Difficulty: HardVerbs, Tenses, and Aspect

Complete the sentence by supplying the correct form of the verb in brackets to express the appropriate temporal aspect.

Answer:By the time the special investigative commission presents its final report next month, the audit panel 【will have examined】 (examine) all the relevant financial records.

Answer

The correct form of the verb is 'will have examined'.
The sentence requires the future perfect tense ('will have examined') because the time prepositional phrase 'By the time...' accompanied by a present tense subordinate clause ('presents...') sets a future boundary by which the action in the main clause will already be accomplished.

Step-by-Step Solution

1
Identify the temporal marker and time frame in the sentence
The clause begins with 'By the time...' and includes a simple present verb ('presents') referencing a future time marker ('next month').
Temporal expressions introduced by 'by the time' paired with a simple present verb establish a future point of completion.
2
Determine the appropriate tense and aspect required for the main clause
The action of examining the financial records must be completed prior to the specified future deadline, requiring the future perfect tense.
The future perfect structure ('will have' + past participle) expresses an action that will be completed before a particular time or event in the future.
