Difficulty: EasySubject-Verb Agreement (Concord)

Which verb form correctly completes the sentence below?

'The quality of these newly imported fabrics _____ consistently high.'

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

Answer

The correct verb form is 'is' because the grammatical subject of the sentence is the singular noun 'quality'.
The sentence subject is the singular noun 'quality'. Modifying prepositional phrases like 'of these newly imported fabrics' do not affect the subject's number, so the singular present-tense verb 'is' is required.

Step-by-Step Solution

1
Identify the simple subject of the sentence
The head noun of the subject phrase is 'quality', which is singular.
The phrase 'of these newly imported fabrics' is a prepositional modifier and does not change the singular nature of the head noun.
2
Apply the rule of subject-verb concord
A singular subject takes a singular verb ('is').
Subject-verb agreement requires the verb to agree with the head noun rather than any intervening plural nouns.
