Question

complete the sentence. braden knew that he had heard the word auspicious before and vaguely understood the meaning, but he could neither think of a synonym nor. could he use the word in a sentence. use the word in a sentence

Explanation:

The structure "neither...nor..." requires parallelism. The first part is "think of a synonym" (verb phrase), so the second part should also be a verb phrase. "Could he use the word in a sentence" is an inverted structure (due to the negative 'neither...nor...' construction), but the correct parallel form is "use the word in a sentence" (verb phrase to match "think of a synonym").

Answer:

use the word in a sentence
