Interested! Thank you so much for doing this!

Ok I was so careless to choose the wrong answer on this one. I chose E because I thought E says gasoline adds no more CO to the atm than plants can absorb. Just out of curiosity tho, if E actually says NO more, would the answer choice be E then?

I did the question wrong because I misidentified the conclusion. Originally I thought the sentence “ these emergencies could be avoided....” as the conclusion. After JY’s explanation I started to see the correct conclusion, but in my mind I still think the 2nd sentence could be the conclusion. It feels more like an author’s opinion rather than context which normally contains only factual statement. I feel that even I come across the question again, I still won’t identify the conclusion correctly. Does anyone have the same confusion or any tips of how to analyze this type of argument?
