Answer 1

By the time the troops arrive, the war will have ended.

• The sentence depicts an action that is supposed to occur in the future.
• The verb needs to be in the present tense.
• According to the subject-verb agreement, the subject 'troop' is in plural form with the addition of letter 's'. For such a subject, the form of the verb used will not have an 's' in the end.
• Hence, other options such as 'arrives' is not correct.
