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.

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 Helmenstine, "Your Guide to Chemistry"
a. Argument; conclusion: It interferes with the proteins ... and sperm production.
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.

4. Undocumented 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 undocumented immigrants contribute nothing to the communities in
which they live.

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.

6. It's even more important these days that your computer be protected by a firewall. There are criminal elements lurking
in the shadows of cyberspace who send out probes to detect unprotected PCs. Once a vulnerable computer is found, these
criminals install software that assists them in committing identity theft and fencing stolen IDs. They also defraud online
advertisers by using these zombie computers to visit pay-per-click ads.

e. Argument; conclusion: It's even more important ... protected by a firewall.
ANSWER: e
7. The earth is of interest to astronomy for many reasons. Nearly all observations must be made through the atmosphere,
and the phenomena of the upper atmosphere and the magnetosphere reflect the state of interplanetary space. The earth is
also the most important object of comparison for planetologists.
Hannu Karttunen, et al., Fundamental Astronomy
a. Argument; conclusion: The phenomena ... state of interplanetary space.
b. Argument; conclusion: The earth is also ... for planetologists.

8. If the trade in tiger products is banned, tiger reserves are guarded by well equipped staff, communities abutting tiger

9. Humans are biological organisms. To understand our behavior and mental processes, we need to understand their
biological underpinnings, starting with the cellular level, the neuron. How we feel, learn, remember, and think all stem
from neuronal activity. So, how a neuron works and how neurons communicate are crucial pieces of information in
solving the puzzle of human behavior and mental processing.
Richard Griggs, Psychology: A Concise Introduction
a. Argument; conclusion: To understand our behavior ... the neuron.
b. Argument; conclusion: Humans are biological organisms.
c. Argument; conclusion: How we feel ... neuronal activity.
d. Argument; conclusion: How a neuron works ... mental processing.
e. Nonargument.
ANSWER: d
10. Viruses are acellular entities too small to be seen with a light microscope. They are composed of a nucleic acid and a
few proteins. Viruses replicate themselves and display other properties of living organisms only when they have invaded
living cells. Indeed, some viruses can be crystallized and stored in a container on a shelf for years, but they retain the
capacity to invade cells and cause disease.
Jacquelyn C. Black, Microbiology: Principles and Explorations
a. Argument; conclusion: They are composed of a nucleic acid and a few proteins.
b. Nonargument.
c. Argument; conclusion: Viruses are acellular entities ... microscope.
d. Argument; conclusion: Indeed, some viruses can be crystallized ... cause disease.

11. Harnessing the clean, abundant energy of the sun and wind is critical to solving the global warming problem.
Technological advances have brought the cost of electricity generated by the wind down by 82 percent since 1981. Solar
energy technology has made remarkable progress as new photovoltaic cells have been developed to convert even greater
amounts of sunlight directly into electricity. Today the costs of wind and solar power are becoming competitive with dirty
coal-fired plants.
Sierra Club, "Global Warming Solutions"
a. Argument; conclusion: Today the costs of wind ... dirty coal-fired plants.
b. Argument; conclusion: Technological advances ... by 82 percent since 1981.
c. Argument; conclusion: Harnessing the clean ... the global warming problem.
