The Analytical Writing Assessment (AWA) consists of one 30-minute writing task called the Analysis of an Argument. In this section, you must read a brief argument, analyze the reasoning behind it, and then write a critique of the argument.
The following appeared as part of an article in a daily newspaper：
"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’s transponder—a radio set that signals a plane’s course—in order to determine the likelihood of a collision and recommend evasive action. "
Discuss how well reasoned you find this argument. In your discussion, be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it more logically sound, and what, if anything, would help you better evaluate its conclusion.
Merely based on unfounded assumptions and dubious (suspicious) evidence, the statement draws a conclusion that_____. To substantiate (support) the conclusion, the arguer points out evidence that_____. In addition, he indicates that_____. (Furthermore, he cites the result of a survey in support of his recommendation). At first glance, the author’s argument appears to be convincing, but further reflection reveals that it omits some essential concerns that should be addressed to substantiate the argument. From my point of view, this argument suffers from 2/3 major logical flaws.
To sum up, this arguer fails to substantiate his claim that_____, because the evidence cited in the analysis does not lend strong support to what the arguer maintains. Therefore, if the argument had included the given factors discussed above, it would have been more thorough and logically acceptable.
