1. Question : 21{1[1(13)13]} 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 Student Answer: 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 Points Received: 1 of 1 Comments: 2. Question : 21{1[1(01)01]} 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 Student Answer: 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 Points Received: 1 of 1 Comments: 3. Question : 11{1[3(02)02]} 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 Student Answer: 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 Points Received: 1 of 1 Comments: 4. Question : 11{1[4(23)23]} 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 Student Answer: provides no evidence misinterprets a key term relies on contradictory facts is not a noted painting expert Points Received: 1 of 1 Comments: 5. Question : 21{1[2(24)24]} 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 Student Answer: 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.

Which one of the following points out the flaw in the argument above? Student Answer: Just because Dasha is a sage doesn’t mean that she is always wise and inspirational. Just because Dasha’s speech provided wisdom and inspiration doesn’t mean that it provided more wisdom than inspiration. Just because Dasha satisfied two requirements of being a sage doesn’t necessarily mean that she satisfies all the requirements of being a sage. Just because Dasha provided wisdom and inspiration in a speech doesn’t mean that all sages use speeches to provide wisdom and inspiration. Points Received: 1 of 1 Comments: 7. Question : 11{2[3(02)26]} 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? Student Answer: 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. Points Received: 1 of 1 Comments: 8. Question : 21{2[2(12)36]} 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? Student Answer: 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. Points Received: 1 of 1 Comments: 9. Question : 11{2[3(11)35]} 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? Student Answer: 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.

However, opera Y generated far greater net profits for City Opera House than did opera X. Each of the following could directly explain the result indicated above EXCEPT: Student Answer: a difference in the ticket prices of operas X and Y a difference in the operating expenses of operas X and Y a difference in the subject matters of operas X and Y a difference in the merchandise sales associated with operas X and Y Points Received: 1 of 1 Comments: 11. Question : 21{3[2(08)44]} 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? Student Answer: 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. Points Received: 1 of 1 Comments: 12.

Question : 11{5[1(05)61]} 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 Student Answer: 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 O’Sullivan’s a great chance for success word-of-mouth about a restaurant can spread in a densely populated town like Redville Points Received: 1 of 1 Comments: 16. Question : 21{5[1(03)59]} Barney: Last winter, I slipped on the outside stairs of PineTree Café and broke my leg. My fall was caused by ice on the stairs that the restaurant failed to remove. Since the restaurant clearly did not provide a safe atmosphere for its customers, I am justified in taking it to court. Lydia: Unwarranted lawsuits are sweeping the country—lawsuits that have no legal merit and are brought simply to make lawyers and their clients rich. If this trend continues, soon our legal system will be swamped to the point where it won’t be able to administer justice to people who truly deserve it. You therefore should drop your case against PineTree Café. The speakers above appear to disagree on which one of the following points? Student Answer: Barney is likely to win his case against Pinetree Café. Barney’s lawsuit against Pinetree Café is unwarranted. Many unwarranted lawsuits are sweeping the country. The legal system will soon be unable to administer justice to people who deserve it. Points Received: 1 of 1 Comments: 17. Question : 7{6[3(02)66]} 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 Student Answer: 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 Points Received: 1 of 1 Comments: 18. Question : 11{6[1(07)71]} The higher the price of an antique, the greater people’s expectation that the object is rare. That, in turn, makes the antique appear more valuable. If the statements above are correct, then offering an antique for sale at a bargain price Student Answer: will likely increase people’s expectations that the antique is valuable will guarantee that the antique will not sell at a profit should be encouraged because it increases the likelihood that antique will be sold should be discouraged because it lessens a quality that makes that antique desirable Points Received: 1 of 1 Comments: 19. Question : 21{6[3(08)72]} 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? Student Answer: 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. Points Received: 0 of 1 Comments: 20. Question : 11{7[3(08)84]} The president spoke to 19 congressmen from Texas to encourage them to vote for a bill. Since four of the 19 congressmen went on to vote for the bill, it is clear that the president persuaded those four to vote the way they did. The argument above assumes that Student Answer: the bill will not pass because a majority of Texas congressmen did not vote for it the Texas congressmen who voted against the bill were persuaded by someone other than the president to vote the way they did the president did not try to influence the votes of any congressmen outside of Texas the four Texas congressmen who voted for the bill were against it before they spoke to the president Points Received: 1 of 1 Comments: 21. Question : 11{7[2(03)79]} 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 Student Answer: 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 Points Received: 1 of 1 Comments: 22. Question : 11{7[1(01)77]} 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 Student Answer: 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 Points Received: 1 of 1 Comments: 23. Question : 11{8[1(10)98]} 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 Student Answer: 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 Points Received: 1 of 1 Comments: 24. Question : 11{8[1(04)92]} 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? Student Answer: 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.

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 Student Answer: 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 Points Received: 1 of 1 Comments:
