Question

Difficulty: MediumSubject-Verb Agreement (Concord)

Complete the sentence below by supplying the verb form that correctly satisfies the rules of grammatical concord.

Answer:The principal researcher, alongside several field assistants, 【is】 scheduled to present the findings at the international conference tomorrow.

Answer

is
When a singular subject is connected to another noun using expressions such as 'alongside', 'as well as', 'together with', or 'in addition to', the verb must agree with the singular principal subject ('principal researcher'). Therefore, the singular verb 'is' is required.

Step-by-Step Solution

1
Identify the primary grammatical subject of the sentence.
The main subject is 'The principal researcher', which is singular.
Phrases introduced by quasi-conjunctions or prepositional expressions like 'alongside', 'together with', or 'as well as' do not form a compound subject.
2
Determine the required number for the verb based on the primary subject.
A singular verb is required to agree with the singular noun 'researcher'.
Intervening plural nouns within the prepositional phrase ('field assistants') must be ignored when determining concord.
3
Select the correct present-tense auxiliary verb.
The singular verb 'is' correctly completes the passive sentence structure.
'is' agrees in number and tense with the singular subject.
