Question

Difficulty: MediumSubject-Verb Agreement (Concord)

Which word correctly fills the blank to ensure proper subject-verb concord in the sentence below?

Answer:Dr. Adebayo is one of the prominent researchers who 【are】 actively advocating for renewable energy adoption in West Africa.

Answer

are
In sentences structured around the phrase 'one of the... who', the relative pronoun 'who' refers to the plural noun immediately preceding it ('researchers'). Consequently, the verb within the relative clause must be plural ('are').

Step-by-Step Solution

1
Identify the relative pronoun and its antecedent in the clause.
The relative pronoun is 'who', and its antecedent is the plural noun 'researchers'.
In the construction 'one of the [plural noun] who...', the relative pronoun 'who' refers back to the plural noun preceding it, not to 'one'.
2
Determine the required number (singular or plural) for the verb in the relative clause.
A plural verb form is required to match the plural antecedent 'researchers'.
A relative pronoun takes a verb that agrees in number with its antecedent.
3
Select the correct present continuous auxiliary verb form.
The plural auxiliary verb 'are' correctly completes 'are actively advocating'.
'Are' agrees in number with 'researchers' and maintains proper present continuous tense with 'advocating'.
