whether Catherine watches only romantic comedies at home.
• suggests that Catherine's local movie theater hardly ever shows romantic comedies.

6. Mrs. Orlof teaches two history classes, one in the morning and one in the afternoon. Yesterday she gave the same test to both classes. Anyone who failed the test must take a retest. Since a greater percentage of students who took the morning test failed the test than students who took the afternoon test, more of Orlof's morning history students than afternoon history students will have to take the retest.
The conclusion above is not necessarily valid because:
• more students in the morning class may have passed the test than failed the test.
• some students may have been absent from both classes.
• some of the students who passed the afternoon test may have received information about the test from morning students.
• more students may have taken the test in the afternoon than in the morning.

7.Aron: The two double A batteries in my CD player are dead, so the CD player doesn't work. My television remote control, which also uses two double A batteries, works fine. So if I move the two batteries from my television remote control to my CD player, the CD player will definitely work.
Aron's argument is most strengthened if which one of the following is true?
• Aron inserted the current batteries in his television remote control two months before he inserted the current batteries in his CD player.
• The amount of energy required to power the CD player is not greater than the amount of energy needed to power the television remote control.
• Aron has used his television remote control more times than he has used his CD player since inserting the current batteries into each device.
• Double A batteries provide less energy than either C batteries or D batteries.

 8. Career counselor: It is best for artists to build a practical and safe career that will guarantee them a secure income, and then pursue their art in their spare time. That way, they will be motivated to work hard at their day jobs to support their art making, and both their career and their art will thrive.
Which one of the following, if true, would most weaken the argument?
• Some forms of art making are expensive and require a good deal of money to pursue.
• Many people who aren't artists prefer to pursue practical and safe careers.
• Having the time and money to make art doesn't guarantee an artist commercial success.
• Splitting time between two pursuits in life often causes both to suffer.

9. Some politicians claim to support the environment in speeches they make around the country. However, to get to those speeches they ride in gas guzzling, pollution creating private planes. They therefore clearly don't believe a word of what they say and are actually making the environmental problem worse.
Which one of the following, if true, would best weaken the argument above?
• Some of the politicians try to hide the fact that they travel by private plane to their speeches around the country.
• Most people who hear the politicians' speeches on the environment are unconvinced by their arguments.
• A majority of voters surveyed agree that politicians sometimes make society's problems worse.
• Improvements to the environment brought about through the politicians' public support of environmental regulations more than offset the damage done to the environment by the politicians' private planes.

10.As part of its reorganization, company X created five new positions within the company. However, after the reorganization was complete, company X had fewer employees than before the reorganization.
Which one of the following, if true, would best explain the result described above?
• Some employees of the company were switched into new departments to fill the new positions.
• Some employees who quit over dissatisfaction with the reorganization were immediately replaced by new hires.
• The new positions were created to respond to a greater demand for company X's products.
• Some employees were laid off as a number of old positions were eliminated in the reorganization.

11. Surveys show that people who use calorie information to decide which foods to eat consume on average 100 calories less than they would if they didn't check calorie information before eating. Strangely though, people who use calorie information in this way weigh more on average than people who don't check calorie information before eating.
Which one of the following, if true, best explains the surprising statistic stated above?
• There are fewer people who check calorie information before eating than people who don't check calorie information before eating.
• People who usually check calorie information before eating consume more calories if they stop checking.
• Some people who check calorie information before eating don't consume any fewer calories than they would if they didn't check.
• People with a weight problem are most likely to check calorie information before eating.

15. Arthur: The solutions to most mystery novels I read are not believable. However, my enjoyment of a mystery novel depends only on its suspenseful mood and colorful characters.
Norton: Roughly 80% of the mystery novels I read have believable solutions, which is good since I do not enjoy mystery novels that don't have believable solutions.
The speakers above:
• agree that most mystery novels do not have believable solutions.
• agree that a suspenseful mood and colorful characters add to the enjoyment of a mystery novel.
• disagree on whether a believable solution is required for the enjoyment of a mystery novel.
• disagree on whether an author's enjoyment in creating a mystery novel influences whether that novel will have a believable solution.

16. Memmie: The greater the population near a restaurant, the more potential customers it has and the greater chance its popularity will spread through word-of-mouth. O'Sullivans Restaurant just opened in the very densely populated town of Redville, so its chances for success are great.
Sam: But the more people living in an area, the more restaurants there are in that area, so the more competition each one faces. There are twelve other restaurants serving the people of Redville.
Memmie and Sam seem to disagree about whether:
• O'Sullivans will fail in its first few months.
• O'Sullivans will serve a different kind of food than the other restaurants in Redville.
• the high population of Redville ensures that O'Sullivan's has a great chance for success.
• word-of-mouth about a restaurant can spread in a densely populated town like Redville.

