问答题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.
