Which sentence correctly uses the article ‘a’ to mean ‘per’ or ‘each’?

Explanation

The indefinite article ‘a’ (or ‘an’) can be used in English to mean ‘per’ or ‘each’ when describing frequency or rate, as in ‘an apple a day,’ meaning one apple for each day. This distributive usage requires both articles to be present, an ‘an’ before ‘apple’ because it begins with a vowel sound, and a plain ‘a’ before ‘day’ meaning ‘per day.’ Explore more English MCQs on mcqstutor to keep practicing.
