I am reading Thomas Merton's famous autobiography, The Seven Storey Mountain, and was reminded yesterday of this thread, when, in reading the book, I came upon another rare instance of a correlative comparative containing inversion in the second clause.
This example more closely resembles Novice's (c) than does the Uncle Tom's Cabin example I gave above, since the clause in question uses "be," it contains "the more," and "the more" modifies an adjective. Actually, "the more" modifies three coordinated adjectives. Enjoy!
"The more active Pop became and the more he shouted and gave directions, the more hesitant and doubtful and finally inert was my grandmother."
