A.I. Explanation:

Correct answer: prompts

Explanation: The verb 'prompts' fits grammatically as it is in the present tense, which aligns with the context of the sentence discussing a regular occurrence. It indicates that the Spring Festival causes or initiates the migration, maintaining logical coherence with the subject of the sentence.

Meaning: 'Prompts' means to cause or bring about an action or event, in this case, the migration of people during the Spring Festival.

Wrong options:

• businesses: 'Businesses' is a noun that does not fit grammatically as it does not serve as a verb to indicate an action related to migration.
• controls: 'Controls' is a verb that implies regulation or management, which does not logically connect to the migration context here.
• reunions: 'Reunions' is a noun referring to gatherings, which does not fit as it does not indicate an action related to migration.
• kicking: 'Kicking' is a gerund that does not fit grammatically in this context as it does not convey the action of causing the migration.
• starting: 'Starting' is a gerund that implies the beginning of an action but does not fit the grammatical structure needed for this sentence.

Correct answer: kicking
