INSTRUCTIONS: Thee following selections relate to distinguishing arguments from nonarguments and h h h h h h h h h h h
identifying conclusions. Select the best answer for each. h h h h h h h
1. There appears to be a growing happiness gap between men and women. Women today are working mor
h h h h h h h h h h h h h h h h
e and relaxing less, while men are working less and relaxing more. Forty years ago a typical woman spe

nt 40 minutes more per week than the typical man performing an activity considered unpleasant. Today
h h h h h h h h h h h h h h h
, 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
h h h h h h h h h h h h h h h h h h
biochemical reactions. In so doing it interferes with the proteins that regulate blood pressure (which can ca
h h h h h h h h h h h h h h h h h
use development delays in children and high blood pressure in adults), heme production (which can lead t
h h h h h h h h h h h h h h h h
o anemia), and sperm production. Lead also displaces calcium in the reactions that transmit electrical imp
h h h h h h h h h h h h h h h
ulses in the brain, which diminishes the ability to think and recall information.

3. Aristotle focused on clarifying the concept of virtue itself. He argued that it was virtuous to choose the prop
h h h h h h h h h h h h h h h h h h
er amount of emotion and/or action called for in a particular situation and that extremes of emotion and acti
h h h h h h h h h h h h h h h h h h
on were vices. In all communities there are some men of practical wisdom who have the capacity to judge
h h h h h h h h h h h h h h h h h h h
wisely. Aristotle argued that they have the capacity to follow the "right rule" whatever the situation.

4. Illegal immigrants pay local sales taxes, and many of them also pay state, local, and federal income tax and
h h h h h h h h h h h h h h h h h h h
Social Security tax. They also purchase items from local merchants, increasing the amount these merchant
h h h h h h h h h h h h h h
s pay in taxes. In addition, they work for low salaries, which increases the earnings of their employers and t
h h h h h h h h h h h h h h h h h h h
he amount of taxes these employers pay. Thus, it is not correct to say that illegal immigrants contribute noth
h h h h h h h h h h h h h h h h h h
ing to the communities in which they live.

a. Argument; conclusion: It is not correct to say ... communities in which they live.h h h h h h h h h h h h h

5. Numerous studies have indicated that women of color, black women in particular, are over-
h h h h h h h h h h h h h
arrested, over-indicted, and over-sentenced. African-
h h h h
American women are seven times more likely to be arrested for prostitution than women of other ethnic gr
h h h h h h h h h h h h h h h h h
oups. Black women have received significantly longer sentences for crimes against property and served lo
h h h h h h h h h h h h h h
nger periods in prison. For both murder and drug offenses, Euroamerican women ended up serving one-
h h h h h h h h h h h h h h h
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 elem
h h h h h h h h h h h h h h h h h
ents lurking in the shadows of cyberspace who send out probes to detect unprotected PCs. Once a vulnerabl
h h h h h h h h h h h h h h h h h

ing stolen IDs. They also defraud online advertisers by using these zombie computers to visit pay-per-

click ads. h

7. The earth is of interest to astronomy for many reasons. Nearly all observations must be made through the at
h h h h h h h h h h h h h h h h h h
mosphere, and the phenomena of the upper atmosphere and the magnetosphere reflect the state of interplan
h h h h h h h h h h h h h h h
etary space. The earth is also the most important object of comparison for planetologists.

9. Humans are biological organisms. To understand our behavior and mental processes, we need to understa
h h h h h h h h h h h h h h
nd their biological underpinnings, starting with the cellular level, the neuron. How we feel, learn, rememb
h h h h h h h h h h h h h h h
er, and think all stem from neuronal activity. So, how a neuron works and how neurons communicate are c
h h h h h h h h h h h h h h h h h h
rucial pieces of information in solving the puzzle of human behavior and mental processing.

10. Viruses are acellular entities too small to be seen with a light microscope. They are composed of a nucleic
h h h h h h h h h h h h h h h h h h h
acid and a few proteins. Viruses replicate themselves and display other properties of living organisms only
h h h h h h h h h h h h h h h
when they have invaded living cells. Indeed, some viruses can be crystallized and stored in a container on
h h h h h h h h h h h h h h h h h h h
a shelf for years, but they retain the capacity to invade cells and cause disease.

12. It is likely that innocent prisoners in this country have been executed for crimes they did not commit. From
h h h h h h h h h h h h h h h h h h h
1973 until 2007, 124 death row inmates have been exonerated. In many of these cases DNA evidence playe
