AWA
Analysis of an Issue: (ex) "People often complain that products are not made to last. They feel that making products that wear-out fairly quickly wastes both natural
and human resources. What they fail to see, however, is that such manufacturing practices keep costs down for the consumer and stimuate demand"
Question: Which do you find more compelling: the complaint about products that do not last or the response to it? Explain your position using relevant reasons and/or
examples from your own experience, observations or readings"
Analysis of an Argument: (ex)" The computerized on-board warning system that will be installed in commercial airliners will virtually solve the problem of midair
plane collisions. One plane's warning system can receive signals from another transponder-a radio set that signals a plane's course-in order to determine the likelihood of
a collision and recommend evasive action
Question: Discuss hwo well reasoned you find this argument. In your discussion, try to analyze the line of reasoning and the use of evidence in the argument. For
example, you may need to consider what questionable asssumptions underlie the thinking and what alternative explanations or counterexamples might weaken the
conclusion. You can also discuss what sort of evidence would strenghten or refute the argument . what changes in the argument woud make it more logically sound, and
what, if anything, would help you to better evaluate the conclusion
