Question

Fill in the blank with an appropriate article.

Such a severe storm occurs only once in _______ decade.

• A. a
• B. an
• C. the
• D. No article

Answer 1

The correct option is A a

The statement implies that 'such a severe storm occurs only once in ONE decade'. 'One' can be replaced by the indefinite article 'a' as it precedes a word starting with a consonant sound.
