Question

Difficulty: MediumParallel Structure

Complete the sentence by typing the correct form of the parenthesized verb 'publish' to maintain parallel structure.

Answer:The research paper concluded that the success of the project depended on analyzing the local ecology, interviewing the residents, and 【publishing】 (publish) the findings in a public forum.

Answer

publishing
The sentence contains a list of three actions: 'analyzing the local ecology', 'interviewing the residents', and the blank. The first two items are gerunds ('analyzing', 'interviewing'). To maintain parallel structure, the third item must also be a gerund. Therefore, the verb 'publish' must be written in its gerund form, 'publishing'.

Step-by-Step Solution

1
Identify the elements of the list in the sentence.
The list consists of three actions that the success of the project depended on: 'analyzing the local ecology', 'interviewing the residents', and the final action starting with the verb 'publish'.
Parallel structure requires that all items in a list or series have the same grammatical form.
2
Determine the grammatical form of the first two items in the list.
The words 'analyzing' and 'interviewing' are both gerunds (verb forms ending in -ing that function as nouns).
Establishing the pattern of the existing list items determines the form the final item must take.
3
Convert the verb 'publish' to match the gerund form of the other list items.
Changing 'publish' to the gerund form yields 'publishing'.
This makes the final element parallel to 'analyzing' and 'interviewing', completing the parallel structure of the sentence.

Key Concept

Parallel structure requires that words, phrases, or clauses in a series or list share the same grammatical form to ensure clarity and balance.
