ExplanationThe word belied indicates a contrast between the current state of the administration, halcyon days, and the president’s journey to the White House. Therefore, the missing words must mean the opposite of peaceful or calm; you need a word such as rough or chaotic. Eliminate
choice (F), because that word agrees with halcyon.
Choices (A) and (E) both convey done easily with skill, and can be eliminated. There is also no context to support a domineering journey,
and thus choice (D) is incorrect. That leaves choices (B) and (C), both of which mean twisted or not smooth and produce equivalent, appropriate sentences.
Hence options B and C fits.
