Hello,

I picked (D) initially but then was able to chose (B) as the correct answer. But I had trouble identifying the flawed reasoning in the stimulus. I was wondering if the stimulus and (B) had the the same flaw, because they assume if C (burning fossil fuels) can benefit/cause D (rising carbon dioxide), then nothing harmful can come from A and A should be promoted.

Could you explain the stimulus and analyze the answer choices for me?

Thank you so much!

You bet, lilmissunshine! (Btw, I've seen the yellow microbus from that movie up close in person - it's at the Petersen Automotive Museum in L.A.)

I see the flaw in this argument as being a particular type of evidence flaw, one we usually refer to as a "some evidence" flaw. Here, some evidence that CO2 is good is taken as proof that it is purely good. That's what I used to compare my answer choices.

Answer A: the conclusion is that one thing would be better than another, not that one thing is purely good. Loser.

Answer B: Exercise is good, so it must be purely good. Winner!

Answer C: One thing causes a problem, so if you want to avoid that problem do something else. Not at all a match, so Loser.

Answer D: The conclusion here makes a recommendation to do something (one ought to do X) and stop doing another (abandon Y), but our stimulus made no such recommendation. Loser.

Answer E: Excessive use is bad, so a recommendation is to cease all use. Again, our stimulus made no recommendation, plus this one has no element of "good therefore purely good". Loser.

I hope that helps!

Thanks a lot Adam! That was very helpful. :)

P.S. I love that movie! I should've checked it out in LA when I was there a couple of weeks ago...
