孙远GMAT作文讲义（一）

　　The computerized onboard warning system that will be installed in commercial airliners will virtually solve the problem of midair plane collisions. One planes warning system can receive signals from anothers transponder--a radio set that signals a planes 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.

　　This argument has no information about air collisions. I think most cases happen is new airports because the air traffic is heavy. In this case sound airport control could solve the problem.

　　I think this argument is logically reasonable. Its assumption is that plane collisions are caused by planes that dont know each others positions. So pilots can do nothing, if they know each others position through the system it will solve the problem. If it can provide evidence the problem is lack of knowledge of each others positions, it will be more sound and persuasive.
