Which of the following words is an Adverb?

Answer: 'Apace' is an adverb meaning 'quickly' or 'swiftly'.

• Fury — a noun meaning intense anger. Example: 'She reacted with fury.' It does not modify a verb, so it is not an adverb.

• Meek — an adjective describing a person or thing (e.g., 'a meek child'). Adjectives modify nouns, not verbs.

• Face — primarily a noun (part of the head) and can be used as a verb ('to face a problem'), but it is not an adverb.

• Apace — an adverb meaning 'quickly' or 'swiftly'. Example: 'The project progressed apace.' It modifies the verb 'progressed', which is the function of an adverb.

Therefore, 'Apace' is the correct adverb.
