Meaning: 'Cities' refers to large human settlements that are more complex than villages, typically with a higher population density.

Wrong options:

• consume: The verb 'consume' does not fit as it refers to using up resources rather than describing a type of dwelling area.
• involved: The adjective 'involved' does not describe a type of settlement and is grammatically incorrect in this context.
• residence: The noun 'residence' refers to a place where someone lives but does not convey the idea of a larger settlement like 'cities.'
• engaged: The word 'engaged' is a verb that does not fit as it does not describe a type of dwelling area.
• produce: The verb 'produce' does not relate to the concept of permanent dwelling areas and is not a noun.

Correct answer: produce

Explanation: The verb 'produce' fits grammatically as it describes the action that the people in the city do not perform. The context indicates that these individuals rely on others for food, making 'produce' the correct choice.

Meaning: 'Produce' means to create or grow something, particularly food in this context.

Wrong options:

• consume: The verb 'consume' implies using food rather than creating it, which contradicts the context of the sentence.
• involved: The adjective 'involved' does not convey an action related to food production and is not appropriate here.
• residence: The noun 'residence' does not relate to the action of creating food and is grammatically incorrect in this context.
• engaged: The word 'engaged' is a verb that does not fit as it does not describe the action of producing food.
• cities: The noun 'cities' does not fit as it does not describe an action related to food.

Correct answer: engaged

Explanation: The word 'engaged' is a past participle that fits grammatically and contextually, indicating that the people in the city are involved in activities that do not produce food. It aligns with the structure of the sentence.

Meaning: 'Engaged' means to be involved in or occupied with something, in this case, nonproductive activities.

Wrong options:

• consume: The verb 'consume' does not fit as it describes an action of using resources rather than being involved in activities.
• involved: The adjective 'involved' is similar but does not fit grammatically as it does not match the sentence structure.
• residence: The noun 'residence' does not relate to the action of being engaged in activities and is grammatically incorrect here.
• cities: The noun 'cities' does not fit as it does not describe an action or state of being engaged in activities.
• produce: The verb 'produce' does not fit as it describes an action contrary to the context of being engaged in nonproductive activities.
