The document discusses rules for verb agreement in sentences with compound subjects connected with "either...or". It states that the verb should agree in number with the closer subject. It provides two examples where the verb agrees with the subject closer to it, making both sentences grammatically correct. It also provides examples of identifying the antecedent in sentences using "who" and "one".
31. This rule says that in the case of compound
subjects in “either…or” constructions, the verb should agree in
number with the subject closer to it. Thus, by virtue of the proximity
of their subjects to the verb, these sentences are both grammatically
correct: “Either Armand or his parents are responsible for this mess.”
“Either his parents or Armand (himself) is responsible for this mess.”
33. Examples (English)
•In the following construction, the boy is the
antecedent of who:
•The boy who pitched the game is worn out.
•In the following construction, a towel is the
antecedent of one:
•If you need one, there’s a towel in the top drawer.
