why is E incorrect? i know that the author regards Drescher's view as incomplete because he fails to explain why antislavery activism could be so popular in England, but i think "superficially convincing" matches his attitude since at the beginning of second paragraph, the author introduces Drescher's view as "more balanced." So i thought he introduces Drescher's view as "more balanced", but finally criticizes it as "superficially convincing".
i don't understand why "unrealistic" is a better description here.
Thanks a lot!
