When a sentence is written in the interrogative mood, the verb form should ask a question. To determine the verb form in the interrogative mood, you need to consider whether the sentence is posing a question or seeking information. Interrogative sentences usually begin with question words (who, what, when, where, why, how) or with a helping verb (such as do, can, will), followed by the subject and main verb. The verb form in the interrogative mood is essential for constructing a grammatically correct question.
