Zorluk: OrtaVerbs, Tenses, and Aspect

Which verb form correctly completes the sentence to express an action that will be completed before a specified point in the future?

Cevap:By the time the international trade summit concludes next Friday, the delegation 【will have signed】 the bilateral agreement on agricultural exports.

Cevap

The correct verb form to fill the blank is 'will have signed'.
The future perfect aspect 'will have signed' is required because the introductory clause 'By the time...' establishes a future point of reference before which the action of signing must be completed.

Adım Adım Çözüm

1
Identify the temporal marker and clause relationship.
The time phrase 'By the time...' establishes a future deadline relative to another future event ('concludes').
The preposition 'by' combined with a time expression denotes an action completed no later than that reference time.
2
Select the appropriate tense and aspect.
The future perfect tense ('will have' + past participle 'signed') correctly expresses the completion of an action prior to a specified future moment.
Simple future ('will sign') or present perfect ('has signed') fail to project completion prior to a future point in time.
