Question

frank shrugged ____ saying, \im not sure what i want to do after i graduate.\
indifferently
eternal
reassure
nocturnal

the line at disneyland seemed almost ____, but the friends finally reached the front.
indifferently
eternal
petrified
nocturnal

write a completely grammatical sentence with 1 of the words below:
reassure
accompany

Explanation:

For the first sentence, "shrugged" is a verb and needs an adverb to modify it. "Indifferently" is an adverb meaning without interest or concern. "Eternal" (adjective), "reassure" (verb), and "nocturnal" (adjective) do not fit grammatically.
For the second sentence, "seemed" is a linking verb and needs an adjective. "Eternal" (adjective) meaning without end fits as the line at Disneyland seemed very long (almost without end). "Indifferently" (adverb), "petrified" (usually means turned to stone or very frightened, not fitting here), and "nocturnal" (related to night) do not fit.

Answer:

First question: Indifferently
Second question: Eternal
