Hi Shannon!
I certainly understand your frustrations with the Engineer's argument--it's not a great one! Unfortunately, most arguments on the LSAT are not very good. They often have gaps, inconsistencies, false assumptions, etc. But LSAT authors always think they've provided us a perfect, logically sound argument. Our task is to try to understand the author's argument as stated, while recognizing where the author may have gone wrong.
I think that's the piece missing from your current analysis: you need to focus on the argument structure. These aren't 2 totally disconnected sentences or simply 2 examples. The author is presenting an argument. The author's conclusion is the 2nd sentence: that a technical fix to slow or reverse global warming would encourage more carbon dioxide emissions, possibly causing more global warming in the future. What evidence does the author give us to believe this? He uses an analogy and compares slowing global warming to driving on a wide road free of obstruction. His reasoning is that these are similar cases (he uses the term "Likewise"), so if driving on a road free of obstructions encourages risky driving, slowing global warming would encourage risky behavior involving carbon dioxide emissions.
I agree that this is not a great argument. Analogies only work if you are comparing 2 actually similar cases and a wide road free of obstructions doesn't seem to have much in common with a technical fix for global warming. But we're not being asked to identify the flaw in this argument, to attack the argument, or even to fix the argument. Instead, we're being asked what principle the argument is invoking. So we need to understand the argument as the author has written it so that we can determine what principle he is using. The author thinks that these 2 cases are similar. He thinks increasing carbon dioxide emissions is akin to risk-taking while driving. It doesn't matter whether we agree that these are similar instances. We're essentially just describing the principle underlying the argument without passing any judgment on that argument.
(Note: Though the accuracy of the analogy is irrelevant when we're just describing the principle of the argument, an argument could be made that increasing carbon emissions is a type of risky behavior because it's a behavior that could have negative consequences. These consequences may not be as immediate as the consequences that could result from risky driving, but that's likely why the author is using an analogy in the first place: to make issues about global warming seem more concrete.)
Answer choices (C) and (D) do not describe the principle underlying this argument. Again, this argument relies solely on an analogy. So the principle has to deal with the connection between the two cases that the author is trying to make. He is not trying to connect these cases with the idea that technical fixes are temporary or with the idea that technical fixes cannot discourage risk-taking behavior. He is trying to connect them with the idea that creating a feeling of security (with wide roads free of obstruction or technical fixes for global warming) encourage risk taking (in drivers and in activities involving carbon dioxide emissions).
Hope this helps!
Best,
Kelsey
