Difficulty: EasySubject-Verb Agreement (Concord)

Every one of the newly admitted students _______ required to submit an official medical report before matriculation. Which of the following options correctly completes the sentence?

  1. isAnswer
  2. B
    are
  3. C
    were
  4. D
    have been

Answer

The singular verb 'is' correctly completes the sentence.
The head subject of the sentence is the expression 'Every one', which is singular and requires a singular verb. The intervening prepositional phrase 'of the newly admitted students' does not affect the grammatical number of the subject. Therefore, the singular verb 'is' maintains proper concord.

Step-by-Step Solution

1
Identify the true head subject of the clause
The head subject is the indefinite expression 'Every one', which is grammatically singular.
Prepositional phrases following the head subject (such as 'of the newly admitted students') do not change the number of the head subject.
2
Apply the rule of subject-verb agreement
A singular head subject requires a singular verb form.
Grammatical concord dictates that singular subjects take singular verbs.
3
Select the correct singular verb form
The singular verb 'is' satisfies grammatical concord.
Among the options, 'is' is the only singular verb matching the present context.
