Meaning: 'Forecasts' means predictions or estimates about future events, particularly in contexts like economics or demographics.

Wrong options:

• goals: 'Goals' refers to objectives or aims, which does not fit the context of predicting future household structures.
• alms: 'Alms' refers to charitable donations, which is unrelated to the context of forecasting demographic changes.

Correct answer: occupancy

Explanation: The word 'occupancy' correctly refers to the state of being occupied, which is relevant to the context of households. It fits grammatically as a noun that describes the condition of households being single, aligning with the overall topic of household demographics.

Meaning: 'Occupancy' means the state of being occupied or inhabited, particularly in relation to living spaces.

Wrong options:

• household: 'Household' is a noun that refers to a group of people living together, but it does not fit the context of describing the state of being single.
• occupied: 'Occupied' is an adjective that describes something that is currently being used, but it does not fit grammatically as a noun in this context.
• family: 'Family' refers to a group of related individuals, which does not accurately describe the concept of single households.

Correct answer: deteriorating

Explanation: The term 'deteriorating' fits well as it describes a decline in the situation, which aligns with the context of social isolation. It is a present participle that indicates an ongoing process, matching the tense and meaning required in the sentence.

Meaning: 'Deteriorating' means becoming progressively worse, particularly in terms of social conditions or relationships.

Wrong options:

• damaging: 'Damaging' implies causing harm, but it does not convey the ongoing decline in the situation as effectively as 'deteriorating'.
• improving: 'Improving' suggests a positive change, which contradicts the context of the situation worsening.
• recovering: 'Recovering' indicates a return to a better state, which is opposite to the intended meaning of the situation getting worse.

Correct answer: declaring

Explanation: The word 'declaring' is suitable as it indicates making a formal statement about the crisis in friendship-making abilities. It fits grammatically as a present participle that describes the action being taken by some individuals in the context of the sentence.

Meaning: 'Declaring' means to announce something formally or officially, particularly in relation to a crisis or issue.

Wrong options:

• denouncing: 'Denouncing' implies publicly condemning something, which does not fit the context of discussing a crisis in friendship.
• releasing: 'Releasing' refers to making something available or letting go, which does not align with the context of making a statement about a crisis.
• requiring: 'Requiring' indicates a need for something, which does not fit the context of making a declaration about the situation.

Correct answer: spectacular

Explanation: The term 'spectacular' is appropriate as it conveys a sense of impressive or remarkable change in the number of friends. It fits grammatically as an adjective that describes the rise in friendship numbers, aligning with the positive sentiment of the sentence.

Meaning: 'Spectacular' means impressive or extraordinary, particularly in terms of significant changes or achievements.

Wrong options:

• amazing: While 'amazing' is a synonym, it does not convey the same level of grandeur as 'spectacular' in this context.
• applausive: 'Applausive' is not commonly used and does not fit the context of describing a rise in friendships effectively.
• special: 'Special' implies uniqueness but does not capture the impressive nature of the increase in friendships as well as 'spectacular' does.
