MULTIPLE CHOICE
INSTRUCTIONS: The following selections relate to distinguishing arguments from nonarguments and
identifying conclusions. Select the best answer for each.
1. There appears to be a growing happiness gap between men and women. Women today are working more
and relaxing less, while men are working less and relaxing more. Forty years ago a typical woman spent 40
minutes more per week than the typical man performing an activity considered unpleasant. Today, with men
working less, the gap is 90 minutes and growing.
a. Argument; conclusion: Today ... the gap is 90 minutes and growing.
b. Nonargument.
c. Argument; conclusion: Forty years ago ... an activity considered unpleasant.
d. Argument; conclusion: There appears to be ... between men and women.
e. Argument; conclusion: Women today are working more and relaxing less.
ACCURATE ANSWER: D PTS: 2
2. Lead is toxic, but do you know why? Lead is toxic mainly because it preferentially replaces other metals in
biochemical reactions. In so doing it interferes with the proteins that regulate blood pressure (which can cause
development delays in children and high blood pressure in adults), heme production (which can lead to
anemia), and sperm production. Lead also displaces calcium in the reactions that transmit electrical impulses in
the brain, which diminishes the ability to think and recall information. Anne Marie Helmstine, "Your Guide to
Chemistry"

b. Argument; conclusion: Lead is toxic.
c. Nonargument.
d. Argument; conclusion: It preferentially replaces other metals in biochemical reactions.

, 3. Aristotle focused on clarifying the concept of virtue itself. He argued that it was virtuous to choose the
proper amount of emotion and/or action called for in a particular situation and that extremes of emotion and
action were vices. In all communities there are some men of practical wisdom who have the capacity to judge
wisely. Aristotle argued that they have the capacity to follow the "right rule" whatever the situation.
David Cooper, Value Pluralism and Ethical Choice
a. Argument; conclusion: In all communities ... capacity to judge wisely.
b. Argument; conclusion: Aristotle focused on clarifying the concept of virtue itself.
c. Argument; conclusion: They have the capacity to follow ... the situation.
d. Argument; conclusion: He argued that it was virtuous ... were vices
e. Nonargument.
ACCURATE ANSWER: E PTS: 2
4. Illegal immigrants pay local sales taxes, and many of them also pay state, local, and federal income tax and
Social Security tax. They also purchase items from local merchants, increasing the amount these merchants
pay in taxes. In addition, they work for low salaries, which increases the earnings of their employers and the
amount of taxes these employers pay. Thus, it is not correct to say that illegal immigrants contribute nothing to
the communities in which they live.
a. Argument; conclusion: It is not correct to say ... communities in which they live.
b. Argument; conclusion: They work for low salaries ... these employers pay.
c. Argument; conclusion: Illegal immigrants pay ... Social Security tax.
d. Argument; conclusion: They also purchase items ... pay in taxes.
e. Nonargument.
ACCURATE ANSWER: A PTS: 2
5. Numerous studies have indicated that women of color, black women in particular, are over-arrested, over-
indicted, and over-sentenced. African-American women are seven times more likely to be arrested for
prostitution than women of other ethnic groups. Black women have received significantly longer sentences for
crimes against property and served longer periods in prison. For both murder and drug offenses, Euroamerican
women ended up serving one-third less time for the same offenses than black women.
Nancy Kurshan, "Women and Imprisonment in the U.S."
a. Argument; conclusion: African-American women ... other ethnic groups.
b. Nonargument.
St
c. Argument; conclusion: For both murder and drug offenses ... black women.
d. Argument; conclusion: Numerous studies have indicated ... over-sentenced.
