Hi, I had a grammar question from a research paper I just got back. Here is the sentence in question: "As a result, since these are definite measurable concepts, so too must seemingly esoteric concepts like timbre." My professor (not an English professor) said I needed a verb in the second half of the sentence. But is that true? I was sure I could format the sentence in that way so that the second half uses the verb "are" from the first half. I can't find any source supporting that, though. Could anyone help me out, and if so, give me a concrete source on why it works (or not)? Thanks!

Yes, you need a verb at least. 'Must', the auxiliary, does not work with 'are'. As a result, since these are definite measurable concepts, so too must be seemingly esoteric concepts like timbre.
