ExplanationThe blank should mean
“returning” or
“reappearing”, something that matches
“hearken back” and
“signs today.”A. evanescent means fleeting, temporary: not the main idea; it’s about reappearing, not disappearing quickly.
B. resurgent means increasing again, reviving: fits.
C. recrudescent means breaking out again (especially of something undesirable): fits.
D. transitory means temporary: not the point.
E. controversial means debatable: possible but not directly supported by the context about
“hearken back” and
“signs today.”F. inimical means harmful, hostile: not directly supported by the sentence’s main point of
“coming back.”The best pair is
B and
C, both mean reappearing/reviving.
Answer: B, C
