Before I answer, I just want to make sure you're asking about (A) and (B) for 73.2.20—is that correct?

I still sense there is another flaw in this argument: the author assumes that Green-manure crop is the only way to improve the soil structure.
This assumption plus the one mentioned in answer choice E leads to the conclusion that, if people want to improve soil structure, farmers have to abandon fertilizers.
Please let me know if I think correctly. Thanks.
