Question 5. 5. <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 (Points : 1) |
[removed] Jerry with other members of the team
[removed] the members of one team with the members of another team
[removed] people who are six feet three inches tall for people who are exactly six feet tall
[removed] an average for the individuals that make up that average.

Question 6. 6. <11{1[4(17)17]}> 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: (Points : 1) |
[removed] more students in the morning class may have passed the test than failed the test.
[removed] some students may have been absent from both classes.
[removed] some of the students who passed the afternoon test may have received information about the test from morning students.
[removed] more students may have taken the test in the afternoon than in the morning. |
Question 7. 7. <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? (Points : 1) |
[removed] Some forms of art making are expensive and require a good deal of money to pursue.
[removed] Many people who aren’t artists prefer to pursue practical and safe careers.
[removed] Having the time and money to make art doesn’t guarantee an artist commercial success.
[removed] Splitting time between two pursuits in life often causes both to suffer. |
Question 8. 8. <21{2[1(01)25]}> The untimely death of Professor Hathaway halted his groundbreaking research into the uses of solar power. It therefore appears that Hathaway’s research will not result in practical applications.
Which one of the following, if true, most seriously weakens the argument? (Points : 1) |
[removed] Professor Hathaway’s research can be used by other scientists to create useful applications.
[removed] Not all professors at Professor Hathaway’s university knew that he was conducting research into the uses of solar power.
[removed] Officials at Professor Hathaway’s university have refused requests to make Professor Hathaway’s research public.
[removed] Researchers at other universities are conducting research into the potential applications of solar power. |
Question 9. 9. <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? (Points : 1) |
[removed] Some of the politicians try to hide the fact that they travel by private plane to their speeches around the country.
[removed] Most people who hear the politicians’ speeches on the environment are unconvinced by their arguments.
[removed] A majority of voters surveyed agree that politicians sometimes make society’s problems worse.
[removed] 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. |
