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.

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:

• 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.
