Which sentence uses correct subject-verb agreement?
A. Many of George Orwell's works tell of changing times in his native India.
B. Conflict within society and within families are central to Charles Dickens' fiction.
C. Both Nadine Gordimer and Doris Lessing writes stories about Africa.
D. Are either Lessing or Gordimer a Nobel Prize winner?
My choice would be A. It’s not B since “the conflict are” is incorrect. Not C since “they writes” is incorrect. And I believe D is incorrect since “a Nobel Prize winner” doesn’t agree with “are” — you could rewrite it as “The Nobel prize winner IS either Lessing or Gordimer”.
