Question

yesterday _ (article) European called at my office

Answer 1

Answer:

Yesterday a European called at my office.

Answer 2

Yesterday, a European called at my office.

To solve this question,

• There are three common types of articles, a, an, and the.
• Here, which European called is not specified, so 'the' will not be used.
• Now, out of 'a' or 'an', which article will be used will depend on the word before which the article is to be placed.
• If the word starts with a consonant sound, then 'a' is used and if the word starts with a vowel sound 'an' is used.
• Here, 'European' is pronounced with /y/ which is a consonant. Hence, 'a' is used.
