Difficulty: MediumVerbs, Tenses, and Aspect

Complete the sentence below by supplying the grammatically correct form of the verb 'publish' in the blank.

Answer:By the time the international summit convenes next November, the panel of environmental experts 【will have published】 its final report on coastal erosion mitigation.

Answer

will have published
The phrase 'By the time...' establishes a specified future limit or reference point ('next November'). To denote an action that will be completed prior to that future point in time, standard English grammar requires the future perfect tense-aspect combination, formed by 'will have' followed by the past participle verb 'published'.

Step-by-Step Solution

1
Analyze the temporal markers and clause structure in the sentence.
The clause contains the future time reference 'By the time...' alongside a simple present verb 'convenes' indicating a future reference point.
Adverbial time clauses introduced by 'by the time' establish a deadline prior to which another action in the future will be completed.
2
Determine the appropriate verb tense and aspect.
The future perfect tense ('will have published') is required.
The future perfect aspect (will + have + past participle) expresses an action that will be completed prior to a specific moment or event in the future.
