Question

Difficulty: HardSubject-Verb Agreement

The following passage contains two blanks where verb forms are missing. What are the correct present-tense forms of the verbs that should fill these blanks to maintain proper subject-verb agreement?

Answer:Each of the linguistic features discovered in the isolated valley 【suggests】 that the language developed independently of neighboring dialects. Indeed, a team of researchers, accompanied by local guides and translators, 【studies】 the phonology of this unique tongue to document its history.

Answer

The correct verb forms are 'suggests' for the first blank and 'studies' for the second blank.
For the first blank, 'suggests' is correct because the subject is 'Each', which is a singular indefinite pronoun. The modifying prepositional phrase 'of the linguistic features' does not change the number of the subject. For the second blank, 'studies' is correct because the subject is the collective noun 'team', which is singular. The parenthetical phrase 'accompanied by local guides and translators' does not affect the number of the main subject.

Step-by-Step Solution

1
Identify the subject and its grammatical number for the first blank.
The subject is the indefinite pronoun 'Each', which is grammatically singular.
The prepositional phrase 'of the linguistic features' contains a plural noun but acts only as a modifier; it does not change the singular nature of the subject 'Each'.
2
Select the correct present-tense verb form for the first blank.
The singular verb form 'suggests' is chosen.
A singular subject requires a singular verb form to maintain proper subject-verb agreement.
3
Identify the subject and its grammatical number for the second blank.
The subject is the collective noun 'team', which is singular in this context.
The parenthetical phrase 'accompanied by local guides and translators' is set off by commas and does not alter the singular grammatical number of the subject 'team'.
4
Select the correct present-tense verb form for the second blank.
The singular verb form 'studies' is chosen.
A singular subject requires a singular verb form to maintain proper subject-verb agreement.

Key Concept
