A vs D

Hello, I was so torn between A and D. A makes sense because the craft was being flown for "good" reasons in comparison to a factory. However, I feel like A can also infer that this craft is only being used once or handful of times a year whereas a factory is being used every single day. That said, this led me to hone in D because of the aforementioned reasons of A, D would be the answer because these two quantities of pollution between craft and factory are incomparable?

Hi @cheynnelee,

Thanks for the question! (D) is wrong because it’s too strongly worded. the environment doesn’t say they’re not comparable IN ANY WAY. It just says that there’s one main difference.

Hope this helps! Feel free to ask any other questions that you might have.