17. Some drugs combat obesity or alcohol addiction by turning off pleasure centers in the brain. However, if the dosage is too high, there's a risk that people taking them will be plunged into depression.
The statements above, if true, support which one of the following assertions?
• It is useless to try to treat obesity or alcohol addiction through drugs.
• All drugs, if taken at too high a dosage, pose the risk that the people taking them will be plunged into depression.
• The benefits of a medication may be at least somewhat offset by its side effects.
• Drugs that affect pleasure centers in the brain are often taken at dosages considered to be too high.

18. Only circus animals with a clean bill of health will perform in today's exhibition. A monkey, a poodle, and a horse will perform in today's exhibition. No circus animals with a clean bill of health were prescribed medications this week.
If the statements above are true, which one of the following must also be true on the basis of them?
• The monkey, poodle, and horse are the only animals performing in today's circus exhibition.
• No circus animals were prescribed medications this week.
• No more than two circus animals have a clean bill of health.
• Neither the monkey nor the horse performing in today's circus exhibition were prescribed medications this week.

19. In a survey of 10 film historians, half voted for Nosferatu as the greatest vampire film ever made, and the other half voted for Dracula. However, when asked which lead vampire character they considered more charismatic, all of the film critics chose Dracula over Nosferatu.
Based on the information above, it must be true that for some film critics, their feelings about the charisma of the lead character:
• is the least important factor they consider when comparing two films.
• is the most important factor they consider when comparing two films.
• is not the most important factor they consider when comparing two films.
• is the only factor they consider when comparing two films.

20. A company can either invest in employee training seminars or update its computer network. Since updating the computer network would result in more measurable benefits, the company would be best off updating its computer network.
The argument above assumes that:
• investing in employee training seminars would yield negative results for the company.
• the more measurable a benefit, the greater value that benefit has to a company.
• the employee training seminars would focus on teaching employees to use the updated computer network.
• the benefit of the company investing in employee training seminars cannot be measured at all.

21. Detective: The robbery at the mall was carried out by a mall employee acting alone roughly one hour after the mall closed last Saturday night. The only employees present at the mall at the time of the robbery were security guards Evans and Clark. Since the mall's surveillance system was disabled by the thief just before the robbery, the thief must be Evans.
The argument above would be valid if:
• Clark is incapable of disabling the mall's surveillance system.
• both Evans and Clark are capable of disabling the mall's surveillance system.
• Evans and Clark are the mall's only security guards.
• the mall's surveillance system is usually used 24 hours a day, seven days a week.

22. Looking to increase the profits of his lemonade stand, Johann doubled the price of a cup of lemonade from 25 cents to 50 cents. This clearly shows Johann's lack of business sense, for now he'll almost certainly sell fewer cups at the new price and therefore make less money than before.
The argument above assumes that:
• Johann is looking to double the profits of his lemonade stand.
• the price increase will likely put Johann out of business.
• profits from the price increase will not offset the money lost when fewer cups are sold.
• even if Johann sells more cups at the new price than he did at the old price, he'll still lose money on the lemonade stand.

23. Sometimes people get caught in a "downward spiral," a case in which something leads to a result which in turn leads to more of the original thing, bringing on more of the result. As the process continues, the result continually gets worse and worse. An example is when people turn to binge eating when depressed, which causes them to put on weight and feel unhealthy, which then makes them more depressed, leading to more overeating, and so on.
The author is mainly concerned with:
• convincing people not to overeat.
• explaining the process of the "downward spiral."
• showing how overeating can lead to depression.
• showing how some processes lead to surprising results.

24. The very large increase in allergies over the last thirty years is due to the great success of immunizations administered over this time period. Since immunizations have nearly eliminated life-threatening diseases such as polio, the human immune system increasingly targets other environmental substances in order to keep working properly. Allergy symptoms such as runny nose and itchy eyes result when the immune system attacks pollen that is breathed in from the air.
Which one of the following best expresses the main point of the passage above?
• Immunizations often have surprising side effects.
• Immunizations have been very successful in eliminating life-threatening diseases.
• Viruses that once caused polio now cause allergies.
• The use of immunizations has led to an increase in allergies.

25. Whereas many industries suffer during economic recessions, the art industry does well. Some think the reason is that artists feed off the anxiety and uncertainty during recessions to produce inspired works. Others think that recessions, while harmful to most people, produce a handful of very rich people willing to pay very high prices for artworks, driving up the value of the art market as a whole.
The author of the passage above is primarily interested in:
• providing evidence that the art industry does well during recessions.
• presenting reasons for why the art industry does well during recessions.
• discussing the types of artworks that sell best during recessions.
• describing the effect that art has on the economy.
