Try working with the second blank first. The clue is “none of the family members were fearful…of appearing or acting differently from other people.” Therefore, find a word for the second blank that means uniqueness. Eccentricity fits the bill. Considering the clue, “The Johnson’s were not known for their,” the two blanks must be opposites. Eliminate candor and vulgarity based on the clue and the word choice for the second blank, and choose conformity.
