Answer:
The change Clair should make to correct the punctuation in her sentence is:
1. Insert a semicolon after the word "dark".
Explanation:
"Nevertheless" is a conjunctive adverb joining two independent clauses. When we use conjunctive adverbs, we must add a semicolon before them. That includes "however", "moreover", "therefore", and "consequently", for example. Thus, for Clair's punctuation to be correct, we should add the semicolon after "dark", right before "nevertheless".
