1. 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.

2. Question : <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:
Student Answer: 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.

3. 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.

4. 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.

5. 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.

many of Jamie’s paintings contain no blue at all.
