Answer 2

The three kinds of articles are 'a', 'an' and 'the'. They are used before a noun.

Explanation:

• "His brother is the union leader."
• "A" and "an" are indefinite articles that are used in singular forms of nouns.
• "The" is a definite article that is usedwhen there is only one  before both singular and plural forms of nouns.
• "The" is used when we talk about one single thing which exists. for example, 'the sun', 'the moon' etc.,
• In the sentence given, we understand that generally there could be only one union leader.
• Therefore "the" is the right answer.
