A.I. Explanation:

Correct answer: urgent

Explanation: The word 'urgent' is an adjective that describes the situation created by the pandemic, indicating that it requires immediate attention. This fits grammatically as it modifies the noun 'situation' and aligns with the context of a crisis requiring prompt action.

Meaning: 'Urgent' means requiring immediate action or attention.

Wrong options:

• additional: The word 'additional' is an adjective that implies something extra or supplementary, which does not convey the critical nature of the situation as effectively as 'urgent.'
• system: The word 'system' is a noun that does not fit grammatically as it does not describe the situation; it is unrelated to the urgency of the context.
• cost: The word 'cost' is a noun that refers to the amount required to obtain something, which does not appropriately describe the nature of the situation.

Correct answer: contribution

Explanation: The term 'contribution' is a noun that refers to the act of giving or providing something, which fits contextually as it describes the efforts made to support the health system during the pandemic. It aligns with the idea of collective efforts to address the crisis.

Meaning: 'Contribution' refers to something that is given or provided to help achieve a goal.

Wrong options:

• additional: The word 'additional' is an adjective that does not fit as it does not convey the act of providing help; it merely suggests something extra.
• system: The word 'system' is a noun that does not fit in this context as it does not describe an action or effort related to the health system.
• cost: The word 'cost' is a noun that refers to an expense, which does not relate to the act of providing support or help.

Correct answer: system

Explanation: The word 'system' is a noun that refers to the organized structure of health services, making it the appropriate choice to describe the health infrastructure that needed support during the pandemic. It fits grammatically as it is the object of the preposition 'to.'

Meaning: 'System' refers to a set of connected things or parts forming a complex whole, in this case, the health services.

Wrong options:

• urgent: The word 'urgent' is an adjective that does not fit here as it does not describe a noun related to health services.
• contribution: The word 'contribution' is a noun that does not fit grammatically as it does not refer to a structure or organization.
• sector: The word 'sector' is a noun that refers to a distinct part of a larger system, but it does not specifically denote the health services as 'system' does.

Correct answer: sector

Explanation: The term 'sector' is a noun that refers to a distinct part of an economy or industry, which fits contextually as it describes the pharmaceutical industry that needed reform during the pandemic. It aligns with the overall theme of addressing different areas affected by the crisis.

Meaning: 'Sector' refers to a specific area or division within a larger context, such as the pharmaceutical industry.

Wrong options:

• urgent: The word 'urgent' is an adjective that does not fit as it does not describe a part of the industry.
• contribution: The word 'contribution' is a noun that does not fit grammatically as it does not refer to a sector or industry.
• system: The word 'system' is a noun that refers to an organized structure, but it does not specifically denote the pharmaceutical industry.

Correct answer: throughout

Explanation: The word 'throughout' is a preposition that indicates something happening in every part of a place or during the entire duration of a time, which fits contextually as it describes the distribution of relief across the entire country. It maintains grammatical coherence with the verb 'distribute.'

Meaning: 'Throughout' means in every part of a place or during the whole of a period.

Wrong options:

• additional: The word 'additional' is an adjective that does not fit as it does not convey the sense of distribution across a space or time.
• system: The word 'system' is a noun that does not fit grammatically as it does not relate to the action of distributing relief.
• cost: The word 'cost' is a noun that refers to an expense, which does not relate to the distribution of relief.
