Question

Difficulty: MediumParallel Structure

The following sentence contains a blank. To maintain parallel structure, what form of the verb 'provide' should be written in the blank to complete the sentence?

Answer:The new digital archive not only preserves historical documents but also 【provides】 public access to rare manuscripts.

Answer

provides
The correct verb form is 'provides'. The correlative conjunction 'not only... but also' connects two actions of the subject 'archive'. Since the first action is written in the third-person singular present tense ('preserves'), the second action must match this form exactly ('provides') to maintain parallel structure.

Step-by-Step Solution

1
Identify the parallel elements in the sentence.
The sentence uses the correlative conjunction 'not only... but also' to connect two actions performed by the subject 'The new digital archive'.
Correlative conjunctions require the phrases they connect to be grammatically parallel.
2
Determine the grammatical form of the first parallel element.
The first element is 'preserves historical documents', which starts with the third-person singular present-tense verb 'preserves'.
This establishes the grammatical pattern that the second element must follow.
3
Match the verb form for the second parallel element.
The second element must also start with a third-person singular present-tense verb to maintain parallelism, which is 'provides'.
This completes the parallel structure 'not only preserves... but also provides'.

Key Concept

Parallel structure requires that words, phrases, or clauses in a series or joined by correlative conjunctions share the same grammatical form.
