just memorize this as a 2-piece parallelism signal. unlike most parallelism signals, though, it requires an independent clause after each part (a relatively unusual construction).
i've always hated this construction, because the more concise "just as ... [nothing] ..." - i.e., the same construction, without the "so" - is also idiomatic. therefore, the "so", in my opinion, is pointlessly wordy, unless it relieves the sentence of some ambiguity.
note that (b), which ostensibly uses the more concise construction, is ungrammatical: "an archaeologist who needs a background in art history to evaluate finds of ancient art" is a sentence fragment. it's a subject + modifier, and doesn't have a verb.
[I highlighted "is ungrammatical" above]
Is (B) ungrammatical because it is not logically parallel?
I understand that "an archaeologist who ... ancient art" is a sentence fragment. But I believe the entire sentence ("Just as an archaeologist who ...ancient art, a nautical archaeologist ... understand shipwrecks") as such is a complete sentence and not a fragment. So why is (B) ungrammatical? is it because it is not parallel?
I believe "As" can act as a preposition, in which it is followed by a noun rather than a clause. For example,
- As a child, I thought I could fly. Or
- As your leader, I am in charge.
Can we treat the use of "as" in (B) as preposition mentioned in above examples?
