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?

Interested! Thank you so much for doing this!
